Asparagales Asparagales (asparagoid lilies) is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species. The order is clearly circumscribed on the basis of molecular phylogenetics, but it is difficult to define morphologically since its members are structurally diverse. Most species of Asparagales are herbaceous perennials, although some are climbers and some are tree-like. The order also contains many geophytes (bulbs, corms, and various kinds of tuber). According to telomere sequence, at least two evolutionary switch-points happened within the order. The basal sequence is formed by TTTAGGG like in the majority of higher plants. Basal motif was changed to vertebrate-like TTAGGG and finally, the most divergent motif CTCGGTTATGGG appears in Allium. One of the defining characteristics (synapomorphies) of the order is the presence of phytomelanin, a black pigment present in the seed coat, creating a dark crust. Phytomelanin is found in most families of the Asparagales (although not in Orchidaceae, thought to be the sister-group of the rest of the order). The leaves of almost all species form a tight rosette, either at the base of the plant or at the end of the stem, but occasionally along the stem. The flowers are not particularly distinctive, being 'lily type', with six tepals and up to six stamina. The order is thought to have first diverged from other related monocots some 120–130 million years ago (early in the Cretaceous period), although given the difficulty in classifying the families involved, estimates are likely to be uncertain. From an economic point of view, the order Asparagales is second in importance within the monocots only to the order Poales (which includes grasses and cereals). Species are used as food and flavourings (e.g. onion, garlic, leek, asparagus, vanilla, saffron), in medicinal or cosmetic applications (Aloe), as cut flowers (e.g. freesia, gladiolus, iris, orchids), and as garden ornamentals (e.g. day lilies, lily of the valley, Agapanthus).

Asparagales Asparagales (asparagoid lilies) is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009.

DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species. The order is clearly circumscribed on the basis of molecular phylogenetics, but it is difficult to define morphologically since its members are structurally diverse. Most species of Asparagales are herbaceous perennials, although some are climbers and some are tree-like. The order also contains many geophytes (bulbs, corms, and various kinds of tuber). According to telomere sequence, at least two evolutionary switch-points happened within the order. The basal sequence is formed by TTTAGGG like in the majority of higher plants. Basal motif was changed to vertebrate-like TTAGGG and finally, the most divergent motif CTCGGTTATGGG appears in Allium. One of the defining characteristics (synapomorphies) of the order is the presence of phytomelanin, a black pigment present in the seed coat, creating a dark crust. Phytomelanin is found in most families of the Asparagales (although not in Orchidaceae, thought to be the sister-group of the rest of the order). The leaves of almost all species form a tight rosette, either at the base of the plant or at the end of the stem, but occasionally along the stem. The flowers are not particularly distinctive, being 'lily type', with six tepals and up to six stamina. The order is thought to have first diverged from other related monocots some 120–130 million years ago (early in the Cretaceous period), although given the difficulty in classifying the families involved, estimates are likely to be uncertain. From an economic point of view, the order Asparagales is second in importance within the monocots only to the order Poales (which includes grasses and cereals). Species are used as food and flavourings (e.g. onion, garlic, leek, asparagus, vanilla, saffron), in medicinal or cosmetic applications (Aloe), as cut flowers (e.g. freesia, gladiolus, iris, orchids), and as garden ornamentals (e.g. day lilies, lily of the valley, Agapanthus).

Description Although most species in the order are herbaceous, some no more than 15 cm high, there are a number of climbers (e.g., some species of Asparagus), as well as several genera forming trees (e.g. Agave, Cordyline, Yucca, Dracaena, Aloe ), which can exceed 10 m in height. Succulent genera occur in several families (e.g. Aloe). Almost all species have a tight cluster of leaves (a rosette), either at the base of the plant or at the end of a more-or-less woody stem as with Yucca. In some cases, the leaves are produced along the stem. The flowers are in the main not particularly distinctive, being of a general 'lily type', with six tepals, either free or fused from the base and up to six stamina. They are frequently clustered at the end of the plant stem. The Asparagales are generally distinguished from the Liliales by the lack of markings on the tepals, the presence of septal nectaries in the ovaries, rather than the bases of the tepals or stamen filaments, and the presence of secondary growth. They are generally geophytes, but with linear leaves, and a lack of fine reticular venation. The seeds characteristically have the external epidermis either obliterated (in most species bearing fleshy fruit), or if present, have a layer of black carbonaceous phytomelanin in species with dry fruits (nuts). The inner part of the seed coat is generally collapsed, in contrast to Liliales whose seeds have a well developed outer epidermis, lack phytomelanin, and usually display a cellular inner layer. The orders which have been separated from the old Liliales are difficult to characterize. No single morphological character appears to be diagnostic of the order Asparagales. The flowers of Asparagales are of a general type among the lilioid monocots. Compared to Liliales, they usually have plain tepals without markings in the form of dots. If nectaries are present, they are in the septa of the ovaries rather than at the base of the tepals or stamens. Those species which have relatively large dry seeds have a dark, crust-like (crustose) outer layer containing the pigment phytomelan. However, some species with hairy seeds (e.g. Eriospermum, family Asparagaceae s.l. ), berries (e.g. Maianthemum, family Asparagaceae s.l. ), or highly reduced seeds (e.g. orchids) lack this dark pigment in their seed coats. Phytomelan is not unique to Asparagales (i.e. it is not a synapomorphy) but it is common within the order and rare outside it. The inner portion of the seed coat is usually completely collapsed. In contrast, the morphologically similar seeds of Liliales have no phytomelan, and usually retain a cellular structure in the inner portion of the seed coat. Most monocots are unable to thicken their stems once they have formed, since they lack the cylindrical meristem present in other angiosperm groups. Asparagales have a method of secondary thickening which is otherwise only found in Dioscorea (in the monocot order Disoscoreales).

Asparagales have a method of secondary thickening which is otherwise only found in Dioscorea (in the monocot order Disoscoreales).

In a process called 'anomalous secondary growth', they are able to create new vascular bundles around which thickening growth occurs. Agave, Yucca, Aloe, Dracaena, Nolina and Cordyline can become massive trees, albeit not of the height of the tallest dicots, and with less branching. Other genera in the order, such as Lomandra and Aphyllanthes, have the same type of secondary growth but confined to their underground stems. Microsporogenesis (part of pollen formation) distinguishes some members of Asparagales from Liliales. Microsporogenesis involves a cell dividing twice (meiotically) to form four daughter cells. There are two kinds of microsporogenesis: successive and simultaneous (although intermediates exist). In successive microsporogenesis, walls are laid down separating the daughter cells after each division. In simultaneous microsporogenesis, there is no wall formation until all four cell nuclei are present. Liliales all have successive microsporogenesis, which is thought to be the primitive condition in monocots. It seems that when the Asparagales first diverged they developed simultaneous microsporogenesis, which the 'lower' Asparagale families retain. However, the 'core' Asparagales (see Phylogenetics ) have reverted to successive microsporogenesis. The Asparagales appear to be unified by a mutation affecting their telomeres (a region of repetitive DNA at the end of a chromosome). The typical 'Arabidopsis-type' sequence of bases has been fully or partially replaced by other sequences, with the 'human-type' predominating. Other apomorphic characters of the order according to Stevens are: the presence of chelidonic acid, anthers longer than wide, tapetal cells bi- to tetra-nuclear, tegmen not persistent, endosperm helobial, and loss of mitochondrial gene sdh3. Taxonomy As circumscribed within the Angiosperm Phylogeny Group system Asparagales is the largest order within the monocotyledons, with 14 families, 1,122 genera and about 25,000–42,000 species, thus accounting for about 50% of all monocots and 10–15% of the flowering plants (angiosperms). The attribution of botanical authority for the name Asparagales belongs to Johann Heinrich Friedrich Link (1767–1851) who coined the word 'Asparaginae' in 1829 for a higher order taxon that included Asparagus although Adanson and Jussieau had also done so earlier (see History). Earlier circumscriptions of Asparagales attributed the name to Bromhead (1838), who had been the first to use the term 'Asparagales'. History Pre-Darwinian The type genus, Asparagus, from which the name of the order is derived, was described by Carl Linnaeus in 1753, with ten species. He placed Asparagus within the Hexandria Monogynia (six stamens, one carpel) in his sexual classification in the Species Plantarum. The majority of taxa now considered to constitute Asparagales have historically been placed within the very large and diverse family, Liliaceae. The family Liliaceae was first described by Michel Adanson in 1763, and in his taxonomic scheme he created eight sections within it, including the Asparagi with Asparagus and three other genera. The system of organising genera into families is generally credited to Antoine Laurent de Jussieu who formally described both the Liliaceae and the type family of Asparagales, the Asparagaceae, as Lilia and Asparagi, respectively, in 1789.

The system of organising genera into families is generally credited to Antoine Laurent de Jussieu who formally described both the Liliaceae and the type family of Asparagales, the Asparagaceae, as Lilia and Asparagi, respectively, in 1789.

Jussieu established the hierarchical system of taxonomy (phylogeny), placing Asparagus and related genera within a division of Monocotyledons, a class (III) of Stamina Perigynia and 'order' Asparagi, divided into three subfamilies. The use of the term Ordo (order) at that time was closer to what we now understand as Family, rather than Order. In creating his scheme he used a modified form of Linnaeus' sexual classification but using the respective topography of stamens to carpels rather than just their numbers. While De Jussieu's Stamina Perigynia also included a number of 'orders' that would eventually form families within the Asparagales such as the Asphodeli (Asphodelaceae), Narcissi (Amaryllidaceae) and Irides (Iridaceae), the remainder are now allocated to other orders. Jussieu's Asparagi soon came to be referred to as Asparagacées in the French literature (Latin: Asparagaceae). Meanwhile, the 'Narcissi' had been renamed as the 'Amaryllidées' (Amaryllideae) in 1805, by Jean Henri Jaume Saint-Hilaire, using Amaryllis as the type species rather than Narcissus, and thus has the authority attribution for Amaryllidaceae. In 1810, Brown proposed that a subgroup of Liliaceae be distinguished on the basis of the position of the ovaries and be referred to as Amaryllideae and in 1813 de Candolle described Liliacées Juss. and Amaryllidées Brown as two quite separate families. The literature on the organisation of genera into families and higher ranks became available in the English language with Samuel Frederick Gray's A natural arrangement of British plants (1821). Gray used a combination of Linnaeus' sexual classification and Jussieu's natural classification to group together a number of families having in common six equal stamens, a single style and a perianth that was simple and petaloid, but did not use formal names for these higher ranks. Within the grouping he separated families by the characteristics of their fruit and seed. He treated groups of genera with these characteristics as separate families, such as Amaryllideae, Liliaceae, Asphodeleae and Asparageae. The circumscription of Asparagales has been a source of difficulty for many botanists from the time of John Lindley (1846), the other important British taxonomist of the early nineteenth century. In his first taxonomic work, An Introduction to the Natural System of Botany (1830) he partly followed Jussieu by describing a subclass he called Endogenae, or Monocotyledonous Plants (preserving de Candolle's Endogenæ phanerogamæ) divided into two tribes, the Petaloidea and Glumaceae. He divided the former, often referred to as petaloid monocots, into 32 orders, including the Liliaceae (defined narrowly), but also most of the families considered to make up the Asparagales today, including the Amaryllideae. By 1846, in his final scheme Lindley had greatly expanded and refined the treatment of the monocots, introducing both an intermediate ranking (Alliances) and tribes within orders (i.e. families). Lindley placed the Liliaceae within the Liliales, but saw it as a paraphyletic ("catch-all") family, being all Liliales not included in the other orders, but hoped that the future would reveal some characteristic that would group them better.

Gray used a combination of Linnaeus' sexual classification and Jussieu's natural classification to group together a number of families having in common six equal stamens, a single style and a perianth that was simple and petaloid, but did not use formal names for these higher ranks. Within the grouping he separated families by the characteristics of their fruit and seed. He treated groups of genera with these characteristics as separate families, such as Amaryllideae, Liliaceae, Asphodeleae and Asparageae. The circumscription of Asparagales has been a source of difficulty for many botanists from the time of John Lindley (1846), the other important British taxonomist of the early nineteenth century. In his first taxonomic work, An Introduction to the Natural System of Botany (1830) he partly followed Jussieu by describing a subclass he called Endogenae, or Monocotyledonous Plants (preserving de Candolle's Endogenæ phanerogamæ) divided into two tribes, the Petaloidea and Glumaceae. He divided the former, often referred to as petaloid monocots, into 32 orders, including the Liliaceae (defined narrowly), but also most of the families considered to make up the Asparagales today, including the Amaryllideae. By 1846, in his final scheme Lindley had greatly expanded and refined the treatment of the monocots, introducing both an intermediate ranking (Alliances) and tribes within orders (i.e. families). Lindley placed the Liliaceae within the Liliales, but saw it as a paraphyletic ("catch-all") family, being all Liliales not included in the other orders, but hoped that the future would reveal some characteristic that would group them better.

The order Liliales was very large and had become a used to include almost all monocotyledons with colourful tepals and without starch in their endosperm (the lilioid monocots). The Liliales was difficult to divide into families because morphological characters were not present in patterns that clearly demarcated groups. This kept the Liliaceae separate from the Amaryllidaceae (Narcissales). Of these Liliaceae was divided into eleven tribes (with 133 genera) and Amaryllidaceae into four tribes (with 68 genera), yet both contained many genera that would eventually segregate to each other's contemporary orders (Liliales and Asparagales respectively). The Liliaceae would be reduced to a small 'core' represented by the tribe Tulipae, while large groups such Scilleae and Asparagae would become part of Asparagales either as part of the Amaryllidaceae or as separate families. While of the Amaryllidaceae, the Agaveae would be part of Asparagaceae but the Alstroemeriae would become a family within the Liliales. The number of known genera (and species) continued to grow and by the time of the next major British classification, that of the Bentham & Hooker system in 1883 (published in Latin) several of Lindley's other families had been absorbed into the Liliaceae. They used the term 'series' to indicate suprafamilial rank, with seven series of monocotyledons (including Glumaceae), but did not use Lindley's terms for these. However they did place the Liliaceous and Amaryllidaceous genera into separate series. The Liliaceae were placed in series Coronariae, while the Amaryllideae were placed in series Epigynae. The Liliaceae now consisted of twenty tribes (including Tulipeae, Scilleae and Asparageae), and the Amaryllideae of five (including Agaveae and Alstroemerieae). An important addition to the treatment of the Liliaceae was the recognition of the Allieae as a distinct tribe that would eventually find its way to the Asparagales as the subfamily Allioideae of the Amaryllidaceae. Post-Darwinian The appearance of Charles Darwin's Origin of Species in 1859 changed the way that taxonomists considered plant classification, incorporating evolutionary information into their schemata. The Darwinian approach led to the concept of phylogeny (tree-like structure) in assembling classification systems, starting with Eichler. Eichler, having established a hierarchical system in which the flowering plants (angiosperms) were divided into monocotyledons and dicotyledons, further divided into former into seven orders. Within the Liliiflorae were seven families, including Liliaceae and Amaryllidaceae. Liliaceae included Allium and Ornithogalum (modern Allioideae) and Asparagus. Engler, in his system developed Eichler's ideas into a much more elaborate scheme which he treated in a number of works including Die Natürlichen Pflanzenfamilien (Engler and Prantl 1888) and Syllabus der Pflanzenfamilien (1892–1924). In his treatment of Liliiflorae the Liliineae were a suborder which included both families Liliaceae and Amaryllidaceae. The Liliaceae had eight subfamilies and the Amaryllidaceae four. In this rearrangement of Liliaceae, with fewer subdivisions, the core Liliales were represented as subfamily Lilioideae (with Tulipae and Scilleae as tribes), the Asparagae were represented as Asparagoideae and the Allioideae was preserved, representing the alliaceous genera. Allieae, Agapantheae and Gilliesieae were the three tribes within this subfamily.

In the Amaryllidacea, there was little change from the Bentham & Hooker. A similar approach was adopted by Wettstein. Twentieth century In the twentieth century the Wettstein system (1901–1935) placed many of the taxa in an order called 'Liliiflorae'. Next Johannes Paulus Lotsy (1911) proposed dividing the Liliiflorae into a number of smaller families including Asparagaceae. Then Herbert Huber (1969, 1977), following Lotsy's example, proposed that the Liliiflorae be split into four groups including the 'Asparagoid' Liliiflorae. The widely used Cronquist system (1968–1988) used the very broadly defined order Liliales. These various proposals to separate small groups of genera into more homogeneous families made little impact till that of Dahlgren (1985) incorporating new information including synapomorphy. Dahlgren developed Huber's ideas further and popularised them, with a major deconstruction of existing families into smaller units. They created a new order, calling it Asparagales. This was one of five orders within the superorder Liliiflorae. Where Cronquist saw one family, Dahlgren saw forty distributed over three orders (predominantly Liliales and Asparagales). Over the 1980s, in the context of a more general review of the classification of angiosperms, the Liliaceae were subjected to more intense scrutiny. By the end of that decade, the Royal Botanic Gardens at Kew, the British Museum of Natural History and the Edinburgh Botanical Gardens formed a committee to examine the possibility of separating the family at least for the organization of their herbaria. That committee finally recommended that 24 new families be created in the place of the original broad Liliaceae, largely by elevating subfamilies to the rank of separate families. The order Asparagales as currently circumscribed has only recently been recognized in classification systems, through the advent of phylogenetics. The 1990s saw considerable progress in plant phylogeny and phylogenetic theory, enabling a phylogenetic tree to be constructed for all of the flowering plants. The establishment of major new clades necessitated a departure from the older but widely used classifications such as Cronquist and Thorne based largely on morphology rather than genetic data. This complicated discussion about plant evolution and necessitated a major restructuring. rbcL gene sequencing and cladistic analysis of monocots had redefined the Liliales in 1995. from four morphological orders sensu Dahlgren. The largest clade representing the Liliaceae, all previously included in Liliales, but including both the Calochortaceae and Liliaceae sensu Tamura. This redefined family, that became referred to as core Liliales, but corresponded to the emerging circumscription of the Angiosperm Phylogeny Group (1998). Phylogeny and APG system The 2009 revision of the Angiosperm Phylogeny Group system, APG III, places the order in the clade monocots. From the Dahlgren system of 1985 onwards, studies based mainly on morphology had identified the Asparagales as a distinct group, but had also included groups now located in Liliales, Pandanales and Zingiberales.

Research in the 21st century has supported the monophyly of Asparagales, based on morphology, 18S rDNA, and other DNA sequences, although some phylogenetic reconstructions based on molecular data have suggested that Asparagales may be paraphyletic, with Orchidaceae separated from the rest. Within the monocots, Asparagales is the sister group of the commelinid clade. This cladogram shows the placement of Asparagales within the orders of Lilianae sensu Chase & Reveal (monocots) based on molecular phylogenetic evidence. The lilioid monocot orders are bracketed, namely Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales. These constitute a paraphyletic assemblage, that is groups with a common ancestor that do not include all direct descendants (in this case commelinids as the sister group to Asparagales); to form a clade, all the groups joined by thick lines would need to be included. While Acorales and Alismatales have been collectively referred to as "alismatid monocots" (basal or early branching monocots), the remaining clades (lilioid and commelinid monocots) have been referred to as the "core monocots". The relationship between the orders (with the exception of the two sister orders) is pectinate, that is diverging in succession from the line that leads to the commelinids. Numbers indicate crown group (most recent common ancestor of the sampled species of the clade of interest) divergence times in mya (million years ago). Subdivision A phylogenetic tree for the Asparagales, generally to family level, but including groups which were recently and widely treated as families but which are now reduced to subfamily rank, is shown below. The tree shown above can be divided into a basal paraphyletic group, the 'lower Asparagales (asparagoids)', from Orchidaceae to Asphodelaceae, and a well-supported monophyletic group of 'core Asparagales' (higher asparagoids), comprising the two largest families, Amaryllidaceae sensu lato and Asparagaceae sensu lato. Two differences between these two groups (although with exceptions) are: the mode of microsporogenesis and the position of the ovary. The 'lower Asparagales' typically have simultaneous microsporogenesis (i.e. cell walls develop only after both meiotic divisions), which appears to be an apomorphy within the monocots, whereas the 'core Asparagales' have reverted to successive microsporogenesis (i.e. cell walls develop after each division). The 'lower Asparagales' typically have an inferior ovary, whereas the 'core Asparagales' have reverted to a superior ovary. A 2002 morphological study by Rudall treated possessing an inferior ovary as a synapomorphy of the Asparagales, stating that reversions to a superior ovary in the 'core Asparagales' could be associated with the presence of nectaries below the ovaries. However, Stevens notes that superior ovaries are distributed among the 'lower Asparagales' in such a way that it is not clear where to place the evolution of different ovary morphologies. The position of the ovary seems a much more flexible character (here and in other angiosperms) than previously thought. Changes to family structure in APG III The APG III system when it was published in 2009, greatly expanded the families Xanthorrhoeaceae, Amaryllidaceae, and Asparagaceae.

Two differences between these two groups (although with exceptions) are: the mode of microsporogenesis and the position of the ovary.

Changes to family structure in APG III The APG III system when it was published in 2009, greatly expanded the families Xanthorrhoeaceae, Amaryllidaceae, and Asparagaceae.

Thirteen of the families of the earlier APG II system were thereby reduced to subfamilies within these three families. The expanded Xanthorrhoeaceae is now called "Asphodelaceae". The APG II families (left) and their equivalent APG III subfamilies (right) are as follows: Structure of Asparagales Orchid clade Orchidaceae is possibly the largest family of all angiosperms (only Asteraceae might - or might not - be more speciose) and hence by far the largest in the order. The Dahlgren system recognized three families of orchids, but DNA sequence analysis later showed that these families are polyphyletic and so should be combined. Several studies suggest (with high bootstrap support) that Orchidaceae is the sister of the rest of the Asparagales. Other studies have placed the orchids differently in the phylogenetic tree, generally among the Boryaceae-Hypoxidaceae clade. The position of Orchidaceae shown above seems the best current hypothesis, but cannot be taken as confirmed. Orchids have simultaneous microsporogenesis and inferior ovaries, two characters that are typical of the 'lower Asparagales'. However, their nectaries are rarely in the septa of the ovaries, and most orchids have dust-like seeds, atypical of the rest of the order. (Some members of Vanilloideae and Cypripedioideae have crustose seeds, probably associated with dispersal by birds and mammals that are attracted by fermenting fleshy fruit releasing fragrant compounds, e.g. vanilla.) In terms of the number of species, Orchidaceae diversification is remarkable. However, although the other Asparagales may be less rich in species, they are more variable morphologically, including tree-like forms. Boryaceae to Hypoxidaceae The four families excluding Boryaceae form a well-supported clade in studies based on DNA sequence analysis. All four contain relatively few species, and it has been suggested that they be combined into one family under the name Hypoxidaceae sensu lato. The relationship between Boryaceae (which includes only two genera, Borya and Alania), and other Asparagales has remained unclear for a long time. The Boryaceae are mycorrhizal, but not in the same way as orchids. Morphological studies have suggested a close relationship between Boryaceae and Blandfordiaceae. There is relatively low support for the position of Boryaceae in the tree shown above. Ixioliriaceae to Xeronemataceae The relationship shown between Ixioliriaceae and Tecophilaeaceae is still unclear. Some studies have supported a clade of these two families, others have not. The position of Doryanthaceae has also varied, with support for the position shown above, but also support for other positions. The clade from Iridaceae upwards appears to have stronger support. All have some genetic characteristics in common, having lost Arabidopsis-type telomeres. Iridaceae is distinctive among the Asparagales in the unique structure of the inflorescence (a rhipidium), the combination of an inferior ovary and three stamens, and the common occurrence of unifacial leaves whereas bifacial leaves are the norm in other Asparagales. Members of the clade from Iridaceae upwards have infra-locular septal nectaries, which Rudall interpreted as a driver towards secondarily superior ovaries. Asphodelaceae + 'core Asparagales' The next node in the tree (Xanthorrhoeaceae sensu lato + the 'core Asparagales') has strong support.

Thirteen of the families of the earlier APG II system were thereby reduced to subfamilies within these three families. The expanded Xanthorrhoeaceae is now called "Asphodelaceae". The APG II families (left) and their equivalent APG III subfamilies (right) are as follows: Structure of Asparagales Orchid clade Orchidaceae is possibly the largest family of all angiosperms (only Asteraceae might - or might not - be more speciose) and hence by far the largest in the order. The Dahlgren system recognized three families of orchids, but DNA sequence analysis later showed that these families are polyphyletic and so should be combined. Several studies suggest (with high bootstrap support) that Orchidaceae is the sister of the rest of the Asparagales. Other studies have placed the orchids differently in the phylogenetic tree, generally among the Boryaceae-Hypoxidaceae clade. The position of Orchidaceae shown above seems the best current hypothesis, but cannot be taken as confirmed. Orchids have simultaneous microsporogenesis and inferior ovaries, two characters that are typical of the 'lower Asparagales'. However, their nectaries are rarely in the septa of the ovaries, and most orchids have dust-like seeds, atypical of the rest of the order. (Some members of Vanilloideae and Cypripedioideae have crustose seeds, probably associated with dispersal by birds and mammals that are attracted by fermenting fleshy fruit releasing fragrant compounds, e.g. vanilla.) In terms of the number of species, Orchidaceae diversification is remarkable. However, although the other Asparagales may be less rich in species, they are more variable morphologically, including tree-like forms. Boryaceae to Hypoxidaceae The four families excluding Boryaceae form a well-supported clade in studies based on DNA sequence analysis. All four contain relatively few species, and it has been suggested that they be combined into one family under the name Hypoxidaceae sensu lato. The relationship between Boryaceae (which includes only two genera, Borya and Alania), and other Asparagales has remained unclear for a long time. The Boryaceae are mycorrhizal, but not in the same way as orchids. Morphological studies have suggested a close relationship between Boryaceae and Blandfordiaceae. There is relatively low support for the position of Boryaceae in the tree shown above. Ixioliriaceae to Xeronemataceae The relationship shown between Ixioliriaceae and Tecophilaeaceae is still unclear. Some studies have supported a clade of these two families, others have not. The position of Doryanthaceae has also varied, with support for the position shown above, but also support for other positions. The clade from Iridaceae upwards appears to have stronger support. All have some genetic characteristics in common, having lost Arabidopsis-type telomeres. Iridaceae is distinctive among the Asparagales in the unique structure of the inflorescence (a rhipidium), the combination of an inferior ovary and three stamens, and the common occurrence of unifacial leaves whereas bifacial leaves are the norm in other Asparagales. Members of the clade from Iridaceae upwards have infra-locular septal nectaries, which Rudall interpreted as a driver towards secondarily superior ovaries. Asphodelaceae + 'core Asparagales' The next node in the tree (Xanthorrhoeaceae sensu lato + the 'core Asparagales') has strong support.

Asphodelaceae + 'core Asparagales' The next node in the tree (Xanthorrhoeaceae sensu lato + the 'core Asparagales') has strong support.

'Anomalous' secondary thickening occurs among this clade, e.g. in Xanthorrhoea (family Asphodelaceae) and Dracaena (family Asparagaceae sensu lato), with species reaching tree-like proportions. The 'core Asparagales', comprising Amaryllidaceae sensu lato and Asparagaceae sensu lato, are a strongly supported clade, as are clades for each of the families. Relationships within these broadly defined families appear less clear, particularly within the Asparagaceae sensu lato. Stevens notes that most of its subfamilies are difficult to recognize, and that significantly different divisions have been used in the past, so that the use of a broadly defined family to refer to the entire clade is justified. Thus the relationships among subfamilies shown above, based on APWeb , is somewhat uncertain. Evolution Several studies have attempted to date the evolution of the Asparagales, based on phylogenetic evidence. Earlier studies generally give younger dates than more recent studies, which have been preferred in the table below. A 2009 study suggests that the Asparagales have the highest diversification rate in the monocots, about the same as the order Poales, although in both orders the rate is little over half that of the eudicot order Lamiales, the clade with the highest rate. Comparison of family structures The taxonomic diversity of the monocotyledons is described in detail by Kubitzki. Up-to-date information on the Asparagales can be found on the Angiosperm Phylogeny Website. The APG III system's family circumscriptions are being used as the basis of the Kew-hosted World Checklist of Selected Plant Families. With this circumscription, the order consists of 14 families (Dahlgren had 31) with approximately 1120 genera and 26000 species. Order Asparagales Link Family Amaryllidaceae J.St.-Hil.

Alismatales The Alismatales (alismatids) are an order of flowering plants including about 4500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Description The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either floating or emergent. Vegetation may be totally submersed, have floating leaves, or protrude from the water. Collectively, they are commonly known as "water plantain". Taxonomy The Alismatales contain about 165 genera in 13 families, with a cosmopolitan distribution. Phylogenetically, they are basal monocots, diverging early in evolution relative to the lilioid and commelinid monocot lineages. Together with the Acorales, the Alismatales are referred to informally as the alismatid monocots. Early systems The Cronquist system (1981) places the Alismatales in subclass Alismatidae, class Liliopsida [= monocotyledons] and includes only three families as shown: Alismataceae Butomaceae Limnocharitaceae Cronquist's subclass Alismatidae conformed fairly closely to the order Alismatales as defined by APG, minus the Araceae. The Dahlgren system places the Alismatales in the superorder Alismatanae in the subclass Liliidae [= monocotyledons] in the class Magnoliopsida [= angiosperms] with the following families included: Alismataceae Aponogetonaceae Butomaceae Hydrocharitaceae Limnocharitaceae In Tahktajan's classification (1997), the order Alismatales contains only the Alismataceae and Limnocharitaceae, making it equivalent to the Alismataceae as revised in APG-III. Other families included in the Alismatates as currently defined are here distributed among 10 additional orders, all of which are assigned, with the following exception, to the Subclass Alismatidae. Araceae in Tahktajan 1997 is assigned to the Arales and placed in the Subclass Aridae; Tofieldiaceae to the Melanthiales and placed in the Liliidae. Angiosperm Phylogeny Group The Angiosperm Phylogeny Group system (APG) of 1998 and APG II (2003) assigned the Alismatales to the monocots, which may be thought of as an unranked clade containing the families listed below. The biggest departure from earlier systems (see below) is the inclusion of family Araceae. By its inclusion, the order has grown enormously in number of species. The family Araceae alone accounts for about a hundred genera, totaling over two thousand species. The rest of the families together contain only about five hundred species, many of which are in very small families.

The APG III system (2009) differs only in that the Limnocharitaceae are combined with the Alismataceae; it was also suggested that the genus Maundia (of the Juncaginaceae) could be separated into a monogeneric family, the Maundiaceae, but the authors noted that more study was necessary before the Maundiaceae could be recognized. order Alismatales sensu APG III family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family Zosteraceae In APG IV (2016), it was decided that evidence was sufficient to elevate Maundia to family level as the monogeneric Maundiaceae. The authors considered including a number of the smaller orders within the Juncaginaceae, but an online survey of botanists and other users found little support for this "lumping" approach. Consequently, the family structure for APG IV is: family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Maundiaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family Zosteraceae Phylogeny Cladogram showing the orders of monocots (Lilianae sensu Chase & Reveal) based on molecular phylogenetic evidence: References Further reading B.

Apiales The Apiales are an order of flowering plants. The families are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation and in particular, the Torriceliaceae may be divided. Under this definition, well-known members include carrots, celery, parsley, and Hedera helix (English ivy). The order Apiales is placed within the asterid group of eudicots as circumscribed by the APG III system. Within the asterids, Apiales belongs to an unranked group called the campanulids, and within the campanulids, it belongs to a clade known in phylogenetic nomenclature as Apiidae. In 2010, a subclade of Apiidae named Dipsapiidae was defined to consist of the three orders: Apiales, Paracryphiales, and Dipsacales. Taxonomy Under the Cronquist system, only the Apiaceae and Araliaceae were included here, and the restricted order was placed among the rosids rather than the asterids. The Pittosporaceae were placed within the Rosales, and many of the other forms within the family Cornaceae. Pennantia was in the family Icacinaceae. In the classification system of Dahlgren the families Apiaceae and Araliaceae were placed in the order Ariales, in the superorder Araliiflorae (also called Aralianae). The present understanding of the Apiales is fairly recent and is based upon comparison of DNA sequences by phylogenetic methods. The circumscriptions of some of the families have changed. In 2009, one of the subfamilies of Araliaceae was shown to be polyphyletic. Gynoecia The largest and obviously closely related families of Apiales are Araliaceae, Myodocarpaceae and Apiaceae, which resemble each other in the structure of their gynoecia. In this respect however, the Pittosporaceae is notably distinct from them. Typical syncarpous gynoecia exhibit four vertical zones, determined by the extent of fusion of the carpels. In most plants the synascidiate (i.e. "united bottle-shaped") and symplicate zones are fertile and bear the ovules. Each of the first three families possess mainly bi- or multilocular ovaries in a gynoecium with a long synascidiate, but very short symplicate zone, where the ovules are inserted at their transition, the so-called cross-zone (or "Querzone"). In gynoecia of the Pittosporaceae, the symplicate is much longer than the synascidiate zone, and the ovules are arranged along the first. Members of the latter family consequently have unilocular ovaries with a single cavity between adjacent carpels. References Angiosperm orders Taxa named by Takenoshin Nakai

Apiales The Apiales are an order of flowering plants. The families are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation and in particular, the Torriceliaceae may be divided. Under this definition, well-known members include carrots, celery, parsley, and Hedera helix (English ivy). The order Apiales is placed within the asterid group of eudicots as circumscribed by the APG III system. Within the asterids, Apiales belongs to an unranked group called the campanulids, and within the campanulids, it belongs to a clade known in phylogenetic nomenclature as Apiidae. In 2010, a subclade of Apiidae named Dipsapiidae was defined to consist of the three orders: Apiales, Paracryphiales, and Dipsacales.

Asterales Asterales is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the Lobelia deckenii, the giant lobelia, and Dendrosenecio, giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide inulin, a nutrient storage molecule used instead of starch; and unique stamen morphology. The stamens are usually found around the style, either aggregated densely or fused into a tube, probably an adaptation in association with the plunger (brush; or secondary) pollination that is common among the families of the order, wherein pollen is collected and stored on the length of the pistil. Taxonomy The name and order Asterales is botanically venerable, dating back to at least 1926 in the Hutchinson system of plant taxonomy when it contained only five families, of which only two are retained in the APG III classification. Under the Cronquist system of taxonomic classification of flowering plants, Asteraceae was the only family in the group, but newer systems (such as APG II and APG III) have expanded it to 11. In the classification system of Dahlgren the Asterales were in the superorder Asteriflorae (also called Asteranae). The order Asterales currently includes 11 families, the largest of which are the Asteraceae, with about 25,000 species, and the Campanulaceae ("bellflowers"), with about 2,000 species. The remaining families count together for less than 1500 species. The two large families are cosmopolitan, with many of their species found in the Northern Hemisphere, and the smaller families are usually confined to Australia and the adjacent areas, or sometimes South America. Only the Asteraceae have composite flower heads; the other families do not, but share other characteristics such as storage of inulin that define the 11 families as more closely related to each other than to other plant families or orders such as the rosids. The phylogenetic tree according to APG III for the Campanulid clade is as below. Biogeography The core Asterales are Stylidiaceae (six genera), APA clade (Alseuosmiaceae, Phellinaceae and Argophyllaceae, together 7 genera), MGCA clade (Menyanthaceae, Goodeniaceae, Calyceraceae, in total twenty genera), and Asteraceae (about sixteen hundred genera). Other Asterales are Rousseaceae (four genera), Campanulaceae (eighty four genera) and Pentaphragmataceae (one genus). All Asterales families are represented in the Southern Hemisphere; however, Asteraceae and Campanulaceae are cosmopolitan and Menyanthaceae nearly so.

Evolution Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America. Less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub. Because all clades are represented in the southern hemisphere but many not in the northern hemisphere, it is natural to conjecture that there is a common southern origin to them. Asterales are angiosperms, flowering plants that appeared about 140 million years ago. The Asterales order probably originated in the Cretaceous (145 – 66 Mya) on the supercontinent Gondwana which broke up from 184 – 80 Mya, forming the area that is now Australia, South America, Africa, India and Antarctica. Asterales contain about 14% of eudicot diversity. From an analysis of relationships and diversities within the Asterales and with their superorders, estimates of the age of the beginning of the Asterales have been made, which range from 116 Mya to 82Mya. However few fossils have been found, of the Menyanthaceae-Asteraceae clade in the Oligocene, about 29 Mya. Fossil evidence of the Asterales is rare and belongs to rather recent epochs, so the precise estimation of the order's age is quite difficult. An Oligocene (34 – 23 Mya) pollen is known for Asteraceae and Goodeniaceae, and seeds from Oligocene and Miocene (23 – 5.3 Mya) are known for Menyanthaceae and Campanulaceae respectively. Economic importance The Asterales, by dint of being a super-set of the family Asteraceae, include some species grown for food, including the sunflower (Helianthus annuus), lettuce (Lactuca sativa) and chicory (Cichorium). Many are also used as spices and traditional medicines. Asterales are common plants and have many known uses. For example, pyrethrum (derived from Old World members of the genus Chrysanthemum) is a natural insecticide with minimal environmental impact. Wormwood, derived from a genus that includes the sagebrush, is used as a source of flavoring for absinthe, a bitter classical liquor of European origin. References Citations General references W. S.

Asteroid An asteroid is a minor planet of the inner Solar System. Historically, these terms have been applied to any astronomical object orbiting the Sun that did not resolve into a disc in a telescope and was not observed to have characteristics of an active comet such as a tail. As minor planets in the outer Solar System were discovered that were found to have volatile-rich surfaces similar to comets, these came to be distinguished from the objects found in the main asteroid belt. Thus the term "asteroid" now generally refers to the minor planets of the inner Solar System, including those co-orbital with Jupiter. Larger asteroids are often called planetoids. Overview Millions of asteroids exist: many are shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. The vast majority of known asteroids orbit within the main asteroid belt located between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbon-rich, metallic, and silicate (stony) compositions, respectively. The sizes of asteroids varies greatly; the largest, Ceres, is almost across and massive enough to qualify as a dwarf planet. Asteroids are somewhat arbitrarily differentiated from comets and meteoroids. In the case of comets, the difference is one of composition: while asteroids are mainly composed of mineral and rock, comets are primarily composed of dust and ice. Furthermore, asteroids formed closer to the sun, preventing the development of cometary ice. The difference between asteroids and meteoroids is mainly one of size: meteoroids have a diameter of one meter or less, whereas asteroids have a diameter of greater than one meter. Finally, meteoroids can be composed of either cometary or asteroidal materials. Only one asteroid, 4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye, and this is only in very dark skies when it is favorably positioned. Rarely, small asteroids passing close to Earth may be visible to the naked eye for a short time. , the Minor Planet Center had data on 930,000 minor planets in the inner and outer Solar System, of which about 545,000 had enough information to be given numbered designations. The United Nations declared 30 June as International Asteroid Day to educate the public about asteroids. The date of International Asteroid Day commemorates the anniversary of the Tunguska asteroid impact over Siberia, Russian Federation, on 30 June 1908. In April 2018, the B612 Foundation reported "It is 100 percent certain we'll be hit [by a devastating asteroid], but we're not 100 percent sure when." Also in 2018, physicist Stephen Hawking, in his final book Brief Answers to the Big Questions, considered an asteroid collision to be the biggest threat to the planet.

In June 2018, the US National Science and Technology Council warned that America is unprepared for an asteroid impact event, and has developed and released the "National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. According to expert testimony in the United States Congress in 2013, NASA would require at least five years of preparation before a mission to intercept an asteroid could be launched. Discovery The first asteroid to be discovered, Ceres, was originally considered to be a new planet. This was followed by the discovery of other similar bodies, which, with the equipment of the time, appeared to be points of light, like stars, showing little or no planetary disc, though readily distinguishable from stars due to their apparent motions. This prompted the astronomer Sir William Herschel to propose the term "asteroid", coined in Greek as ἀστεροειδής, or asteroeidēs, meaning 'star-like, star-shaped', and derived from the Ancient Greek astēr 'star, planet'. In the early second half of the nineteenth century, the terms "asteroid" and "planet" (not always qualified as "minor") were still used interchangeably. Discovery timeline: 10 by 1849 1 Ceres, 1801 2 Pallas 1802 3 Juno 1804 4 Vesta 1807 5 Astraea 1845 in 1846, planet Neptune was discovered 6 Hebe July 1847 7 Iris August 1847 8 Flora October 1847 9 Metis 25 April 1848 10 Hygiea 12 April 1849 tenth asteroid discovered 100 asteroids by 1868 1,000 by 1921 10,000 by 1989 100,000 by 2005 1,000,000 by 2020 Historical methods Asteroid discovery methods have dramatically improved over the past two centuries. In the last years of the 18th century, Baron Franz Xaver von Zach organized a group of 24 astronomers to search the sky for the missing planet predicted at about 2.8 AU from the Sun by the Titius-Bode law, partly because of the discovery, by Sir William Herschel in 1781, of the planet Uranus at the distance predicted by the law. This task required that hand-drawn sky charts be prepared for all stars in the zodiacal band down to an agreed-upon limit of faintness. On subsequent nights, the sky would be charted again and any moving object would, hopefully, be spotted. The expected motion of the missing planet was about 30 seconds of arc per hour, readily discernible by observers. The first object, Ceres, was not discovered by a member of the group, but rather by accident in 1801 by Giuseppe Piazzi, director of the observatory of Palermo in Sicily. He discovered a new star-like object in Taurus and followed the displacement of this object during several nights. Later that year, Carl Friedrich Gauss used these observations to calculate the orbit of this unknown object, which was found to be between the planets Mars and Jupiter. Piazzi named it after Ceres, the Roman goddess of agriculture. Three other asteroids (2 Pallas, 3 Juno, and 4 Vesta) were discovered over the next few years, with Vesta found in 1807.

After eight more years of fruitless searches, most astronomers assumed that there were no more and abandoned any further searches. However, Karl Ludwig Hencke persisted, and began searching for more asteroids in 1830. Fifteen years later, he found 5 Astraea, the first new asteroid in 38 years. He also found 6 Hebe less than two years later. After this, other astronomers joined in the search and at least one new asteroid was discovered every year after that (except the wartime year 1945). Notable asteroid hunters of this early era were J.R. Hind, A. de Gasparis, R. Luther, H.M.S. Goldschmidt, J. Chacornac, J. Ferguson, N.R. Pogson, E.W. Tempel, J.C. Watson, C.H.F. Peters, A. Borrelly, J. Palisa, the Henry brothers and A. Charlois. In 1891, Max Wolf pioneered the use of astrophotography to detect asteroids, which appeared as short streaks on long-exposure photographic plates. This dramatically increased the rate of detection compared with earlier visual methods: Wolf alone discovered 248 asteroids, beginning with 323 Brucia, whereas only slightly more than 300 had been discovered up to that point. It was known that there were many more, but most astronomers did not bother with them, some calling them "vermin of the skies", a phrase variously attributed to E. Suess and E. Weiss. Even a century later, only a few thousand asteroids were identified, numbered and named. Manual methods of the 1900s and modern reporting Until 1998, asteroids were discovered by a four-step process. First, a region of the sky was photographed by a wide-field telescope, or astrograph. Pairs of photographs were taken, typically one hour apart. Multiple pairs could be taken over a series of days. Second, the two films or plates of the same region were viewed under a stereoscope. Any body in orbit around the Sun would move slightly between the pair of films. Under the stereoscope, the image of the body would seem to float slightly above the background of stars. Third, once a moving body was identified, its location would be measured precisely using a digitizing microscope. The location would be measured relative to known star locations. These first three steps do not constitute asteroid discovery: the observer has only found an apparition, which gets a provisional designation, made up of the year of discovery, a letter representing the half-month of discovery, and finally a letter and a number indicating the discovery's sequential number (example: ). The last step of discovery is to send the locations and time of observations to the Minor Planet Center, where computer programs determine whether an apparition ties together earlier apparitions into a single orbit. If so, the object receives a catalogue number and the observer of the first apparition with a calculated orbit is declared the discoverer, and granted the honor of naming the object subject to the approval of the International Astronomical Union. Computerized methods There is increasing interest in identifying asteroids whose orbits cross Earth's, and that could, given enough time, collide with Earth (see Earth-crosser asteroids).

The three most important groups of near-Earth asteroids are the Apollos, Amors, and Atens. Various asteroid deflection strategies have been proposed, as early as the 1960s. The near-Earth asteroid 433 Eros had been discovered as long ago as 1898, and the 1930s brought a flurry of similar objects. In order of discovery, these were: 1221 Amor, 1862 Apollo, 2101 Adonis, and finally 69230 Hermes, which approached within 0.005 AU of Earth in 1937. Astronomers began to realize the possibilities of Earth impact. Two events in later decades increased the alarm: the increasing acceptance of the Alvarez hypothesis that an impact event resulted in the Cretaceous–Paleogene extinction, and the 1994 observation of Comet Shoemaker-Levy 9 crashing into Jupiter. The U.S. military also declassified the information that its military satellites, built to detect nuclear explosions, had detected hundreds of upper-atmosphere impacts by objects ranging from one to ten meters across. All these considerations helped spur the launch of highly efficient surveys that consist of charge-coupled device (CCD) cameras and computers directly connected to telescopes. , it was estimated that 89% to 96% of near-Earth asteroids one kilometer or larger in diameter had been discovered. A list of teams using such systems includes: Lincoln Near-Earth Asteroid Research (LINEAR) Near-Earth Asteroid Tracking (NEAT) Spacewatch Lowell Observatory Near-Earth-Object Search (LONEOS) Catalina Sky Survey (CSS) Pan-STARRS NEOWISE Asteroid Terrestrial-impact Last Alert System (ATLAS) Campo Imperatore Near-Earth Object Survey (CINEOS) Japanese Spaceguard Association Asiago-DLR Asteroid Survey (ADAS) , the LINEAR system alone has discovered 147,132 asteroids. Among all the surveys, 19,266 near-Earth asteroids have been discovered including almost 900 more than in diameter. Terminology Traditionally, small bodies orbiting the Sun were classified as comets, asteroids, or meteoroids, with anything smaller than one meter across being called a meteoroid. Beech and Steel's 1995 paper proposed a meteoroid definition including size limits. The term "asteroid", from the Greek word for "star-like", never had a formal definition, with the broader term minor planet being preferred by the International Astronomical Union. However, following the discovery of asteroids below ten meters in size, Rubin and Grossman's 2010 paper revised the previous definition of meteoroid to objects between 10 µm and 1 meter in size in order to maintain the distinction between asteroids and meteoroids. The smallest asteroids discovered (based on absolute magnitude H) are with and with both with an estimated size of about 1 meter. In 2006, the term "small Solar System body" was also introduced to cover both most minor planets and comets. Other languages prefer "planetoid" (Greek for "planet-like"), and this term is occasionally used in English especially for larger minor planets such as the dwarf planets as well as an alternative for asteroids since they are not star-like. The word "planetesimal" has a similar meaning, but refers specifically to the small building blocks of the planets that existed when the Solar System was forming. The term "planetule" was coined by the geologist William Daniel Conybeare to describe minor planets, but is not in common use.

The three largest objects in the asteroid belt, Ceres, Pallas, and Vesta, grew to the stage of protoplanets. Ceres is a dwarf planet, the only one in the inner Solar System. When found, asteroids were seen as a class of objects distinct from comets, and there was no unified term for the two until "small Solar System body" was coined in 2006. The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near-surface ices by solar radiation. A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity. Conversely, some (perhaps all) comets are eventually depleted of their surface volatile ices and become asteroid-like. A further distinction is that comets typically have more eccentric orbits than most asteroids; most "asteroids" with notably eccentric orbits are probably dormant or extinct comets. For almost two centuries, from the discovery of Ceres in 1801 until the discovery of the first centaur, Chiron in 1977, all known asteroids spent most of their time at or within the orbit of Jupiter, though a few such as Hidalgo ventured far beyond Jupiter for part of their orbit. Those located between the orbits of Mars and Jupiter were known for many years simply as The Asteroids. When astronomers started finding more small bodies that permanently resided further out than Jupiter, now called centaurs, they numbered them among the traditional asteroids, though there was debate over whether they should be considered asteroids or as a new type of object. Then, when the first trans-Neptunian object (other than Pluto), Albion, was discovered in 1992, and especially when large numbers of similar objects started turning up, new terms were invented to sidestep the issue: Kuiper-belt object, trans-Neptunian object, scattered-disc object, and so on. These inhabit the cold outer reaches of the Solar System where ices remain solid and comet-like bodies are not expected to exhibit much cometary activity; if centaurs or trans-Neptunian objects were to venture close to the Sun, their volatile ices would sublimate, and traditional approaches would classify them as comets and not asteroids. The innermost of these are the Kuiper-belt objects, called "objects" partly to avoid the need to classify them as asteroids or comets. They are thought to be predominantly comet-like in composition, though some may be more akin to asteroids. Furthermore, most do not have the highly eccentric orbits associated with comets, and the ones so far discovered are larger than traditional comet nuclei. (The much more distant Oort cloud is hypothesized to be the main reservoir of dormant comets.) Other recent observations, such as the analysis of the cometary dust collected by the Stardust probe, are increasingly blurring the distinction between comets and asteroids, suggesting "a continuum between asteroids and comets" rather than a sharp dividing line. The minor planets beyond Jupiter's orbit are sometimes also called "asteroids", especially in popular presentations.

However, it is becoming increasingly common for the term "asteroid" to be restricted to minor planets of the inner Solar System. Therefore, this article will restrict itself for the most part to the classical asteroids: objects of the asteroid belt, Jupiter trojans, and near-Earth objects. When the IAU introduced the class small Solar System bodies in 2006 to include most objects previously classified as minor planets and comets, they created the class of dwarf planets for the largest minor planets – those that have enough mass to have become ellipsoidal under their own gravity. According to the IAU, "the term 'minor planet' may still be used, but generally, the term 'Small Solar System Body' will be preferred." Currently only the largest object in the asteroid belt, Ceres, at about across, has been placed in the dwarf planet category. Formation It is thought that planetesimals in the asteroid belt evolved much like the rest of the solar nebula until Jupiter neared its current mass, at which point excitation from orbital resonances with Jupiter ejected over 99% of planetesimals in the belt. Simulations and a discontinuity in spin rate and spectral properties suggest that asteroids larger than approximately in diameter accreted during that early era, whereas smaller bodies are fragments from collisions between asteroids during or after the Jovian disruption. Ceres and Vesta grew large enough to melt and differentiate, with heavy metallic elements sinking to the core, leaving rocky minerals in the crust. In the Nice model, many Kuiper-belt objects are captured in the outer asteroid belt, at distances greater than 2.6 AU. Most were later ejected by Jupiter, but those that remained may be the D-type asteroids, and possibly include Ceres. Distribution within the Solar System Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System. Their orbits are perturbed by the gravity of other bodies in the Solar System and by the Yarkovsky effect. Significant populations include: Asteroid belt The majority of known asteroids orbit within the asteroid belt between the orbits of Mars and Jupiter, generally in relatively low-eccentricity (i.e. not very elongated) orbits. This belt is now estimated to contain between 1.1 and 1.9 million asteroids larger than in diameter, and millions of smaller ones. These asteroids may be remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the Solar System was prevented by large gravitational perturbations by Jupiter. Trojans Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two Lagrangian points of stability, L4 and L5, which lie 60° ahead of and behind the larger body. The most significant population of trojans are the Jupiter trojans. Although fewer Jupiter trojans have been discovered (), it is thought that they are as numerous as the asteroids in the asteroid belt.

This belt is now estimated to contain between 1.1 and 1.9 million asteroids larger than in diameter, and millions of smaller ones. These asteroids may be remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the Solar System was prevented by large gravitational perturbations by Jupiter. Trojans Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two Lagrangian points of stability, L4 and L5, which lie 60° ahead of and behind the larger body. The most significant population of trojans are the Jupiter trojans. Although fewer Jupiter trojans have been discovered (), it is thought that they are as numerous as the asteroids in the asteroid belt.

Trojans have been found in the orbits of other planets, including Venus, Earth, Mars, Uranus, and Neptune. Near-Earth asteroids Near-Earth asteroids, or NEAs, are asteroids that have orbits that pass close to that of Earth. Asteroids that actually cross Earth's orbital path are known as Earth-crossers. , 14,464 near-Earth asteroids are known and approximately 900–1,000 have a diameter of over one kilometer. Characteristics Size distribution Asteroids vary greatly in size, from almost for the largest down to rocks just 1 meter across. The three largest are very much like miniature planets: they are roughly spherical, have at least partly differentiated interiors, and are thought to be surviving protoplanets. The vast majority, however, are much smaller and are irregularly shaped; they are thought to be either battered planetesimals or fragments of larger bodies. The dwarf planet Ceres is by far the largest asteroid, with a diameter of . The next largest are 4 Vesta and 2 Pallas, both with diameters of just over . Vesta is the only main-belt asteroid that can, on occasion, be visible to the naked eye. On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis. The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be in the range of , about 4% of the mass of the Moon. Of this, Ceres comprises , about a third of the total. Adding in the next three most massive objects, Vesta (9%), Pallas (7%), and Hygiea (3%), brings this figure up to half, whereas the three most-massive asteroids after that, 511 Davida (1.2%), 704 Interamnia (1.0%), and 52 Europa (0.9%), constitute only another 3%. The number of asteroids increases rapidly as their individual masses decrease. The number of asteroids decreases markedly with size. Although this generally follows a power law, there are 'bumps' at and , where more asteroids than expected from a logarithmic distribution are found. Largest asteroids Although their location in the asteroid belt excludes them from planet status, the three largest objects, Ceres, Vesta, and Pallas, are intact protoplanets that share many characteristics common to planets, and are atypical compared to the majority of irregularly shaped asteroids. The fourth-largest asteroid, Hygiea, appears nearly spherical although it may have an undifferentiated interior, like the majority of asteroids. Between them, the four largest asteroids constitute half the mass of the asteroid belt. Ceres is the only asteroid that appears to be plastic shape under its own gravity and hence the only one that is a likely dwarf planet. It has a much higher absolute magnitude than the other asteroids, of around 3.32, and may possess a surface layer of ice. Like the planets, Ceres is differentiated: it has a crust, a mantle and a core. No meteorites from Ceres have been found on Earth.

Like the planets, Ceres is differentiated: it has a crust, a mantle and a core. No meteorites from Ceres have been found on Earth.

Vesta, too, has a differentiated interior, though it formed inside the Solar System's frost line, and so is devoid of water; its composition is mainly of basaltic rock with minerals such as olivine. Aside from the large crater at its southern pole, Rheasilvia, Vesta also has an ellipsoidal shape. Vesta is the parent body of the Vestian family and other V-type asteroids, and is the source of the HED meteorites, which constitute 5% of all meteorites on Earth. Pallas is unusual in that, like Uranus, it rotates on its side, with its axis of rotation tilted at high angles to its orbital plane. Its composition is similar to that of Ceres: high in carbon and silicon, and perhaps partially differentiated. Pallas is the parent body of the Palladian family of asteroids. Hygiea is the largest carbonaceous asteroid and, unlike the other largest asteroids, lies relatively close to the plane of the ecliptic. It is the largest member and presumed parent body of the Hygiean family of asteroids. Because there is no sufficiently large crater on the surface to be the source of that family, as there is on Vesta, it is thought that Hygiea may have been completely disrupted in the collision that formed the Hygiean family and recoalesced after losing a bit less than 2% of its mass. Observations taken with the Very Large Telescope's SPHERE imager in 2017 and 2018, and announced in late 2019, revealed that Hygiea has a nearly spherical shape, which is consistent both with it being in hydrostatic equilibrium (and thus a dwarf planet), or formerly being in hydrostatic equilibrium, or with being disrupted and recoalescing. Rotation Measurements of the rotation rates of large asteroids in the asteroid belt show that there is an upper limit. Very few asteroids with a diameter larger than 100 meters have a rotation period smaller than 2.2 hours. For asteroids rotating faster than approximately this rate, the inertial force at the surface is greater than the gravitational force, so any loose surface material would be flung out. However, a solid object should be able to rotate much more rapidly. This suggests that most asteroids with a diameter over 100 meters are rubble piles formed through the accumulation of debris after collisions between asteroids. Composition The physical composition of asteroids is varied and in most cases poorly understood. Ceres appears to be composed of a rocky core covered by an icy mantle, where Vesta is thought to have a nickel-iron core, olivine mantle, and basaltic crust. 10 Hygiea, however, which appears to have a uniformly primitive composition of carbonaceous chondrite, is thought to be the largest undifferentiated asteroid, though it may be a differentiated asteroid that was globally disrupted by an impact and then reassembled. Other asteroids appear to be the remnant cores or mantles of proto-planets, high in rock and metal Most small asteroids are thought to be piles of rubble held together loosely by gravity, though the largest are probably solid.

Some asteroids have moons or are co-orbiting binaries: Rubble piles, moons, binaries, and scattered asteroid families are thought to be the results of collisions that disrupted a parent asteroid, or, possibly, a planet. In the main asteroid belt, there appear to be two primary populations of asteroid: a dark, volatile-rich population, consisting of the C-type and P-type asteroids, with albedos less that 0.10 and densities under , and a dense, volatile-poor population, consisting of the S-type and M-type asteroids, with albedos over 0.15 and densities greater than 2.7. Within these populations, larger asteroids are denser, presumably due to compression. There appears to be minimal macro-porosity (interstitial vacuum) in the score of asteroids with masses greater than . Asteroids contain traces of amino acids and other organic compounds, and some speculate that asteroid impacts may have seeded the early Earth with the chemicals necessary to initiate life, or may have even brought life itself to Earth (also see panspermia). In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting DNA and RNA components (adenine, guanine and related organic molecules) may have been formed on asteroids and comets in outer space. Composition is calculated from three primary sources: albedo, surface spectrum, and density. The last can only be determined accurately by observing the orbits of moons the asteroid might have. So far, every asteroid with moons has turned out to be a rubble pile, a loose conglomeration of rock and metal that may be half empty space by volume. The investigated asteroids are as large as 280 km in diameter, and include 121 Hermione (268×186×183 km), and 87 Sylvia (384×262×232 km). Only half a dozen asteroids are larger than 87 Sylvia, though none of them have moons. The fact that such large asteroids as Sylvia may be rubble piles, presumably due to disruptive impacts, has important consequences for the formation of the Solar System: Computer simulations of collisions involving solid bodies show them destroying each other as often as merging, but colliding rubble piles are more likely to merge. This means that the cores of the planets could have formed relatively quickly. On 7 October 2009, the presence of water ice was confirmed on the surface of 24 Themis using NASA's Infrared Telescope Facility. The surface of the asteroid appears completely covered in ice. As this ice layer is sublimating, it may be getting replenished by a reservoir of ice under the surface. Organic compounds were also detected on the surface. Scientists hypothesize that some of the first water brought to Earth was delivered by asteroid impacts after the collision that produced the Moon. The presence of ice on 24 Themis supports this theory. In October 2013, water was detected on an extrasolar body for the first time, on an asteroid orbiting the white dwarf GD 61.

On 22 January 2014, European Space Agency (ESA) scientists reported the detection, for the first definitive time, of water vapor on Ceres, the largest object in the asteroid belt. The detection was made by using the far-infrared abilities of the Herschel Space Observatory. The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids." In May 2016, significant asteroid data arising from the Wide-field Infrared Survey Explorer and NEOWISE missions have been questioned. Although the early original criticism had not undergone peer review, a more recent peer-reviewed study was subsequently published. In November 2019, scientists reported detecting, for the first time, sugar molecules, including ribose, in meteorites, suggesting that chemical processes on asteroids can produce some fundamentally essential bio-ingredients important to life, and supporting the notion of an RNA world prior to a DNA-based origin of life on Earth, and possibly, as well, the notion of panspermia. Acfer 049, a meteorite discovered in Algeria in 1990, was shown in 2019 to have ice fossils inside it – the first direct evidence of water ice in the composition of asteroids. Findings have shown that solar winds can react with the oxygen in the upper layer of the asteroids and create water. It has been estimated that every cubic metre of irradiated rock could contain up to 20 litres. Surface features Most asteroids outside the "big four" (Ceres, Pallas, Vesta, and Hygiea) are likely to be broadly similar in appearance, if irregular in shape. 50 km (31 mi) 253 Mathilde is a rubble pile saturated with craters with diameters the size of the asteroid's radius, and Earth-based observations of 300 km (186 mi) 511 Davida, one of the largest asteroids after the big four, reveal a similarly angular profile, suggesting it is also saturated with radius-size craters. Medium-sized asteroids such as Mathilde and 243 Ida that have been observed up close also reveal a deep regolith covering the surface. Of the big four, Pallas and Hygiea are practically unknown. Vesta has compression fractures encircling a radius-size crater at its south pole but is otherwise a spheroid. Ceres seems quite different in the glimpses Hubble has provided, with surface features that are unlikely to be due to simple craters and impact basins, but details will be expanded with the Dawn spacecraft, which entered Ceres orbit on 6 March 2015. Color Asteroids become darker and redder with age due to space weathering. However evidence suggests most of the color change occurs rapidly, in the first hundred thousand years, limiting the usefulness of spectral measurement for determining the age of asteroids. Classification Asteroids are commonly categorized according to two criteria: the characteristics of their orbits, and features of their reflectance spectrum. Orbital classification Many asteroids have been placed in groups and families based on their orbital characteristics.

Ceres seems quite different in the glimpses Hubble has provided, with surface features that are unlikely to be due to simple craters and impact basins, but details will be expanded with the Dawn spacecraft, which entered Ceres orbit on 6 March 2015. Color Asteroids become darker and redder with age due to space weathering. However evidence suggests most of the color change occurs rapidly, in the first hundred thousand years, limiting the usefulness of spectral measurement for determining the age of asteroids. Classification Asteroids are commonly categorized according to two criteria: the characteristics of their orbits, and features of their reflectance spectrum. Orbital classification Many asteroids have been placed in groups and families based on their orbital characteristics.

Apart from the broadest divisions, it is customary to name a group of asteroids after the first member of that group to be discovered. Groups are relatively loose dynamical associations, whereas families are tighter and result from the catastrophic break-up of a large parent asteroid sometime in the past. Families are more common and easier to identify within the main asteroid belt, but several small families have been reported among the Jupiter trojans. Main belt families were first recognized by Kiyotsugu Hirayama in 1918 and are often called Hirayama families in his honor. About 30–35% of the bodies in the asteroid belt belong to dynamical families each thought to have a common origin in a past collision between asteroids. A family has also been associated with the plutoid dwarf planet . Quasi-satellites and horseshoe objects Some asteroids have unusual horseshoe orbits that are co-orbital with Earth or some other planet. Examples are 3753 Cruithne and . The first instance of this type of orbital arrangement was discovered between Saturn's moons Epimetheus and Janus. Sometimes these horseshoe objects temporarily become quasi-satellites for a few decades or a few hundred years, before returning to their earlier status. Both Earth and Venus are known to have quasi-satellites. Such objects, if associated with Earth or Venus or even hypothetically Mercury, are a special class of Aten asteroids. However, such objects could be associated with outer planets as well. Spectral classification In 1975, an asteroid taxonomic system based on color, albedo, and spectral shape was developed by Chapman, Morrison, and Zellner. These properties are thought to correspond to the composition of the asteroid's surface material. The original classification system had three categories: C-types for dark carbonaceous objects (75% of known asteroids), S-types for stony (silicaceous) objects (17% of known asteroids) and U for those that did not fit into either C or S. This classification has since been expanded to include many other asteroid types. The number of types continues to grow as more asteroids are studied. The two most widely used taxonomies now used are the Tholen classification and SMASS classification. The former was proposed in 1984 by David J. Tholen, and was based on data collected from an eight-color asteroid survey performed in the 1980s. This resulted in 14 asteroid categories. In 2002, the Small Main-Belt Asteroid Spectroscopic Survey resulted in a modified version of the Tholen taxonomy with 24 different types. Both systems have three broad categories of C, S, and X asteroids, where X consists of mostly metallic asteroids, such as the M-type. There are also several smaller classes. The proportion of known asteroids falling into the various spectral types does not necessarily reflect the proportion of all asteroids that are of that type; some types are easier to detect than others, biasing the totals. Problems Originally, spectral designations were based on inferences of an asteroid's composition. However, the correspondence between spectral class and composition is not always very good, and a variety of classifications are in use.

This has led to significant confusion. Although asteroids of different spectral classifications are likely to be composed of different materials, there are no assurances that asteroids within the same taxonomic class are composed of the same (or similar) materials. Naming A newly discovered asteroid is given a provisional designation (such as ) consisting of the year of discovery and an alphanumeric code indicating the half-month of discovery and the sequence within that half-month. Once an asteroid's orbit has been confirmed, it is given a number, and later may also be given a name (e.g. ). The formal naming convention uses parentheses around the number – e.g. (433) Eros – but dropping the parentheses is quite common. Informally, it is common to drop the number altogether, or to drop it after the first mention when a name is repeated in running text. In addition, names can be proposed by the asteroid's discoverer, within guidelines established by the International Astronomical Union. Symbols The first asteroids to be discovered were assigned iconic symbols like the ones traditionally used to designate the planets. By 1855 there were two dozen asteroid symbols, which often occurred in multiple variants. In 1851, after the fifteenth asteroid (Eunomia) had been discovered, Johann Franz Encke made a major change in the upcoming 1854 edition of the Berliner Astronomisches Jahrbuch (BAJ, Berlin Astronomical Yearbook). He introduced a disk (circle), a traditional symbol for a star, as the generic symbol for an asteroid. The circle was then numbered in order of discovery to indicate a specific asteroid (although he assigned ① to the fifth, Astraea, while continuing to designate the first four only with their existing iconic symbols). The numbered-circle convention was quickly adopted by astronomers, and the next asteroid to be discovered (16 Psyche, in 1852) was the first to be designated in that way at the time of its discovery. However, Psyche was given an iconic symbol as well, as were a few other asteroids discovered over the next few years (see chart above). 20 Massalia was the first asteroid that was not assigned an iconic symbol, and no iconic symbols were created after the 1855 discovery of 37 Fides. That year Astraea's number was increased to ⑤, but the first four asteroids, Ceres to Vesta, were not listed by their numbers until the 1867 edition. The circle was soon abbreviated to a pair of parentheses, which were easier to typeset and sometimes omitted altogether over the next few decades, leading to the modern convention. Exploration Until the age of space travel, objects in the asteroid belt were merely pinpricks of light in even the largest telescopes and their shapes and terrain remained a mystery. The best modern ground-based telescopes and the Earth-orbiting Hubble Space Telescope can resolve a small amount of detail on the surfaces of the largest asteroids, but even these mostly remain little more than fuzzy blobs.

Limited information about the shapes and compositions of asteroids can be inferred from their light curves (their variation in brightness as they rotate) and their spectral properties, and asteroid sizes can be estimated by timing the lengths of star occultations (when an asteroid passes directly in front of a star). Radar imaging can yield good information about asteroid shapes and orbital and rotational parameters, especially for near-Earth asteroids. In terms of delta-v and propellant requirements, NEOs are more easily accessible than the Moon. The first close-up photographs of asteroid-like objects were taken in 1971, when the Mariner 9 probe imaged Phobos and Deimos, the two small moons of Mars, which are probably captured asteroids. These images revealed the irregular, potato-like shapes of most asteroids, as did later images from the Voyager probes of the small moons of the gas giants. The first true asteroid to be photographed in close-up was 951 Gaspra in 1991, followed in 1993 by 243 Ida and its moon Dactyl, all of which were imaged by the Galileo probe en route to Jupiter. The first dedicated asteroid probe was NEAR Shoemaker, which photographed 253 Mathilde in 1997, before entering into orbit around 433 Eros, finally landing on its surface in 2001. Other asteroids briefly visited by spacecraft en route to other destinations include 9969 Braille (by Deep Space 1 in 1999), and 5535 Annefrank (by Stardust in 2002). From September to November 2005, the Japanese Hayabusa probe studied 25143 Itokawa in detail and was plagued with difficulties, but returned samples of its surface to Earth on 13 June 2010. The European Rosetta probe (launched in 2004) flew by 2867 Šteins in 2008 and 21 Lutetia, the third-largest asteroid visited to date, in 2010. In September 2007, NASA launched the Dawn spacecraft, which orbited 4 Vesta from July 2011 to September 2012, and has been orbiting the dwarf planet 1 Ceres since 2015. 4 Vesta is the second-largest asteroid visited to date. On 13 December 2012, China's lunar orbiter Chang'e 2 flew within of the asteroid 4179 Toutatis on an extended mission. The Japan Aerospace Exploration Agency (JAXA) launched the Hayabusa2 probe in December 2014, and plans to return samples from 162173 Ryugu in December 2020. In June 2018, the US National Science and Technology Council warned that America is unprepared for an asteroid impact event, and has developed and released the "National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. In September 2016, NASA launched the OSIRIS-REx sample return mission to asteroid 101955 Bennu, which it reached in December 2018. On May 10 2021, the probe departed the asteroid with a sample from its surface, and is expected to return to Earth on September 24 2023. Planned and future missions In early 2013, NASA announced the planning stages of a mission to capture a near-Earth asteroid and move it into lunar orbit where it could possibly be visited by astronauts and later impacted into the Moon.

On 19 June 2014, NASA reported that asteroid 2011 MD was a prime candidate for capture by a robotic mission, perhaps in the early 2020s. It has been suggested that asteroids might be used as a source of materials that may be rare or exhausted on Earth (asteroid mining), or materials for constructing space habitats (see Colonization of the asteroids). Materials that are heavy and expensive to launch from Earth may someday be mined from asteroids and used for space manufacturing and construction. In the U.S. Discovery program the Psyche spacecraft proposal to 16 Psyche and Lucy spacecraft to Jupiter trojans made it to the semi-finalist stage of mission selection. In January 2017, Lucy and Psyche mission were both selected as NASA's Discovery Program missions 13 and 14 respectively.

Allocution An allocution, or allocutus, is a formal statement made to the court by the defendant who has been found guilty prior to being sentenced. It is part of the criminal procedure in some jurisdictions using common law. Concept An allocution allows the defendant to explain why the sentence should be lenient. In plea bargains, an allocution may be required of the defendant. The defendant explicitly admits specifically and in detail the actions and their reasons in exchange for a reduced sentence. In principle, that removes any doubt as to the exact nature of the defendant's guilt in the matter. The term "allocution" is used generally only in jurisdictions in the United States, but there are vaguely similar processes in other common law countries. In many other jurisdictions, it is for the defense lawyer to mitigate on their client's behalf, and the defendant rarely has the opportunity to speak. The right of victims to speak at sentencing is also sometimes referred to as allocution. Australia In Australia, the term allocutus is used by the Clerk of Arraigns or another formal associate of the Court. It is generally phrased as, "Prisoner at the Bar, you have been found Guilty by a jury of your peers of the offense of XYZ. Do you have anything to say as to why the sentence of this Court should not now be passed upon you?" The defense counsel will then make a plea in mitigation (also called submissions on penalty) in an attempt to mitigate the relative seriousness of the offense and heavily refer to and rely upon the defendant's previous good character and good works, if any. The right to make a plea in mitigation is absolute. If a judge or magistrate refuses to hear such a plea or does not properly consider it, the sentence can be overturned on appeal. United States In most of the United States, defendants are allowed the opportunity to allocute before a sentence is passed. Some jurisdictions hold that as an absolute right. In its absence, a sentence but not the conviction may be overturned, resulting in the need for a new sentencing hearing. In the federal system, Federal Rules of Criminal Procedure 32(i)(4) provides that the court must "address the defendant personally in order to permit the defendant to speak or present any information to mitigate the sentence." The Federal Public Defender recommends that defendants speak in terms of how a lenient sentence will be sufficient but not greater than necessary to comply with the statutory directives set forth in .

Affidavit An ( ; Medieval Latin for "he has declared under oath") is a written statement voluntarily made by an affiant or deponent under an oath or affirmation which is administered by a person who is authorized to do so by law. Such a statement is witnessed as to the authenticity of the affiant's signature by a taker of oaths, such as a notary public or commissioner of oaths. An affidavit is a type of verified statement or showing, or in other words, it contains a verification, which means that it is made under oath on penalty of perjury, and this serves as evidence for its veracity and is required in court proceedings. Definition An affidavit is typically defined as a written declaration or statement that is sworn or affirmed before a person who has authority to administer an oath. There is no general defined form for an affidavit, although for some proceedings an affidavit must satisfy legal or statutory requirements in order to be considered. An affidavit may include, a commencement which identifies the affiant; an attestation clause, usually a jurat, at the end certifying that the affiant made the statement under oath on the specified date; signatures of the affiant and person who administered the oath. In some cases, an introductory clause, called a preamble, is added attesting that the affiant personally appeared before the authenticating authority. An affidavit may also recite that the statement it records was made under penalty of perjury. An affidavit that is prepared for use within the context of litigation may also include a caption that identifies the venue and parties to the relevant judicial proceedings. Worldwide Australia On 2 March 2016, the High Court of Australia held that the ACT Uniform Evidence Legislation is neutral in the way sworn evidence and unsworn evidence is treated as being of equal weight. India In Indian law, although an affidavit may be taken as proof of the facts stated therein, the courts have no jurisdiction to admit evidence by way of affidavit. Affidavit is not treated as "evidence" within the meaning of Section 3 of the Evidence Act. However, it was held by the Supreme Court that an affidavit can be used as evidence only if the court so orders for sufficient reasons, namely, the right of the opposite party to have the deponent produced for cross-examination. Therefore, an affidavit cannot ordinarily be used as evidence in absence of a specific order of the court. Sri Lanka In Sri Lanka, under the Oaths Ordinance, with the exception of a court-martial, a person may submit an affidavit signed in the presence of a commissioner for oaths or a justice of the peace. Ireland Affidavits are made in a similar way as to England and Wales, although "make oath" is sometimes omitted. An affirmed affidavit may be substituted for an sworn affidavit in most cases for those opposed to swearing oaths. The person making the affidavit is known as the deponent and signs the affidavit.

The affidavit concludes in the standard format "sworn/affirmed (declared) before me, [name of commissioner for oaths/solicitor], a commissioner for oaths (solicitor), on the [date] at [location] in the county/city of [county/city], and I know the deponent", and it is signed and stamped by the commissioner for oaths. It is important that the Commissioner states his/her name clearly, sometimes documents are rejected when the name cannot be ascertained. In August 2020, a new method of filing affidavits came into force. Under Section 21 of the Civil Law and Criminal Law (Miscellaneous Provisions) Act 2020 witnesses are no longer required to swear before God or make an affirmation when filing an affidavit. Instead, witnesses will make a non-religious “statement of truth” and, if it is breached, will be liable for up to one year in prison if convicted summarily or, upon conviction on indictment, to a maximum fine of €250,000 or imprisonment for a term not exceeding 5 years, or both. This is designed to replace affidavits and statutory declarations in situations where the electronic means of lodgement or filing of documents with the Court provided for in Section 20 is utilised. As of January 2022, it has yet to be adopted widely, and it is expected it will not be used for some time by lay litigants who will still lodge papers in person. United States In American jurisprudence, under the rules for hearsay, admission of an unsupported affidavit as evidence is unusual (especially if the affiant is not available for cross-examination) with regard to material facts which may be dispositive of the matter at bar. Affidavits from persons who are dead or otherwise incapacitated, or who cannot be located or made to appear, may be accepted by the court, but usually only in the presence of corroborating evidence. An affidavit which reflected a better grasp of the facts close in time to the actual events may be used to refresh a witness's recollection. Materials used to refresh recollection are admissible as evidence. If the affiant is a party in the case, the affiant's opponent may be successful in having the affidavit admitted as evidence, as statements by a party-opponent are admissible through an exception to the hearsay rule. Affidavits are typically included in the response to interrogatories. Requests for admissions under Federal Rule of Civil Procedure 36, however, are not required to be sworn. When a person signs an affidavit, that person is eligible to take the stand at a trial or evidentiary hearing. One party may wish to summon the affiant to verify the contents of the affidavit, while the other party may want to cross-examine the affiant about the affidavit. Some types of motions will not be accepted by the court unless accompanied by an independent sworn statement or other evidence in support of the need for the motion.

In such a case, a court will accept an affidavit from the filing attorney in support of the motion, as certain assumptions are made, to wit: The affidavit in place of sworn testimony promotes judicial economy. The lawyer is an officer of the court and knows that a false swearing by them, if found out, could be grounds for severe penalty up to and including disbarment. The lawyer if called upon would be able to present independent and more detailed evidence to prove the facts set forth in his affidavit. The acceptance of an affidavit by one society does not confirm its acceptance as a legal document in other jurisdictions. Equally, the acceptance that a lawyer is an officer of the court (for swearing the affidavit) is not a given. This matter is addressed by the use of the apostille, a means of certifying the legalization of a document for international use under the terms of the 1961 Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents. Documents which have been notarized by a notary public, and certain other documents, and then certified with a conformant apostille, are accepted for legal use in all the nations that have signed the Hague Convention.

Aries (constellation) Aries is one of the constellations of the zodiac. It is located in the Northern celestial hemisphere between Pisces to the west and Taurus to the east. The name Aries is Latin for ram. Its old astronomical symbol is (♈︎). It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations. It is a mid-sized constellation, ranking 39th overall size, with an area of 441 square degrees (1.1% of the celestial sphere). Aries has represented a ram since late Babylonian times. Before that, the stars of Aries formed a farmhand. Different cultures have incorporated the stars of Aries into different constellations including twin inspectors in China and a porpoise in the Marshall Islands. Aries is a relatively dim constellation, possessing only four bright stars: Hamal (Alpha Arietis, second magnitude), Sheratan (Beta Arietis, third magnitude), Mesarthim (Gamma Arietis, fourth magnitude), and 41 Arietis (also fourth magnitude). The few deep-sky objects within the constellation are quite faint and include several pairs of interacting galaxies. Several meteor showers appear to radiate from Aries, including the Daytime Arietids and the Epsilon Arietids. History and mythology Aries is recognized as an official constellation now, albeit as a specific region of the sky, by the International Astronomical Union. It was originally defined in ancient texts as a specific pattern of stars, and has remained a constellation since ancient times; it now includes the ancient pattern as well as the surrounding stars. In the description of the Babylonian zodiac given in the clay tablets known as the MUL.APIN, the constellation, now known as Aries, was the final station along the ecliptic. The MUL.APIN was a comprehensive table of the risings and settings of stars, which likely served as an agricultural calendar. Modern-day Aries was known as , "The Agrarian Worker" or "The Hired Man". Although likely compiled in the 12th or 11th century BC, the MUL.APIN reflects a tradition which marks the Pleiades as the vernal equinox, which was the case with some precision at the beginning of the Middle Bronze Age. The earliest identifiable reference to Aries as a distinct constellation comes from the boundary stones that date from 1350 to 1000 BC. On several boundary stones, a zodiacal ram figure is distinct from the other characters present. The shift in identification from the constellation as the Agrarian Worker to the Ram likely occurred in later Babylonian tradition because of its growing association with Dumuzi the Shepherd. By the time the MUL.APIN was created—by 1000 BC—modern Aries was identified with both Dumuzi's ram and a hired laborer. The exact timing of this shift is difficult to determine due to the lack of images of Aries or other ram figures. In ancient Egyptian astronomy, Aries was associated with the god Amon-Ra, who was depicted as a man with a ram's head and represented fertility and creativity. Because it was the location of the vernal equinox, it was called the "Indicator of the Reborn Sun".

Because it was the location of the vernal equinox, it was called the "Indicator of the Reborn Sun".

During the times of the year when Aries was prominent, priests would process statues of Amon-Ra to temples, a practice that was modified by Persian astronomers centuries later. Aries acquired the title of "Lord of the Head" in Egypt, referring to its symbolic and mythological importance. Aries was not fully accepted as a constellation until classical times. In Hellenistic astrology, the constellation of Aries is associated with the golden ram of Greek mythology that rescued Phrixus and Helle on orders from Hermes, taking Phrixus to the land of Colchis. Phrixos and Helle were the son and daughter of King Athamas and his first wife Nephele. The king's second wife, Ino, was jealous and wished to kill his children. To accomplish this, she induced a famine in Boeotia, then falsified a message from the Oracle of Delphi that said Phrixos must be sacrificed to end the famine. Athamas was about to sacrifice his son atop Mount Laphystium when Aries, sent by Nephele, arrived. Helle fell off of Aries's back in flight and drowned in the Dardanelles, also called the Hellespont in her honor. Historically, Aries has been depicted as a crouched, wingless ram with its head turned towards Taurus. Ptolemy asserted in his Almagest that Hipparchus depicted Alpha Arietis as the ram's muzzle, though Ptolemy did not include it in his constellation figure. Instead, it was listed as an "unformed star", and denoted as "the star over the head". John Flamsteed, in his Atlas Coelestis, followed Ptolemy's description by mapping it above the figure's head. Flamsteed followed the general convention of maps by depicting Aries lying down. Astrologically, Aries has been associated with the head and its humors. It was strongly associated with Mars, both the planet and the god. It was considered to govern Western Europe and Syria, and to indicate a strong temper in a person. The First Point of Aries, the location of the vernal equinox, is named for the constellation. This is because the Sun crossed the celestial equator from south to north in Aries more than two millennia ago. Hipparchus defined it in 130 BC. as a point south of Gamma Arietis. Because of the precession of the equinoxes, the First Point of Aries has since moved into Pisces and will move into Aquarius by around 2600 AD. The Sun now appears in Aries from late April through mid May, though the constellation is still associated with the beginning of spring. Medieval Muslim astronomers depicted Aries in various ways. Astronomers like al-Sufi saw the constellation as a ram, modeled on the precedent of Ptolemy. However, some Islamic celestial globes depicted Aries as a nondescript four-legged animal with what may be antlers instead of horns. Some early Bedouin observers saw a ram elsewhere in the sky; this constellation featured the Pleiades as the ram's tail.

To accomplish this, she induced a famine in Boeotia, then falsified a message from the Oracle of Delphi that said Phrixos must be sacrificed to end the famine. Athamas was about to sacrifice his son atop Mount Laphystium when Aries, sent by Nephele, arrived. Helle fell off of Aries's back in flight and drowned in the Dardanelles, also called the Hellespont in her honor. Historically, Aries has been depicted as a crouched, wingless ram with its head turned towards Taurus. Ptolemy asserted in his Almagest that Hipparchus depicted Alpha Arietis as the ram's muzzle, though Ptolemy did not include it in his constellation figure. Instead, it was listed as an "unformed star", and denoted as "the star over the head". John Flamsteed, in his Atlas Coelestis, followed Ptolemy's description by mapping it above the figure's head. Flamsteed followed the general convention of maps by depicting Aries lying down. Astrologically, Aries has been associated with the head and its humors. It was strongly associated with Mars, both the planet and the god. It was considered to govern Western Europe and Syria, and to indicate a strong temper in a person. The First Point of Aries, the location of the vernal equinox, is named for the constellation. This is because the Sun crossed the celestial equator from south to north in Aries more than two millennia ago. Hipparchus defined it in 130 BC. as a point south of Gamma Arietis. Because of the precession of the equinoxes, the First Point of Aries has since moved into Pisces and will move into Aquarius by around 2600 AD. The Sun now appears in Aries from late April through mid May, though the constellation is still associated with the beginning of spring. Medieval Muslim astronomers depicted Aries in various ways. Astronomers like al-Sufi saw the constellation as a ram, modeled on the precedent of Ptolemy. However, some Islamic celestial globes depicted Aries as a nondescript four-legged animal with what may be antlers instead of horns. Some early Bedouin observers saw a ram elsewhere in the sky; this constellation featured the Pleiades as the ram's tail.

The generally accepted Arabic formation of Aries consisted of thirteen stars in a figure along with five "unformed" stars, four of which were over the animal's hindquarters and one of which was the disputed star over Aries's head. Al-Sufi's depiction differed from both other Arab astronomers' and Flamsteed's, in that his Aries was running and looking behind itself. The obsolete constellations of Aries (Apes/Vespa/Lilium/Musca (Borealis)) all centred on the same the northern stars. In 1612, Petrus Plancius introduced Apes, a constellation representing a bee. In 1624, the same stars were used by Jakob Bartsch as for Vespa, representing a wasp. In 1679, Augustin Royer used these stars for his constellation Lilium, representing the fleur-de-lis. None of these constellation became widely accepted. Johann Hevelius renamed the constellation "Musca" in 1690 in his Firmamentum Sobiescianum. To differentiate it from Musca, the southern fly, it was later renamed Musca Borealis but it did not gain acceptance and its stars were ultimately officially reabsorbed into Aries. The asterism involved was 33, 35, 39, and 41 Arietis. In 1922, the International Astronomical Union defined its recommended three-letter abbreviation, "Ari". The official boundaries of Aries were defined in 1930 by Eugène Delporte as a polygon of 12 segments. Its right ascension is between 1h 46.4m and 3h 29.4m and its declination is between 10.36° and 31.22° in the equatorial coordinate system. In non-Western astronomy In traditional Chinese astronomy, stars from Aries were used in several constellations. The brightest stars—Alpha, Beta, and Gamma Arietis—formed a constellation called Lou (婁), variously translated as "bond", "lasso", and "sickle", which was associated with the ritual sacrifice of cattle. This name was shared by the 16th lunar mansion, the location of the full moon closest to the autumnal equinox. This constellation has also been associated with harvest-time as it could represent a woman carrying a basket of food on her head. 35, 39, and 41 Arietis were part of a constellation called Wei (胃), which represented a fat abdomen and was the namesake of the 17th lunar mansion, which represented granaries. Delta and Zeta Arietis were a part of the constellation Tianyin (天陰), thought to represent the Emperor's hunting partner. Zuogeng (左更), a constellation depicting a marsh and pond inspector, was composed of Mu, Nu, Omicron, Pi, and Sigma Arietis. He was accompanied by Yeou-kang, a constellation depicting an official in charge of pasture distribution. In a similar system to the Chinese, the first lunar mansion in Hindu astronomy was called "Aswini", after the traditional names for Beta and Gamma Arietis, the Aswins. Because the Hindu new year began with the vernal equinox, the Rig Veda contains over 50 new-year's related hymns to the twins, making them some of the most prominent characters in the work. Aries itself was known as "Aja" and "Mesha". In Hebrew astronomy Aries was named "Taleh"; it signified either Simeon or Gad, and generally symbolizes the "Lamb of the World". The neighboring Syrians named the constellation "Amru", and the bordering Turks named it "Kuzi".

Half a world away, in the Marshall Islands, several stars from Aries were incorporated into a constellation depicting a porpoise, along with stars from Cassiopeia, Andromeda, and Triangulum. Alpha, Beta, and Gamma Arietis formed the head of the porpoise, while stars from Andromeda formed the body and the bright stars of Cassiopeia formed the tail. Other Polynesian peoples recognized Aries as a constellation. The Marquesas islanders called it Na-pai-ka; the Māori constellation Pipiri may correspond to modern Aries as well. In indigenous Peruvian astronomy, a constellation with most of the same stars as Aries existed. It was called the "Market Moon" and the "Kneeling Terrace", as a reminder for when to hold the annual harvest festival, Ayri Huay. Features Stars Aries has three prominent stars forming an asterism, designated Alpha, Beta, and Gamma Arietis by Johann Bayer. Alpha (Hamal) and Beta (Sheratan) are commonly used for navigation. There is also one other star above the fourth magnitude, 41 Arietis (Bharani). α Arietis, called Hamal, is the brightest star in Aries. Its traditional name is derived from the Arabic word for "lamb" or "head of the ram" (ras al-hamal), which references Aries's mythological background. With a spectral class of K2 and a luminosity class of III, it is an orange giant with an apparent visual magnitude of 2.00, which lies 66 light-years from Earth. Hamal has a luminosity of and its absolute magnitude is −0.1. β Arietis, also known as Sheratan, is a blue-white star with an apparent visual magnitude of 2.64. Its traditional name is derived from "sharatayn", the Arabic word for "the two signs", referring to both Beta and Gamma Arietis in their position as heralds of the vernal equinox. The two stars were known to the Bedouin as "qarna al-hamal", "horns of the ram". It is 59 light-years from Earth. It has a luminosity of and its absolute magnitude is 2.1. It is a spectroscopic binary star, one in which the companion star is only known through analysis of the spectra. The spectral class of the primary is A5. Hermann Carl Vogel determined that Sheratan was a spectroscopic binary in 1903; its orbit was determined by Hans Ludendorff in 1907. It has since been studied for its eccentric orbit. γ Arietis, with a common name of Mesarthim, is a binary star with two white-hued components, located in a rich field of magnitude 8–12 stars. Its traditional name has conflicting derivations. It may be derived from a corruption of "al-sharatan", the Arabic word meaning "pair" or a word for "fat ram". However, it may also come from the Sanskrit for "first star of Aries" or the Hebrew for "ministerial servants", both of which are unusual languages of origin for star names. Along with Beta Arietis, it was known to the Bedouin as "qarna al-hamal". The primary is of magnitude 4.59 and the secondary is of magnitude 4.68. The system is 164 light-years from Earth.

It was likely ejected from the Orion Nebula approximately five million years ago, possibly due to supernovae. Finally, Teegarden's Star is the closest star to Earth in Aries. It is a brown dwarf of magnitude 15.14 and spectral class M6.5V. With a proper motion of 5.1 arcseconds per year, it is the 24th closest star to Earth overall. Aries has its share of variable stars, including R and U Arietis, Mira-type variable stars, and T Arietis, a semi-regular variable star. R Arietis is a Mira variable star that ranges in magnitude from a minimum of 13.7 to a maximum of 7.4 with a period of 186.8 days. It is 4,080 light-years away. U Arietis is another Mira variable star that ranges in magnitude from a minimum of 15.2 to a maximum of 7.2 with a period of 371.1 days. T Arietis is a semiregular variable star that ranges in magnitude from a minimum of 11.3 to a maximum of 7.5 with a period of 317 days. It is 1,630 light-years away. One particularly interesting variable in Aries is SX Arietis, a rotating variable star considered to be the prototype of its class, helium variable stars. SX Arietis stars have very prominent emission lines of Helium I and Silicon III. They are normally main-sequence B0p—B9p stars, and their variations are not usually visible to the naked eye. Therefore, they are observed photometrically, usually having periods that fit in the course of one night. Similar to Alpha² Canum Venaticorum variables, SX Arietis stars have periodic changes in their light and magnetic field, which correspond to the periodic rotation; they differ from the Alpha² Canum Venaticorum variables in their higher temperature. There are between 39 and 49 SX Arietis variable stars currently known; ten are noted as being "uncertain" in the General Catalog of Variable Stars. Sky objects NGC 772 is a spiral galaxy with an integrated magnitude of 10.3, located southeast of β Arietis and 15 arcminutes west of 15 Arietis. It is a relatively bright galaxy and shows obvious nebulosity and ellipticity in an amateur telescope. It is 7.2 by 4.2 arcminutes, meaning that its surface brightness, magnitude 13.6, is significantly lower than its integrated magnitude. NGC 772 is a class SA(s)b galaxy, which means that it is an unbarred spiral galaxy without a ring that possesses a somewhat prominent bulge and spiral arms that are wound somewhat tightly. The main arm, on the northwest side of the galaxy, is home to many star forming regions; this is due to previous gravitational interactions with other galaxies. NGC 772 has a small companion galaxy, NGC 770, that is about 113,000 light-years away from the larger galaxy. The two galaxies together are also classified as Arp 78 in the Arp peculiar galaxy catalog. NGC 772 has a diameter of 240,000 light-years and the system is 114 million light-years from Earth.

Its absolute magnitude is −0.2. 53 Arietis is a runaway star of magnitude 6.09, 815 light-years away. Its spectral class is B2. It was likely ejected from the Orion Nebula approximately five million years ago, possibly due to supernovae. Finally, Teegarden's Star is the closest star to Earth in Aries. It is a brown dwarf of magnitude 15.14 and spectral class M6.5V. With a proper motion of 5.1 arcseconds per year, it is the 24th closest star to Earth overall. Aries has its share of variable stars, including R and U Arietis, Mira-type variable stars, and T Arietis, a semi-regular variable star. R Arietis is a Mira variable star that ranges in magnitude from a minimum of 13.7 to a maximum of 7.4 with a period of 186.8 days. It is 4,080 light-years away. U Arietis is another Mira variable star that ranges in magnitude from a minimum of 15.2 to a maximum of 7.2 with a period of 371.1 days. T Arietis is a semiregular variable star that ranges in magnitude from a minimum of 11.3 to a maximum of 7.5 with a period of 317 days. It is 1,630 light-years away. One particularly interesting variable in Aries is SX Arietis, a rotating variable star considered to be the prototype of its class, helium variable stars. SX Arietis stars have very prominent emission lines of Helium I and Silicon III. They are normally main-sequence B0p—B9p stars, and their variations are not usually visible to the naked eye. Therefore, they are observed photometrically, usually having periods that fit in the course of one night. Similar to Alpha² Canum Venaticorum variables, SX Arietis stars have periodic changes in their light and magnetic field, which correspond to the periodic rotation; they differ from the Alpha² Canum Venaticorum variables in their higher temperature. There are between 39 and 49 SX Arietis variable stars currently known; ten are noted as being "uncertain" in the General Catalog of Variable Stars.

Another spiral galaxy in Aries is NGC 673, a face-on class SAB(s)c galaxy. It is a weakly barred spiral galaxy with loosely wound arms. It has no ring and a faint bulge and is 2.5 by 1.9 arcminutes. It has two primary arms with fragments located farther from the core. 171,000 light-years in diameter, NGC 673 is 235 million light-years from Earth. NGC 678 and NGC 680 are a pair of galaxies in Aries that are only about 200,000 light-years apart. Part of the NGC 691 group of galaxies, both are at a distance of approximately 130 million light-years. NGC 678 is an edge-on spiral galaxy that is 4.5 by 0.8 arcminutes. NGC 680, an elliptical galaxy with an asymmetrical boundary, is the brighter of the two at magnitude 12.9; NGC 678 has a magnitude of 13.35. Both galaxies have bright cores, but NGC 678 is the larger galaxy at a diameter of 171,000 light-years; NGC 680 has a diameter of 72,000 light-years. NGC 678 is further distinguished by its prominent dust lane. NGC 691 itself is a spiral galaxy slightly inclined to our line of sight. It has multiple spiral arms and a bright core. Because it is so diffuse, it has a low surface brightness. It has a diameter of 126,000 light-years and is 124 million light-years away. NGC 877 is the brightest member of an 8-galaxy group that also includes NGC 870, NGC 871, and NGC 876, with a magnitude of 12.53. It is 2.4 by 1.8 arcminutes and is 178 million light-years away with a diameter of 124,000 light-years. Its companion is NGC 876, which is about 103,000 light-years from the core of NGC 877. They are interacting gravitationally, as they are connected by a faint stream of gas and dust. Arp 276 is a different pair of interacting galaxies in Aries, consisting of NGC 935 and IC 1801. NGC 821 is an E6 elliptical galaxy. It is unusual because it has hints of an early spiral structure, which is normally only found in lenticular and spiral galaxies. NGC 821 is 2.6 by 2.0 arcminutes and has a visual magnitude of 11.3. Its diameter is 61,000 light-years and it is 80 million light-years away. Another unusual galaxy in Aries is Segue 2, a dwarf and satellite galaxy of the Milky Way, recently discovered to be a potential relic of the epoch of reionization. Meteor showers Aries is home to several meteor showers. The Daytime Arietid meteor shower is one of the strongest meteor showers that occurs during the day, lasting from 22 May to 2 July. It is an annual shower associated with the Marsden group of comets that peaks on 7 June with a maximum zenithal hourly rate of 54 meteors. Its parent body may be the asteroid Icarus. The meteors are sometimes visible before dawn, because the radiant is 32 degrees away from the Sun.

The meteors are sometimes visible before dawn, because the radiant is 32 degrees away from the Sun.

They usually appear at a rate of 1–2 per hour as "earthgrazers", meteors that last several seconds and often begin at the horizon. Because most of the Daytime Arietids are not visible to the naked eye, they are observed in the radio spectrum. This is possible because of the ionized gas they leave in their wake. Other meteor showers radiate from Aries during the day; these include the Daytime Epsilon Arietids and the Northern and Southern Daytime May Arietids. The Jodrell Bank Observatory discovered the Daytime Arietids in 1947 when James Hey and G. S. Stewart adapted the World War II-era radar systems for meteor observations. The Delta Arietids are another meteor shower radiating from Aries. Peaking on 9 December with a low peak rate, the shower lasts from 8 December to 14 January, with the highest rates visible from 8 to 14 December. The average Delta Aquarid meteor is very slow, with an average velocity of per second. However, this shower sometimes produces bright fireballs. This meteor shower has northern and southern components, both of which are likely associated with 1990 HA, a near-Earth asteroid. The Autumn Arietids also radiate from Aries. The shower lasts from 7 September to 27 October and peaks on 9 October. Its peak rate is low. The Epsilon Arietids appear from 12 to 23 October. Other meteor showers radiating from Aries include the October Delta Arietids, Daytime Epsilon Arietids, Daytime May Arietids, Sigma Arietids, Nu Arietids, and Beta Arietids. The Sigma Arietids, a class IV meteor shower, are visible from 12 to 19 October, with a maximum zenithal hourly rate of less than two meteors per hour on 19 October. Planetary systems Aries contains several stars with extrasolar planets. HIP 14810, a G5 type star, is orbited by three giant planets (those more than ten times the mass of Earth). HD 12661, like HIP 14810, is a G-type main sequence star, slightly larger than the Sun, with two orbiting planets. One planet is 2.3 times the mass of Jupiter, and the other is 1.57 times the mass of Jupiter. HD 20367 is a G0 type star, approximately the size of the Sun, with one orbiting planet. The planet, discovered in 2002, has a mass 1.07 times that of Jupiter and orbits every 500 days. In 2019, scientists conducting the CARMENES survey at the Calar Alto Observatory announced evidence of two Earth-mass exoplanets orbiting the star within its habitable zone.

Aquarius (constellation) Aquarius is a constellation of the zodiac, between Capricornus and Pisces. Its name is Latin for "water-carrier" or "cup-carrier", and its old astronomical symbol is (♒︎), a representation of water. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river. At apparent magnitude 2.9, Beta Aquarii is the brightest star in the constellation. History and mythology Aquarius is identified as "The Great One" in the Babylonian star catalogues and represents the god Ea himself, who is commonly depicted holding an overflowing vase. The Babylonian star-figure appears on entitlement stones and cylinder seals from the second millennium. It contained the winter solstice in the Early Bronze Age. In Old Babylonian astronomy, Ea was the ruler of the southernmost quarter of the Sun's path, the "Way of Ea", corresponding to the period of 45 days on either side of winter solstice. Aquarius was also associated with the destructive floods that the Babylonians regularly experienced, and thus was negatively connoted. In Ancient Egypt astronomy, Aquarius was associated with the annual flood of the Nile; the banks were said to flood when Aquarius put his jar into the river, beginning spring. In the Greek tradition, the constellation came to be represented simply as a single vase from which a stream poured down to Piscis Austrinus. The name in the Hindu zodiac is likewise kumbha "water-pitcher". In Greek mythology, Aquarius is sometimes associated with Deucalion, the son of Prometheus who built a ship with his wife Pyrrha to survive an imminent flood. They sailed for nine days before washing ashore on Mount Parnassus. Aquarius is also sometimes identified with beautiful Ganymede, a youth in Greek mythology and the son of Trojan king Tros, who was taken to Mount Olympus by Zeus to act as cup-carrier to the gods. Neighboring Aquila represents the eagle, under Zeus' command, that snatched the young boy; some versions of the myth indicate that the eagle was in fact Zeus transformed. An alternative version of the tale recounts Ganymede's kidnapping by the goddess of the dawn, Eos, motivated by her affection for young men; Zeus then stole him from Eos and employed him as cup-bearer. Yet another figure associated with the water bearer is Cecrops I, a king of Athens who sacrificed water instead of wine to the gods. Depictions In the first century, Ptolemy's Almagest established the common Western depiction of Aquarius. His water jar, an asterism itself, consists of Gamma, Pi, Eta, and Zeta Aquarii; it pours water in a stream of more than 20 stars terminating with Fomalhaut, now assigned solely to Piscis Austrinus.

His water jar, an asterism itself, consists of Gamma, Pi, Eta, and Zeta Aquarii; it pours water in a stream of more than 20 stars terminating with Fomalhaut, now assigned solely to Piscis Austrinus.

The water bearer's head is represented by 5th magnitude 25 Aquarii while his left shoulder is Beta Aquarii; his right shoulder and forearm are represented by Alpha and Gamma Aquarii respectively. In Eastern astronomy In Chinese astronomy, the stream of water flowing from the Water Jar was depicted as the "Army of Yu-Lin" (Yu-lim-kiun or Yulinjun, Hanzi: 羽林君). The name "Yu-lin" means "feathers and forests", referring to the numerous light-footed soldiers from the northern reaches of the empire represented by these faint stars. The constellation's stars were the most numerous of any Chinese constellation, numbering 45, the majority of which were located in modern Aquarius. The celestial army was protected by the wall Leibizhen (垒壁阵), which counted Iota, Lambda, Phi, and Sigma Aquarii among its 12 stars. 88, 89, and 98 Aquarii represent Fou-youe, the axes used as weapons and for hostage executions. Also in Aquarius is Loui-pi-tchin, the ramparts that stretch from 29 and 27 Piscium and 33 and 30 Aquarii through Phi, Lambda, Sigma, and Iota Aquarii to Delta, Gamma, Kappa, and Epsilon Capricorni. Near the border with Cetus, the axe Fuyue was represented by three stars; its position is disputed and may have instead been located in Sculptor. Tienliecheng also has a disputed position; the 13-star castle replete with ramparts may have possessed Nu and Xi Aquarii but may instead have been located south in Piscis Austrinus. The Water Jar asterism was seen to the ancient Chinese as the tomb, Fenmu. Nearby, the emperors' mausoleum Xiuliang stood, demarcated by Kappa Aquarii and three other collinear stars. Ku ("crying") and Qi ("weeping"), each composed of two stars, were located in the same region. Three of the Chinese lunar mansions shared their name with constellations. Nu, also the name for the 10th lunar mansion, was a handmaiden represented by Epsilon, Mu, 3, and 4 Aquarii. The 11th lunar mansion shared its name with the constellation Xu ("emptiness"), formed by Beta Aquarii and Alpha Equulei; it represented a bleak place associated with death and funerals. Wei, the rooftop and 12th lunar mansion, was a V-shaped constellation formed by Alpha Aquarii, Theta Pegasi, and Epsilon Pegasi; it shared its name with two other Chinese constellations, in modern-day Scorpius and Aries. Features Stars Despite both its prominent position on the zodiac and its large size, Aquarius has no particularly bright stars, its four brightest stars being less than magnitude 2. However, recent research has shown that there are several stars lying within its borders that possess planetary systems. The two brightest stars, Alpha and Beta Aquarii, are luminous yellow supergiants, of spectral types G0Ib and G2Ib respectively, that were once hot blue-white B-class main sequence stars 5 to 9 times as massive as the Sun. The two are also moving through space perpendicular to the plane of the Milky Way. Just shading Alpha, Beta Aquarii is the brightest star in Aquarius with an apparent magnitude of 2.91. It also has the proper name of Sadalsuud.

The water bearer's head is represented by 5th magnitude 25 Aquarii while his left shoulder is Beta Aquarii; his right shoulder and forearm are represented by Alpha and Gamma Aquarii respectively. In Eastern astronomy In Chinese astronomy, the stream of water flowing from the Water Jar was depicted as the "Army of Yu-Lin" (Yu-lim-kiun or Yulinjun, Hanzi: 羽林君). The name "Yu-lin" means "feathers and forests", referring to the numerous light-footed soldiers from the northern reaches of the empire represented by these faint stars. The constellation's stars were the most numerous of any Chinese constellation, numbering 45, the majority of which were located in modern Aquarius. The celestial army was protected by the wall Leibizhen (垒壁阵), which counted Iota, Lambda, Phi, and Sigma Aquarii among its 12 stars. 88, 89, and 98 Aquarii represent Fou-youe, the axes used as weapons and for hostage executions. Also in Aquarius is Loui-pi-tchin, the ramparts that stretch from 29 and 27 Piscium and 33 and 30 Aquarii through Phi, Lambda, Sigma, and Iota Aquarii to Delta, Gamma, Kappa, and Epsilon Capricorni. Near the border with Cetus, the axe Fuyue was represented by three stars; its position is disputed and may have instead been located in Sculptor. Tienliecheng also has a disputed position; the 13-star castle replete with ramparts may have possessed Nu and Xi Aquarii but may instead have been located south in Piscis Austrinus. The Water Jar asterism was seen to the ancient Chinese as the tomb, Fenmu. Nearby, the emperors' mausoleum Xiuliang stood, demarcated by Kappa Aquarii and three other collinear stars. Ku ("crying") and Qi ("weeping"), each composed of two stars, were located in the same region. Three of the Chinese lunar mansions shared their name with constellations.

The planet's mass is 0.99 times that of Jupiter and its orbital period is 1,852 days. There are also less-prominent systems in Aquarius. WASP-6, a type G8 star of magnitude 12.4, is host to one exoplanet, WASP-6 b. The star is 307 parsecs from Earth and has a mass of 0.888 solar masses and a radius of 0.87 solar radii. WASP-6 b was discovered in 2008 by the transit method. It orbits its parent star every 3.36 days at a distance of 0.042 astronomical units (AU). It is 0.503 Jupiter masses but has a proportionally larger radius of 1.224 Jupiter radii. HD 206610, a K0 star located 194 parsecs from Earth, is host to one planet, HD 206610 b. The host star is larger than the Sun; more massive at 1.56 solar masses and larger at 6.1 solar radii. The planet was discovered by the radial velocity method in 2010 and has a mass of 2.2 Jupiter masses. It orbits every 610 days at a distance of 1.68 AU. Much closer to its sun is WASP-47 b, which orbits every 4.15 days only 0.052 AU from its sun, yellow dwarf (G9V) WASP-47. WASP-47 is close in size to the Sun, having a radius of 1.15 solar radii and a mass even closer at 1.08 solar masses. WASP-47 b was discovered in 2011 by the transit method, like WASP-6 b. It is slightly larger than Jupiter with a mass of 1.14 Jupiter masses and a radius of 1.15 Jupiter masses. There are several more single-planet systems in Aquarius. HD 210277, a magnitude 6.63 yellow star located 21.29 parsecs from Earth, is host to one known planet: HD 210277 b. The 1.23 Jupiter mass planet orbits at nearly the same distance as Earth orbits the Sun1.1 AU, though its orbital period is significantly longer at around 442 days. HD 210277 b was discovered earlier than most of the other planets in Aquarius, detected by the radial velocity method in 1998. The star it orbits resembles the Sun beyond their similar spectral class; it has a radius of 1.1 solar radii and a mass of 1.09 solar masses. HD 212771 b, a larger planet at 2.3 Jupiter masses, orbits host star HD 212771 at a distance of 1.22 AU. The star itself, barely below the threshold of naked-eye visibility at magnitude 7.6, is a G8IV (yellow subgiant) star located 131 parsecs from Earth. Though it has a similar mass to the Sun1.15 solar massesit is significantly less dense with its radius of 5 solar radii. Its lone planet was discovered in 2010 by the radial velocity method, like several other exoplanets in the constellation. As of 2013, there were only two known multiple-planet systems within the bounds of Aquarius: the Gliese 876 and HD 215152 systems. The former is quite prominent; the latter has only two planets and has a host star farther away at 21.5 parsecs.

The HD 215152 system consists of the planets HD 215152 b and HD 215152 c orbiting their K0-type, magnitude 8.13 sun. Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star. HD 215152 c is the larger at 0.0097 Jupiter masses (still significantly larger than the Earth, which weighs in at 0.00315 Jupiter masses); its smaller sibling is barely smaller at 0.0087 Jupiter masses. The error in the mass measurements (0.0032 and respectively) is large enough to make this discrepancy statistically insignificant. HD 215152 c also orbits further from the star than HD 215152 b, 0.0852 AU compared to 0.0652. On 23 February 2017, NASA announced that ultracool dwarf star TRAPPIST-1 in Aquarius has seven Earth-like rocky planets. Of these, three are in the system's habitable zone, and may contain water. The discovery of the TRAPPIST-1 system is seen by astronomers as a significant step toward finding life beyond Earth. Deep sky objects Because of its position away from the galactic plane, the majority of deep-sky objects in Aquarius are galaxies, globular clusters, and planetary nebulae. Aquarius contains three deep sky objects that are in the Messier catalog: the globular clusters Messier 2, Messier 72, and the asterism Messier 73. While M73 was originally catalogued as a sparsely populated open cluster, modern analysis indicates the 6 main stars are not close enough together to fit this definition, reclassifying M73 as an asterism. Two well-known planetary nebulae are also located in Aquarius: the Saturn Nebula (NGC 7009), to the southeast of μ Aquarii; and the famous Helix Nebula (NGC 7293), southwest of δ Aquarii. M2, also catalogued as NGC 7089, is a rich globular cluster located approximately 37,000 light-years from Earth. At magnitude 6.5, it is viewable in small-aperture instruments, but a 100 mm aperture telescope is needed to resolve any stars. M72, also catalogued as NGC 6981, is a small 9th magnitude globular cluster located approximately 56,000 light-years from Earth. M73, also catalogued as NGC 6994, is an open cluster with highly disputed status. Aquarius is also home to several planetary nebulae. NGC 7009, also known as the Saturn Nebula, is an 8th magnitude planetary nebula located 3,000 light-years from Earth. It was given its moniker by the 19th century astronomer Lord Rosse for its resemblance to the planet Saturn in a telescope; it has faint protrusions on either side that resemble Saturn's rings. It appears blue-green in a telescope and has a central star of magnitude 11.3. Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth. However, because it is so large, it is only viewable as a very faint object, though it has a fairly high integrated magnitude of 6.0.

The HD 215152 system consists of the planets HD 215152 b and HD 215152 c orbiting their K0-type, magnitude 8.13 sun. Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star.

NGC 7009, also known as the Saturn Nebula, is an 8th magnitude planetary nebula located 3,000 light-years from Earth. It was given its moniker by the 19th century astronomer Lord Rosse for its resemblance to the planet Saturn in a telescope; it has faint protrusions on either side that resemble Saturn's rings. It appears blue-green in a telescope and has a central star of magnitude 11.3. Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth. However, because it is so large, it is only viewable as a very faint object, though it has a fairly high integrated magnitude of 6.0.

The HD 215152 system consists of the planets HD 215152 b and HD 215152 c orbiting their K0-type, magnitude 8.13 sun. Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star. HD 215152 c is the larger at 0.0097 Jupiter masses (still significantly larger than the Earth, which weighs in at 0.00315 Jupiter masses); its smaller sibling is barely smaller at 0.0087 Jupiter masses. The error in the mass measurements (0.0032 and respectively) is large enough to make this discrepancy statistically insignificant. HD 215152 c also orbits further from the star than HD 215152 b, 0.0852 AU compared to 0.0652. On 23 February 2017, NASA announced that ultracool dwarf star TRAPPIST-1 in Aquarius has seven Earth-like rocky planets. Of these, three are in the system's habitable zone, and may contain water. The discovery of the TRAPPIST-1 system is seen by astronomers as a significant step toward finding life beyond Earth. Deep sky objects Because of its position away from the galactic plane, the majority of deep-sky objects in Aquarius are galaxies, globular clusters, and planetary nebulae. Aquarius contains three deep sky objects that are in the Messier catalog: the globular clusters Messier 2, Messier 72, and the asterism Messier 73. While M73 was originally catalogued as a sparsely populated open cluster, modern analysis indicates the 6 main stars are not close enough together to fit this definition, reclassifying M73 as an asterism. Two well-known planetary nebulae are also located in Aquarius: the Saturn Nebula (NGC 7009), to the southeast of μ Aquarii; and the famous Helix Nebula (NGC 7293), southwest of δ Aquarii. M2, also catalogued as NGC 7089, is a rich globular cluster located approximately 37,000 light-years from Earth. At magnitude 6.5, it is viewable in small-aperture instruments, but a 100 mm aperture telescope is needed to resolve any stars. M72, also catalogued as NGC 6981, is a small 9th magnitude globular cluster located approximately 56,000 light-years from Earth. M73, also catalogued as NGC 6994, is an open cluster with highly disputed status. Aquarius is also home to several planetary nebulae.

One of the visible galaxies in Aquarius is NGC 7727, of particular interest for amateur astronomers who wish to discover or observe supernovae. A spiral galaxy (type S), it has an integrated magnitude of 10.7 and is 3 by 3 arcseconds. NGC 7252 is a tangle of stars resulting from the collision of two large galaxies and is known as the Atoms-for-Peace galaxy because of its resemblance to a cartoon atom. Meteor showers There are three major meteor showers with radiants in Aquarius: the Eta Aquariids, the Delta Aquariids, and the Iota Aquariids. The Eta Aquariids are the strongest meteor shower radiating from Aquarius. It peaks between 5 and 6 May with a rate of approximately 35 meteors per hour. Originally discovered by Chinese astronomers in 401, Eta Aquariids can be seen coming from the Water Jar beginning on 21 April and as late as 12 May. The parent body of the shower is Halley's Comet, a periodic comet. Fireballs are common shortly after the peak, approximately between 9 May and 11 May. The normal meteors appear to have yellow trails. The Delta Aquariids is a double radiant meteor shower that peaks first on 29 July and second on 6 August. The first radiant is located in the south of the constellation, while the second radiant is located in the northern circlet of Pisces asterism. The southern radiant's peak rate is about 20 meteors per hour, while the northern radiant's peak rate is about 10 meteors per hour. The Iota Aquariids is a fairly weak meteor shower that peaks on 6 August, with a rate of approximately 8 meteors per hour. Astrology , the Sun appears in the constellation Aquarius from 16 February to 12 March. In tropical astrology, the Sun is considered to be in the sign Aquarius from 20 January to 19 February, and in sidereal astrology, from 15 February to 14 March. Aquarius is also associated with the Age of Aquarius, a concept popular in 1960s counterculture. Despite this prominence, the Age of Aquarius will not dawn until the year 2597, as an astrological age does not begin until the Sun is in a particular constellation on the vernal equinox.

Anime is hand-drawn and computer animation originating from Japan. In Japan and in Japanese, (a term derived from the English word animation) describes all animated works, regardless of style or origin. However, outside of Japan and in English, anime is colloquial for Japanese animation and refers specifically to animation produced in Japan. Animation produced outside of Japan with similar style to Japanese animation is referred to as anime-influenced animation. The earliest commercial Japanese animations date to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, directly to home media, and over the Internet. In addition to original works, anime are often adaptations of Japanese comics (manga), light novels, or video games. It is classified into numerous genres targeting various broad and niche audiences. Anime is a diverse medium with distinctive production methods that have adapted in response to emergent technologies. It combines graphic art, characterization, cinematography, and other forms of imaginative and individualistic techniques. Compared to Western animation, anime production generally focuses less on movement, and more on the detail of settings and use of "camera effects", such as panning, zooming, and angle shots. Diverse art styles are used, and character proportions and features can be quite varied, with a common characteristic feature being large and emotive eyes. The anime industry consists of over 430 production companies, including major studios like Studio Ghibli, Sunrise, Ufotable, CoMix Wave Films and Toei Animation. Since the 1980s, the medium has also seen international success with the rise of foreign dubbed, subtitled programming and its increasing distribution through streaming services. As of 2016, Japanese anime accounted for 60% of the world's animated television shows. In 2019, the annual overseas exports of Japanese animation exceeded $10 billion for the first time in history. Etymology As a type of animation, anime is an art form that comprises many genres found in other mediums; it is sometimes mistakenly classified as a genre itself. In Japanese, the term anime is used to refer to all animated works, regardless of style or origin. English-language dictionaries typically define anime () as "a style of Japanese animation" or as "a style of animation originating in Japan". Other definitions are based on origin, making production in Japan a requisite for a work to be considered "anime". The etymology of the term anime is disputed. The English word "animation" is written in Japanese katakana as () and as (, ) in its shortened form. Some sources claim that the term is derived from the French term for animation ("cartoon", literally 'animated design'), but others believe this to be a myth derived from the popularity of anime in France in the late 1970s and 1980s. In English, anime—when used as a common noun—normally functions as a mass noun. (For example: "Do you watch anime?" or "How much anime have you collected?")

As with a few other Japanese words, such as saké and Pokémon, English texts sometimes spell anime as animé (as in French), with an acute accent over the final e, to cue the reader to pronounce the letter, not to leave it silent as English orthography may suggest. Prior to the widespread use of anime, the term Japanimation was prevalent throughout the 1970s and 1980s. In the mid-1980s, the term anime began to supplant Japanimation; in general, the latter term now only appears in period works where it is used to distinguish and identify Japanese animation. History Precursors Emakimono and kagee are considered precursors of Japanese animation. Emakimono was common in the eleventh century. Traveling storytellers narrated legends and anecdotes while the emakimono was unrolled from the right to left with chronological order, as a moving panorama. Kagee was popular during the Edo period and originated from the shadows play of China. Magic lanterns from the Netherlands were also popular in the eighteenth century. The paper play called Kamishibai surged in the twelfth century and remained popular in the street theater until the 1930s. Puppets of the bunraku theater and ukiyo-e prints are considered ancestors of characters of most Japanese animations. Finally, mangas were a heavy inspiration for Japanese anime. Cartoonists Kitzawa Rakuten and Okamoto Ippei used film elements in their strips. Pioneers Animation in Japan began in the early 20th century, when filmmakers started to experiment with techniques pioneered in France, Germany, the United States, and Russia. A claim for the earliest Japanese animation is Katsudō Shashin (), a private work by an unknown creator. In 1917, the first professional and publicly displayed works began to appear; animators such as Ōten Shimokawa, Seitarō Kitayama, and Jun'ichi Kōuchi (considered the "fathers of anime") produced numerous films, the oldest surviving of which is Kōuchi's Namakura Gatana. Many early works were lost with the destruction of Shimokawa's warehouse in the 1923 Great Kantō earthquake. By the mid-1930s, animation was well-established in Japan as an alternative format to the live-action industry. It suffered competition from foreign producers, such as Disney, and many animators, including Noburō Ōfuji and Yasuji Murata, continued to work with cheaper cutout animation rather than cel animation. Other creators, including Kenzō Masaoka and Mitsuyo Seo, nevertheless made great strides in technique, benefiting from the patronage of the government, which employed animators to produce educational shorts and propaganda. In 1940, the government dissolved several artists' organizations to form the The first talkie anime was Chikara to Onna no Yo no Naka (1933), a short film produced by Masaoka. The first feature-length anime film was Momotaro: Sacred Sailors (1945), produced by Seo with a sponsorship from the Imperial Japanese Navy. The 1950s saw a proliferation of short, animated advertisements created for television. Modern era In the 1960s, manga artist and animator Osamu Tezuka adapted and simplified Disney animation techniques to reduce costs and limit frame counts in his productions.

The 1950s saw a proliferation of short, animated advertisements created for television. Modern era In the 1960s, manga artist and animator Osamu Tezuka adapted and simplified Disney animation techniques to reduce costs and limit frame counts in his productions.

Originally intended as temporary measures to allow him to produce material on a tight schedule with an inexperienced staff, many of his limited animation practices came to define the medium's style. Three Tales (1960) was the first anime film broadcast on television; the first anime television series was Instant History (1961–64). An early and influential success was Astro Boy (1963–66), a television series directed by Tezuka based on his manga of the same name. Many animators at Tezuka's Mushi Production later established major anime studios (including Madhouse, Sunrise, and Pierrot). The 1970s saw growth in the popularity of manga, many of which were later animated. Tezuka's work—and that of other pioneers in the field—inspired characteristics and genres that remain fundamental elements of anime today. The giant robot genre (also known as "mecha"), for instance, took shape under Tezuka, developed into the super robot genre under Go Nagai and others, and was revolutionized at the end of the decade by Yoshiyuki Tomino, who developed the real robot genre. Robot anime series such as Gundam and Super Dimension Fortress Macross became instant classics in the 1980s, and the genre remained one of the most popular in the following decades. The bubble economy of the 1980s spurred a new era of high-budget and experimental anime films, including Nausicaä of the Valley of the Wind (1984), Royal Space Force: The Wings of Honnêamise (1987), and Akira (1988). Neon Genesis Evangelion (1995), a television series produced by Gainax and directed by Hideaki Anno, began another era of experimental anime titles, such as Ghost in the Shell (1995) and Cowboy Bebop (1998). In the 1990s, anime also began attracting greater interest in Western countries; major international successes include Sailor Moon and Dragon Ball Z, both of which were dubbed into more than a dozen languages worldwide. In 2003, Spirited Away, a Studio Ghibli feature film directed by Hayao Miyazaki, won the Academy Award for Best Animated Feature at the 75th Academy Awards. It later became the highest-grossing anime film, earning more than $355 million. Since the 2000s, an increased number of anime works have been adaptations of light novels and visual novels; successful examples include The Melancholy of Haruhi Suzumiya and Fate/stay night (both 2006). Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train became the highest-grossing Japanese film and one of the world's highest-grossing films of 2020. It also became the fastest grossing film in Japanese cinema, because in 10 days it made 10 billion yen ($95.3m; £72m). It beat the previous record of Spirited Away which took 25 days. Attributes Anime differs greatly from other forms of animation by its diverse art styles, methods of animation, its production, and its process. Visually, anime works exhibit a wide variety of art styles, differing between creators, artists, and studios. While no single art style predominates anime as a whole, they do share some similar attributes in terms of animation technique and character design.

The giant robot genre (also known as "mecha"), for instance, took shape under Tezuka, developed into the super robot genre under Go Nagai and others, and was revolutionized at the end of the decade by Yoshiyuki Tomino, who developed the real robot genre. Robot anime series such as Gundam and Super Dimension Fortress Macross became instant classics in the 1980s, and the genre remained one of the most popular in the following decades. The bubble economy of the 1980s spurred a new era of high-budget and experimental anime films, including Nausicaä of the Valley of the Wind (1984), Royal Space Force: The Wings of Honnêamise (1987), and Akira (1988). Neon Genesis Evangelion (1995), a television series produced by Gainax and directed by Hideaki Anno, began another era of experimental anime titles, such as Ghost in the Shell (1995) and Cowboy Bebop (1998). In the 1990s, anime also began attracting greater interest in Western countries; major international successes include Sailor Moon and Dragon Ball Z, both of which were dubbed into more than a dozen languages worldwide. In 2003, Spirited Away, a Studio Ghibli feature film directed by Hayao Miyazaki, won the Academy Award for Best Animated Feature at the 75th Academy Awards. It later became the highest-grossing anime film, earning more than $355 million. Since the 2000s, an increased number of anime works have been adaptations of light novels and visual novels; successful examples include The Melancholy of Haruhi Suzumiya and Fate/stay night (both 2006). Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train became the highest-grossing Japanese film and one of the world's highest-grossing films of 2020. It also became the fastest grossing film in Japanese cinema, because in 10 days it made 10 billion yen ($95.3m; £72m). It beat the previous record of Spirited Away which took 25 days. Attributes Anime differs greatly from other forms of animation by its diverse art styles, methods of animation, its production, and its process. Visually, anime works exhibit a wide variety of art styles, differing between creators, artists, and studios. While no single art style predominates anime as a whole, they do share some similar attributes in terms of animation technique and character design.

Technique Modern anime follows a typical animation production process, involving storyboarding, voice acting, character design, and cel production. Since the 1990s, animators have increasingly used computer animation to improve the efficiency of the production process. Early anime works were experimental, and consisted of images drawn on blackboards, stop motion animation of paper cutouts, and silhouette animation. Cel animation grew in popularity until it came to dominate the medium. In the 21st century, the use of other animation techniques is mostly limited to independent short films, including the stop motion puppet animation work produced by Tadahito Mochinaga, Kihachirō Kawamoto and Tomoyasu Murata. Computers were integrated into the animation process in the 1990s, with works such as Ghost in the Shell and Princess Mononoke mixing cel animation with computer-generated images. Fuji Film, a major cel production company, announced it would stop cel production, producing an industry panic to procure cel imports and hastening the switch to digital processes. Prior to the digital era, anime was produced with traditional animation methods using a pose to pose approach. The majority of mainstream anime uses fewer expressive key frames and more in-between animation. Japanese animation studios were pioneers of many limited animation techniques, and have given anime a distinct set of conventions. Unlike Disney animation, where the emphasis is on the movement, anime emphasizes the art quality and let limited animation techniques make up for the lack of time spent on movement. Such techniques are often used not only to meet deadlines but also as artistic devices. Anime scenes place emphasis on achieving three-dimensional views, and backgrounds are instrumental in creating the atmosphere of the work. The backgrounds are not always invented and are occasionally based on real locations, as exemplified in Howl's Moving Castle and The Melancholy of Haruhi Suzumiya. Oppliger stated that anime is one of the rare mediums where putting together an all-star cast usually comes out looking "tremendously impressive". The cinematic effects of anime differentiates itself from the stage plays found in American animation. Anime is cinematically shot as if by camera, including panning, zooming, distance and angle shots to more complex dynamic shots that would be difficult to produce in reality. In anime, the animation is produced before the voice acting, contrary to American animation which does the voice acting first. Characters The body proportions of human anime characters tend to accurately reflect the proportions of the human body in reality. The height of the head is considered by the artist as the base unit of proportion. Head heights can vary, but most anime characters are about seven to eight heads tall. Anime artists occasionally make deliberate modifications to body proportions to produce super deformed characters that feature a disproportionately small body compared to the head; many super deformed characters are two to four heads tall. Some anime works like Crayon Shin-chan completely disregard these proportions, in such a way that they resemble caricatured Western cartoons. A common anime character design convention is exaggerated eye size.

The animation of characters with large eyes in anime can be traced back to Osamu Tezuka, who was deeply influenced by such early animation characters as Betty Boop, who was drawn with disproportionately large eyes. Tezuka is a central figure in anime and manga history, whose iconic art style and character designs allowed for the entire range of human emotions to be depicted solely through the eyes. The artist adds variable color shading to the eyes and particularly to the cornea to give them greater depth. Generally, a mixture of a light shade, the tone color, and a dark shade is used. Cultural anthropologist Matt Thorn argues that Japanese animators and audiences do not perceive such stylized eyes as inherently more or less foreign. However, not all anime characters have large eyes. For example, the works of Hayao Miyazaki are known for having realistically proportioned eyes, as well as realistic hair colors on their characters. Hair in anime is often unnaturally lively and colorful or uniquely styled. The movement of hair in anime is exaggerated and "hair action" is used to emphasize the action and emotions of characters for added visual effect. Poitras traces hairstyle color to cover illustrations on manga, where eye-catching artwork and colorful tones are attractive for children's manga. Despite being produced for a domestic market, anime features characters whose race or nationality is not always defined, and this is often a deliberate decision, such as in the Pokémon animated series. Anime and manga artists often draw from a common canon of iconic facial expression illustrations to denote particular moods and thoughts. These techniques are often different in form than their counterparts in Western animation, and they include a fixed iconography that is used as shorthand for certain emotions and moods. For example, a male character may develop a nosebleed when aroused. A variety of visual symbols are employed, including sweat drops to depict nervousness, visible blushing for embarrassment, or glowing eyes for an intense glare. Another recurring sight gag is the use of chibi (deformed, simplified character designs) figures to comedically punctuate emotions like confusion or embarrassment. Music The opening and credits sequences of most anime television series are accompanied by J-pop or J-rock songs, often by reputed bands—as written with the series in mind—but are also aimed at the general music market, therefore they often allude only vaguely or not at all, to the thematic settings or plot of the series. Also, they are often used as incidental music ("insert songs") in an episode, in order to highlight particularly important scenes. Genres Anime are often classified by target demographic, including , , and a diverse range of genres targeting an adult audience. Shoujo and shounen anime sometimes contain elements popular with children of both sexes in an attempt to gain crossover appeal. Adult anime may feature a slower pace or greater plot complexity that younger audiences may typically find unappealing, as well as adult themes and situations.

A subset of adult anime works featuring pornographic elements are labeled "R18" in Japan, and are internationally known as hentai (originating from ). By contrast, some anime subgenres incorporate ecchi, sexual themes or undertones without depictions of sexual intercourse, as typified in the comedic or harem genres; due to its popularity among adolescent and adult anime enthusiasts, the inclusion of such elements is considered a form of fan service. Some genres explore homosexual romances, such as yaoi (male homosexuality) and yuri (female homosexuality). While often used in a pornographic context, the terms yaoi and yuri can also be used broadly in a wider context to describe or focus on the themes or the development of the relationships themselves. Anime's genre classification differs from other types of animation and does not lend itself to simple classification. Gilles Poitras compared the labeling Gundam 0080 and its complex depiction of war as a "giant robot" anime akin to simply labeling War and Peace a "war novel". Science fiction is a major anime genre and includes important historical works like Tezuka's Astro Boy and Yokoyama's Tetsujin 28-go. A major subgenre of science fiction is mecha, with the Gundam metaseries being iconic. The diverse fantasy genre includes works based on Asian and Western traditions and folklore; examples include the Japanese feudal fairytale InuYasha, and the depiction of Scandinavian goddesses who move to Japan to maintain a computer called Yggdrasil in Ah! My Goddess. Genre crossing in anime is also prevalent, such as the blend of fantasy and comedy in Dragon Half, and the incorporation of slapstick humor in the crime anime film Castle of Cagliostro. Other subgenres found in anime include magical girl, harem, sports, martial arts, literary adaptations, medievalism, and war. Formats Early anime works were made for theatrical viewing, and required played musical components before sound and vocal components were added to the production. In 1958, Nippon Television aired Mogura no Abanchūru ("Mole's Adventure"), both the first televised and first color anime to debut. It was not until the 1960s when the first televised series were broadcast and it has remained a popular medium since. Works released in a direct to video format are called "original video animation" (OVA) or "original animation video" (OAV); and are typically not released theatrically or televised prior to home media release. The emergence of the Internet has led some animators to distribute works online in a format called "original net anime" (ONA). The home distribution of anime releases were popularized in the 1980s with the VHS and LaserDisc formats. The VHS NTSC video format used in both Japan and the United States is credited as aiding the rising popularity of anime in the 1990s. The LaserDisc and VHS formats were transcended by the DVD format which offered the unique advantages; including multiple subtitling and dubbing tracks on the same disc.

The DVD format also has its drawbacks in its usage of region coding; adopted by the industry to solve licensing, piracy and export problems and restricted region indicated on the DVD player. The Video CD (VCD) format was popular in Hong Kong and Taiwan, but became only a minor format in the United States that was closely associated with bootleg copies. A key characteristic of many anime television shows is serialization, where a continuous story arc stretches over multiple episodes or seasons. Traditional American television had an episodic format, with each episode typically consisting of a self-contained story. In contrast, anime shows such as Dragon Ball Z had a serialization format, where continuous story arcs stretch over multiple episodes or seasons, which distinguished them from traditional American television shows; serialization has since also become a common characteristic of American streaming television shows during the "Peak TV" era. Industry The animation industry consists of more than 430 production companies with some of the major studios including Toei Animation, Gainax, Madhouse, Gonzo, Sunrise, Bones, TMS Entertainment, Nippon Animation, P.A.Works, Studio Pierrot and Studio Ghibli. Many of the studios are organized into a trade association, The Association of Japanese Animations. There is also a labor union for workers in the industry, the Japanese Animation Creators Association. Studios will often work together to produce more complex and costly projects, as done with Studio Ghibli's Spirited Away. An anime episode can cost between US$100,000 and US$300,000 to produce. In 2001, animation accounted for 7% of the Japanese film market, above the 4.6% market share for live-action works. The popularity and success of anime is seen through the profitability of the DVD market, contributing nearly 70% of total sales. According to a 2016 article on Nikkei Asian Review, Japanese television stations have bought over worth of anime from production companies "over the past few years", compared with under from overseas. There has been a rise in sales of shows to television stations in Japan, caused by late night anime with adults as the target demographic. This type of anime is less popular outside Japan, being considered "more of a niche product". Spirited Away (2001) is the all-time highest-grossing film in Japan. It was also the highest-grossing anime film worldwide until it was overtaken by Makoto Shinkai's 2016 film Your Name. Anime films represent a large part of the highest-grossing Japanese films yearly in Japan, with 6 out of the top 10 in 2014, in 2015 and also in 2016. Anime has to be licensed by companies in other countries in order to be legally released. While anime has been licensed by its Japanese owners for use outside Japan since at least the 1960s, the practice became well-established in the United States in the late 1970s to early 1980s, when such TV series as Gatchaman and Captain Harlock were licensed from their Japanese parent companies for distribution in the US market.

According to a 2016 article on Nikkei Asian Review, Japanese television stations have bought over worth of anime from production companies "over the past few years", compared with under from overseas. There has been a rise in sales of shows to television stations in Japan, caused by late night anime with adults as the target demographic. This type of anime is less popular outside Japan, being considered "more of a niche product". Spirited Away (2001) is the all-time highest-grossing film in Japan. It was also the highest-grossing anime film worldwide until it was overtaken by Makoto Shinkai's 2016 film Your Name. Anime films represent a large part of the highest-grossing Japanese films yearly in Japan, with 6 out of the top 10 in 2014, in 2015 and also in 2016. Anime has to be licensed by companies in other countries in order to be legally released. While anime has been licensed by its Japanese owners for use outside Japan since at least the 1960s, the practice became well-established in the United States in the late 1970s to early 1980s, when such TV series as Gatchaman and Captain Harlock were licensed from their Japanese parent companies for distribution in the US market.

The trend towards American distribution of anime continued into the 1980s with the licensing of titles such as Voltron and the 'creation' of new series such as Robotech through use of source material from several original series. In the early 1990s, several companies began to experiment with the licensing of less children-oriented material. Some, such as A.D. Vision, and Central Park Media and its imprints, achieved fairly substantial commercial success and went on to become major players in the now very lucrative American anime market. Others, such as AnimEigo, achieved limited success. Many companies created directly by Japanese parent companies did not do as well, most releasing only one or two titles before completing their American operations. Licenses are expensive, often hundreds of thousands of dollars for one series and tens of thousands for one movie. The prices vary widely; for example, Jinki: Extend cost only $91,000 to license while Kurau Phantom Memory cost $960,000. Simulcast Internet streaming rights can be cheaper, with prices around $1,000-$2,000 an episode, but can also be more expensive, with some series costing more than per episode. The anime market for the United States was worth approximately $2.74 billion in 2009, today in 2022 the anime market for the United States is worth approximately $25 billion. Dubbed animation began airing in the United States in 2000 on networks like The WB and Cartoon Network's Adult Swim. In 2005, this resulted in five of the top ten anime titles having previously aired on Cartoon Network. As a part of localization, some editing of cultural references may occur to better follow the references of the non-Japanese culture. The cost of English localization averages US$10,000 per episode. The industry has been subject to both praise and condemnation for fansubs, the addition of unlicensed and unauthorized subtitled translations of anime series or films. Fansubs, which were originally distributed on VHS bootlegged cassettes in the 1980s, have been freely available and disseminated online since the 1990s. Since this practice raises concerns for copyright and piracy issues, fansubbers tend to adhere to an unwritten moral code to destroy or no longer distribute an anime once an official translated or subtitled version becomes licensed. They also try to encourage viewers to buy an official copy of the release once it comes out in English, although fansubs typically continue to circulate through file-sharing networks. Even so, the laid back regulations of the Japanese animation industry tend to overlook these issues, allowing it to grow underground and thus increasing the popularity until there is a demand for official high-quality releases for animation companies. This has led to an increase in global popularity with Japanese animations, reaching $40 million in sales in 2004. Since the 2010s anime has become a global multibillion industry setting a sales record in 2017 of ¥2.15 trillion ($19.8 billion), driven largely by demand from overseas audiences.

In 2019, Japan's anime industry was valued at $24 billion a year with 48% of that revenue coming from overseas (which is now its largest industry sector). By 2025 the anime industry is expected to reach a value of $30 billion with over 60% of that revenue to come from overseas. Markets Japan External Trade Organization (JETRO) valued the domestic anime market in Japan at (), including from licensed products, in 2005. JETRO reported sales of overseas anime exports in 2004 to be (). JETRO valued the anime market in the United States at (), including in home video sales and over from licensed products, in 2005. JETRO projected in 2005 that the worldwide anime market, including sales of licensed products, would grow to (). The anime market in China was valued at in 2017, and is projected to reach by 2020. By 2030 the global anime market is expected to reach a value of $48.3 Billion with the largest contributors to this growth being North America, Europe, China and The Middle East. Awards The anime industry has several annual awards that honor the year's best works. Major annual awards in Japan include the Ōfuji Noburō Award, the Mainichi Film Award for Best Animation Film, the Animation Kobe Awards, the Japan Media Arts Festival animation awards, the Tokyo Anime Award and the Japan Academy Prize for Animation of the Year. In the United States, anime films compete in the Crunchyroll Anime Awards. There were also the American Anime Awards, which were designed to recognize excellence in anime titles nominated by the industry, and were held only once in 2006. Anime productions have also been nominated and won awards not exclusively for anime, like the Academy Award for Best Animated Feature or the Golden Bear. Working conditions In recent years the anime industry has been accused by both Japanese and foreign media for underpaying and overworking its animators. In response the Japanese Prime Minister Fumio Kishida promised to improve the working conditions and salary of all animators and creators working in the industry. A few anime studios such as MAPPA have taken actions to improve the working conditions of their employees. Globalization and Cultural Impact Anime has become commercially profitable in Western countries, as demonstrated by early commercially successful Western adaptations of anime, such as Astro Boy and Speed Racer. Early American adaptions in the 1960s made Japan expand into the continental European market, first with productions aimed at European and Japanese children, such as Heidi, Vicky the Viking and Barbapapa, which aired in various countries. Italy, Spain, and France grew a particular interest into Japan's output, due to its cheap selling price and productive output. In fact, Italy imported the most anime outside of Japan. These mass imports influenced anime popularity in South American, Arabic and German markets. The beginning of 1980 saw the introduction of Japanese anime series into the American culture. In the 1990s, Japanese animation slowly gained popularity in America.

In the 1990s, Japanese animation slowly gained popularity in America.

Media companies such as Viz and Mixx began publishing and releasing animation into the American market. The 1988 film Akira is largely credited with popularizing anime in the Western world during the early 1990s, before anime was further popularized by television shows such as Pokémon and Dragon Ball Z in the late 1990s. By 1997, Japanese anime was the fastest-growing genre in the American video industry. The growth of the Internet later provided international audiences an easy way to access Japanese content. Early on, online piracy played a major role in this, through over time many legal alternatives appeared. Since the 2010s various streaming services have become increasingly involved in the production and licensing of anime for the international markets. This is especially the case with net services such as Netflix and Crunchyroll which have large catalogs in Western countries, although as of 2020 anime fans in many developing non-Western countries, such as India and Philippines, have fewer options of obtaining access to legal content, and therefore still turn to online piracy. However beginning with the early 2020s anime has been experiencing yet another boom in global popularity and demand due to the Covid-19 pandemic and streaming services like Netflix, Prime video, Hulu and anime only services like Crunchyroll & Funimation increasing the international availability of the amount of new licensed anime shows as well as the size of their catalogs. Netflix reported that, between October 2019 and September 2020, more than member households worldwide had watched at least one anime title on the platform. Anime titles appeared on the streaming platforms top 10 lists in almost 100 countries within the 1-year period. As of 2021 Japanese anime are the most demanded foreign language shows in the United States accounting for 30.5% of the market share(In comparison, Spanish and Korean shows account for 21% and 11% of the market share). In 2022 the anime series Attack on Titan won the award of "Most in-demand TV series in the world 2021" in the Global TV Demand Awards. Attack on Titan became the first ever non-English language series to earn the title of World’s Most In-Demand TV Show, previously held by only The Walking Dead and Game of Thrones. Rising interest in anime as well as japanese video games has led to an increase of university students in the United Kingdom wanting to get a degree in the Japanese language. Various anime and manga series have influenced Hollywood in the making of numerous famous movies and characters. Hollywood itself has produced live-action adaptations of various anime series such as Ghost in the Shell, Death Note, Dragon Ball Evolution and Cowboy Bebop. However most of these adaptations have been reviewed negatively by both the critics and the audience and have become box-office flops.

However most of these adaptations have been reviewed negatively by both the critics and the audience and have become box-office flops.

The main reasons for the unsuccessfulness of Hollywood's adaptions of anime being the often change of plot and characters from the original source material and the limited capabilities a live-action movie or series can do in comparison to an animated counterpart. One particular exception however is Alita: Battle Angel which has become a moderate commercial success, receiving generally positive reviews from both the critics and the audience for it's visual effects and following the source material. The movie grossed $404 million worldwide, making it directors Robert Rodriguez's highest-grossing film. Anime alongside many other parts of Japanese pop culture has helped Japan to gain a positive worldwide image and improve it's relations with other countries. In 2015 During remarks welcoming Japanese Prime Minister Shinzo Abe to the White House, President Barack Obama thanked Japan for its cultural contributions to the United States by saying: This visit is a celebration of the ties of friendship and family that bind our peoples. I first felt it when I was 6 years old when my mother took me to Japan. I felt it growing up in Hawaii, like communities across our country, home to so many proud Japanese Americans, and Today is also a chance for Americans, especially our young people, to say thank you for all the things we love from Japan. Like karate and karaoke. Manga and anime. And, of course, emojis. In July 2020, after the approval of a Chilean government project in which citizens of Chile would be allowed to withdraw up to 10% of their privately held retirement savings, journalist Pamela Jiles celebrated by running through congress with her arms spread out behind her, imitating the move of many characters of the anime and manga series Naruto. In April 2021 Peruvian politicians Jorge Hugo Romero of the PPC and Milagros Juárez of the UPP cosplayed as anime characters to get the otaku vote. A 2018 survey conducted in 20 countries and territories using a sample consisting of 6,600 respondents held by Dentsu revealed that 34% of all surveyed people found excellency in anime and manga more than other Japanese cultural or technological aspects which makes this mass Japanese media the 3rd most liked "Japanese thing", below japanese cuisine (34.6%) and japanese robotics (35.1%). The advertisement company views anime as a profitable tool for marketing campaigns in foreign countries due it's popularity and high reception. Anime plays a role in driving tourism to Japan. In surveys held by Statista between 2019 and 2020, 24.2% of tourists from the United States, 7.7% of tourists from China and 6.1% of tourists from South Korea said they were motivated to visit Japan because of Japanese popular culture. In a 2021 survey held by Crunchyroll market research, 94% of Gen-Z's and 73% of the general population said that they are familiar with anime.

A 2018 survey conducted in 20 countries and territories using a sample consisting of 6,600 respondents held by Dentsu revealed that 34% of all surveyed people found excellency in anime and manga more than other Japanese cultural or technological aspects which makes this mass Japanese media the 3rd most liked "Japanese thing", below japanese cuisine (34.6%) and japanese robotics (35.1%). The advertisement company views anime as a profitable tool for marketing campaigns in foreign countries due it's popularity and high reception. Anime plays a role in driving tourism to Japan. In surveys held by Statista between 2019 and 2020, 24.2% of tourists from the United States, 7.7% of tourists from China and 6.1% of tourists from South Korea said they were motivated to visit Japan because of Japanese popular culture. In a 2021 survey held by Crunchyroll market research, 94% of Gen-Z's and 73% of the general population said that they are familiar with anime. Fan response Anime clubs gave rise to anime conventions in the 1990s with the "anime boom", a period marked by anime's increased global popularity.

These conventions are dedicated to anime and manga and include elements like cosplay contests and industry talk panels. Cosplay, a portmanteau of "costume play", is not unique to anime and has become popular in contests and masquerades at anime conventions. Japanese culture and words have entered English usage through the popularity of the medium, including otaku, an unflattering Japanese term commonly used in English to denote an obsessive fan of anime and/or manga. Another word that has arisen describing obsessive fans in the United States is wapanese meaning 'white individuals who want to be Japanese', or later known as weeaboo or weeb, individuals who demonstrate an obsession in Japanese anime subculture, a term that originated from abusive content posted on the website 4chan.org. While originally derogatory, the terms "Otaku" and "Weeb" have been reappropriated by some in the anime fandom overtime and today are used by some fans to refer to themselves in a comedic and more positive way. Anime enthusiasts have produced fan fiction and fan art, including computer wallpapers and anime music videos (AMVs). As of the 2020s, many anime fans use social media platforms like YouTube, Facebook, Reddit and Twitter (which has added an entire "anime and manga" category of topics) with online communities and databases such as MyAnimeList to discuss anime, manga and track their progress watching respective series as well as using news outlets such as Anime News Network. Due to anime's increased popularity in recent years, a large number of celebrities such as Elon Musk, BTS and Ariana Grande have come out as anime fans. Anime style One of the key points that made anime different from a handful of Western cartoons is the potential for visceral content. Once the expectation that the aspects of visual intrigue or animation being just for children is put aside, the audience can realize that themes involving violence, suffering, sexuality, pain, and death can all be storytelling elements utilized in anime just as much as other media. However, as anime itself became increasingly popular, its styling has been inevitably the subject of both satire and serious creative productions. South Parks "Chinpokomon" and "Good Times with Weapons" episodes, Adult Swim's Perfect Hair Forever, and Nickelodeon's Kappa Mikey are examples of Western satirical depictions of Japanese culture and anime, but anime tropes have also been satirized by some anime such as KonoSuba. Traditionally only Japanese works have been considered anime, but some works have sparked debate for blurring the lines between anime and cartoons, such as the American anime-style production Avatar: The Last Airbender. These anime-styled works have become defined as anime-influenced animation, in an attempt to classify all anime styled works of non-Japanese origin. Some creators of these works cite anime as a source of inspiration, for example the French production team for Ōban Star-Racers that moved to Tokyo to collaborate with a Japanese production team.

When anime is defined as a "style" rather than as a national product, it leaves open the possibility of anime being produced in other countries, but this has been contentious amongst fans, with John Oppliger stating, "The insistence on referring to original American art as Japanese "anime" or "manga" robs the work of its cultural identity." A U.A.E.-Filipino produced TV series called Torkaizer is dubbed as the "Middle East's First Anime Show", and is currently in production and looking for funding. Netflix has produced multiple anime series in collaboration with Japanese animation studios, and in doing so, has offered a more accessible channel for distribution to Western markets. The web-based series RWBY, produced by Texas-based company Rooster Teeth, is produced using an anime art style, and the series has been described as "anime" by multiple sources. For example, Adweek, in the headline to one of its articles, described the series as "American-made anime", and in another headline, The Huffington Post described it as simply "anime", without referencing its country of origin. In 2013, Monty Oum, the creator of RWBY, said "Some believe just like Scotch needs to be made in Scotland, an American company can't make anime. I think that's a narrow way of seeing it. Anime is an art form, and to say only one country can make this art is wrong." RWBY has been released in Japan with a Japanese language dub; the CEO of Rooster Teeth, Matt Hullum, commented "This is the first time any American-made anime has been marketed to Japan. It definitely usually works the other way around, and we're really pleased about that." Media franchises In Japanese culture and entertainment, media mix is a strategy to disperse content across multiple representations: different broadcast media, gaming technologies, cell phones, toys, amusement parks, and other methods. It is the Japanese term for a transmedia franchise. The term gained its circulation in late 1980s, but the origins of the strategy can be traced back to the 1960s with the proliferation of anime, with its interconnection of media and commodity goods. A number of anime and manga media franchises such as Demon Slayer: Kimetsu no Yaiba, Dragon Ball and Gundam have gained considerable global popularity, and are among the world's highest-grossing media franchises. Pokémon in particular is estimated to be the highest-grossing media franchise of all time.

Ankara Ankara ( , ; ), historically known as Ancyra and Angora, is the capital of Turkey. Located in the central part of Anatolia, the city has a population of 5.1 million in its urban center and over 5.7 million in Ankara Province, making it Turkey's second-largest city after Istanbul. Serving as the capital of the ancient Celtic state of Galatia (280–64 BC), and later of the Roman province with the same name (25 BC–7th century), the city is very old, with various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393 – late 15th century) and then the Angora Vilayet (1867–1922). The historical center of Ankara is a rocky hill rising over the left bank of the Ankara River, a tributary of the Sakarya River. The hill remains crowned by the ruins of Ankara Castle. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture throughout the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti. On 23 April 1920, the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the establishment of the Republic on 29 October 1923, succeeding in this role as the former Turkish capital Istanbul following the fall of the Ottoman Empire. The government is a prominent employer, but Ankara is also an important commercial and industrial city located at the center of Turkey's road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat (the source of mohair), and the Angora cat. The area is also known for its pears, honey and muscat grapes. Although situated in one of the driest regions of Turkey and surrounded mostly by steppe vegetation (except for the forested areas on the southern periphery), Ankara can be considered a green city in terms of green areas per inhabitant, at per head. Etymology The orthography of the name Ankara has varied over the ages. It has been identified with the Hittite cult center Ankuwaš, although this remains a matter of debate. In classical antiquity and during the medieval period, the city was known as Ánkyra (,  "anchor") in Greek and Ancyra in Latin; the Galatian Celtic name was probably a similar variant. Following its annexation by the Seljuk Turks in 1073, the city became known in many European languages as Angora; it was also known in Ottoman Turkish as Engürü. The form "Angora" is preserved in the names of breeds of many different kinds of animals, and in the names of several locations in the US (see Angora).

History The region's history can be traced back to the Bronze Age Hattic civilization, which was succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, and later by the Lydians, Persians, Greeks, Galatians, Romans, Byzantines, and Turks (the Seljuk Sultanate of Rûm, the Ottoman Empire and finally republican Turkey). Ancient history The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was gradually absorbed c. 2000 – 1700 BC by the Indo-European Hittites. The city grew significantly in size and importance under the Phrygians starting around 1000 BC, and experienced a large expansion following the mass migration from Gordion, (the capital of Phrygia), after an earthquake which severely damaged that city around that time. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was actually far older, which accords with present archeological knowledge. Phrygian rule was succeeded first by Lydian and later by Persian rule, though the strongly Phrygian character of the peasantry remained, as evidenced by the gravestones of the much later Roman period. Persian sovereignty lasted until the Persians' defeat at the hands of Alexander the Great who conquered the city in 333 BC. Alexander came from Gordion to Ankara and stayed in the city for a short period. After his death at Babylon in 323 BC and the subsequent division of his empire among his generals, Ankara, and its environs fell into the share of Antigonus. Another important expansion took place under the Greeks of Pontos who came there around 300 BC and developed the city as a trading center for the commerce of goods between the Black Sea ports and Crimea to the north; Assyria, Cyprus, and Lebanon to the south; and Georgia, Armenia and Persia to the east. By that time the city also took its name Ἄγκυρα (Ánkyra, meaning anchor in Greek) which, in slightly modified form, provides the modern name of Ankara. Celtic history In 278 BC, the city, along with the rest of central Anatolia, was occupied by a Celtic group, the Galatians, who were the first to make Ankara one of their main tribal centers, the headquarters of the Tectosages tribe. Other centers were Pessinus, today's Ballıhisar, for the Trocmi tribe, and Tavium, to the east of Ankara, for the Tolistobogii tribe. The city was then known as Ancyra. The Celtic element was probably relatively small in numbers; a warrior aristocracy which ruled over Phrygian-speaking peasants. However, the Celtic language continued to be spoken in Galatia for many centuries. At the end of the 4th century, St. Jerome, a native of Dalmatia, observed that the language spoken around Ankara was very similar to that being spoken in the northwest of the Roman world near Trier. Roman history The city was subsequently passed under the control of the Roman Empire.

At the end of the 4th century, St. Jerome, a native of Dalmatia, observed that the language spoken around Ankara was very similar to that being spoken in the northwest of the Roman world near Trier. Roman history The city was subsequently passed under the control of the Roman Empire.

In 25 BC, Emperor Augustus raised it to the status of a polis and made it the capital city of the Roman province of Galatia. Ankara is famous for the Monumentum Ancyranum (Temple of Augustus and Rome) which contains the official record of the Acts of Augustus, known as the Res Gestae Divi Augusti, an inscription cut in marble on the walls of this temple. The ruins of Ancyra still furnish today valuable bas-reliefs, inscriptions and other architectural fragments. Two other Galatian tribal centers, Tavium near Yozgat, and Pessinus (Balhisar) to the west, near Sivrihisar, continued to be reasonably important settlements in the Roman period, but it was Ancyra that grew into a grand metropolis. An estimated 200,000 people lived in Ancyra in good times during the Roman Empire, a far greater number than was to be the case from after the fall of the Roman Empire until the early 20th century. The small Ankara River ran through the center of the Roman town. It has now been covered and diverted, but it formed the northern boundary of the old town during the Roman, Byzantine and Ottoman periods. Çankaya, the rim of the majestic hill to the south of the present city center, stood well outside the Roman city, but may have been a summer resort. In the 19th century, the remains of at least one Roman villa or large house were still standing not far from where the Çankaya Presidential Residence stands today. To the west, the Roman city extended until the area of the Gençlik Park and Railway Station, while on the southern side of the hill, it may have extended downwards as far as the site presently occupied by Hacettepe University. It was thus a sizeable city by any standards and much larger than the Roman towns of Gaul or Britannia. Ancyra's importance rested on the fact that it was the junction point where the roads in northern Anatolia running north–south and east–west intersected, giving it major strategic importance for Rome's eastern frontier. The great imperial road running east passed through Ankara and a succession of emperors and their armies came this way. They were not the only ones to use the Roman highway network, which was equally convenient for invaders. In the second half of the 3rd century, Ancyra was invaded in rapid succession by the Goths coming from the west (who rode far into the heart of Cappadocia, taking slaves and pillaging) and later by the Arabs. For about a decade, the town was one of the western outposts of one of Palmyrean empress Zenobia in the Syrian Desert, who took advantage of a period of weakness and disorder in the Roman Empire to set up a short-lived state of her own. The town was reincorporated into the Roman Empire under Emperor Aurelian in 272.

In 25 BC, Emperor Augustus raised it to the status of a polis and made it the capital city of the Roman province of Galatia. Ankara is famous for the Monumentum Ancyranum (Temple of Augustus and Rome) which contains the official record of the Acts of Augustus, known as the Res Gestae Divi Augusti, an inscription cut in marble on the walls of this temple. The ruins of Ancyra still furnish today valuable bas-reliefs, inscriptions and other architectural fragments. Two other Galatian tribal centers, Tavium near Yozgat, and Pessinus (Balhisar) to the west, near Sivrihisar, continued to be reasonably important settlements in the Roman period, but it was Ancyra that grew into a grand metropolis. An estimated 200,000 people lived in Ancyra in good times during the Roman Empire, a far greater number than was to be the case from after the fall of the Roman Empire until the early 20th century. The small Ankara River ran through the center of the Roman town. It has now been covered and diverted, but it formed the northern boundary of the old town during the Roman, Byzantine and Ottoman periods. Çankaya, the rim of the majestic hill to the south of the present city center, stood well outside the Roman city, but may have been a summer resort. In the 19th century, the remains of at least one Roman villa or large house were still standing not far from where the Çankaya Presidential Residence stands today. To the west, the Roman city extended until the area of the Gençlik Park and Railway Station, while on the southern side of the hill, it may have extended downwards as far as the site presently occupied by Hacettepe University. It was thus a sizeable city by any standards and much larger than the Roman towns of Gaul or Britannia. Ancyra's importance rested on the fact that it was the junction point where the roads in northern Anatolia running north–south and east–west intersected, giving it major strategic importance for Rome's eastern frontier. The great imperial road running east passed through Ankara and a succession of emperors and their armies came this way.

The tetrarchy, a system of multiple (up to four) emperors introduced by Diocletian (284–305), seems to have engaged in a substantial program of rebuilding and of road construction from Ancyra westwards to Germe and Dorylaeum (now Eskişehir). In its heyday, Roman Ancyra was a large market and trading center but it also functioned as a major administrative capital, where a high official ruled from the city's Praetorium, a large administrative palace or office. During the 3rd century, life in Ancyra, as in other Anatolian towns, seems to have become somewhat militarized in response to the invasions and instability of the town. Byzantine history The city is well known during the 4th century as a center of Christian activity (see also below), due to frequent imperial visits, and through the letters of the pagan scholar Libanius. Bishop Marcellus of Ancyra and Basil of Ancyra were active in the theological controversies of their day, and the city was the site of no less than three church synods in 314, 358 and 375, the latter two in favor of Arianism. The city was visited by Emperor Constans I (r. 337–350) in 347 and 350, Julian (r. 361–363) during his Persian campaign in 362, and Julian's successor Jovian (r. 363–364) in winter 363/364 (he entered his consulship while in the city). After Jovian's death soon after, Valentinian I (r. 364–375) was acclaimed emperor at Ancyra, and in the next year his brother Valens (r. 364–378) used Ancyra as his base against the usurper Procopius. When the province of Galatia was divided sometime in 396/99, Ancyra remained the civil capital of Galatia I, as well as its ecclesiastical center (metropolitan see). Emperor Arcadius (r. 383–408) frequently used the city as his summer residence, and some information about the ecclesiastical affairs of the city during the early 5th century is found in the works of Palladius of Galatia and Nilus of Galatia. In 479, the rebel Marcian attacked the city, without being able to capture it. In 610/11, Comentiolus, brother of Emperor Phocas (r. 602–610), launched his own unsuccessful rebellion in the city against Heraclius (r. 610–641). Ten years later, in 620 or more likely 622, it was captured by the Sassanid Persians during the Byzantine–Sassanid War of 602–628. Although the city returned to Byzantine hands after the end of the war, the Persian presence left traces in the city's archeology, and likely began the process of its transformation from a late antique city to a medieval fortified settlement. In 654, the city was captured for the first time by the Arabs of the Rashidun Caliphate, under Muawiyah, the future founder of the Umayyad Caliphate. At about the same time, the themes were established in Anatolia, and Ancyra became capital of the Opsician Theme, which was the largest and most important theme until it was split up under Emperor Constantine V (r. 741–775); Ancyra then became the capital of the new Bucellarian Theme.

The city was captured at least temporarily by the Umayyad prince Maslama ibn Hisham in 739/40, the last of the Umayyads' territorial gains from the Byzantine Empire. Ancyra was attacked without success by Abbasid forces in 776 and in 798/99. In 805, Emperor Nikephoros I (r. 802–811) strengthened its fortifications, a fact which probably saved it from sack during the large-scale invasion of Anatolia by Caliph Harun al-Rashid in the next year. Arab sources report that Harun and his successor al-Ma'mun (r. 813–833) took the city, but this information is later invention. In 838, however, during the Amorium campaign, the armies of Caliph al-Mu'tasim (r. 833–842) converged and met at the city; abandoned by its inhabitants, Ancara was razed to the ground, before the Arab armies went on to besiege and destroy Amorium. In 859, Emperor Michael III (r. 842–867) came to the city during a campaign against the Arabs, and ordered its fortifications restored. In 872, the city was menaced, but not taken, by the Paulicians under Chrysocheir. The last Arab raid to reach the city was undertaken in 931, by the Abbasid governor of Tarsus, Thamal al-Dulafi, but the city again was not captured. Ecclesiastical history Early Christian martyrs of Ancyra, about whom little is known, included Proklos and Hilarios who were natives of the otherwise unknown nearby village of Kallippi, and suffered repression under the emperor Trajan (98–117). In the 280s we hear of Philumenos, a Christian corn merchant from southern Anatolia, being captured and martyred in Ankara, and Eustathius. As in other Roman towns, the reign of Diocletian marked the culmination of the persecution of the Christians. In 303, Ancyra was one of the towns where the co-emperors Diocletian and his deputy Galerius launched their anti-Christian persecution. In Ancyra, their first target was the 38-year-old Bishop of the town, whose name was Clement. Clement's life describes how he was taken to Rome, then sent back, and forced to undergo many interrogations and hardship before he, and his brother, and various companions were put to death. The remains of the church of St. Clement can be found today in a building just off Işıklar Caddesi in the Ulus district. Quite possibly this marks the site where Clement was originally buried. Four years later, a doctor of the town named Plato and his brother Antiochus also became celebrated martyrs under Galerius. Theodotus of Ancyra is also venerated as a saint. However, the persecution proved unsuccessful and in 314 Ancyra was the center of an important council of the early church; its 25 disciplinary canons constitute one of the most important documents in the early history of the administration of the Sacrament of Penance. The synod also considered ecclesiastical policy for the reconstruction of the Christian Church after the persecutions, and in particular the treatment of lapsi—Christians who had given in to forced paganism (sacrifices) to avoid martyrdom during these persecutions. Though paganism was probably tottering in Ancyra in Clement's day, it may still have been the majority religion.

Though paganism was probably tottering in Ancyra in Clement's day, it may still have been the majority religion.

Twenty years later, Christianity and monotheism had taken its place. Ancyra quickly turned into a Christian city, with a life dominated by monks and priests and theological disputes. The town council or senate gave way to the bishop as the main local figurehead. During the middle of the 4th century, Ancyra was involved in the complex theological disputes over the nature of Christ, and a form of Arianism seems to have originated there. In 362–363, Emperor Julian passed through Ancyra on his way to an ill-fated campaign against the Persians, and according to Christian sources, engaged in a persecution of various holy men. The stone base for a statue, with an inscription describing Julian as "Lord of the whole world from the British Ocean to the barbarian nations", can still be seen, built into the eastern side of the inner circuit of the walls of Ankara Castle. The Column of Julian which was erected in honor of the emperor's visit to the city in 362 still stands today. In 375, Arian bishops met at Ancyra and deposed several bishops, among them St. Gregory of Nyssa. In the late 4th century, Ancyra became something of an imperial holiday resort. After Constantinople became the East Roman capital, emperors in the 4th and 5th centuries would retire from the humid summer weather on the Bosporus to the drier mountain atmosphere of Ancyra. Theodosius II (408–450) kept his court in Ancyra in the summers. Laws issued in Ancyra testify to the time they spent there. The Metropolis of Ancyra continued to be a residential see of the Eastern Orthodox Church until the 20th century, with about 40,000 faithful, mostly Turkish-speaking, but that situation ended as a result of the 1923 Convention Concerning the Exchange of Greek and Turkish Populations. The earlier Armenian genocide put an end to the residential eparchy of Ancyra of the Armenian Catholic Church, which had been established in 1850. It is also a titular metropolis of the Ecumenical Patriarchate of Constantinople. Both the Ancient Byzantine Metropolitan archbishopric and the 'modern' Armenian eparchy are now listed by the Catholic Church as titular sees, with separate apostolic successions. Seljuk and Ottoman history After the Battle of Manzikert in 1071, the Seljuk Turks overran much of Anatolia. By 1073, the Turkish settlers had reached the vicinity of Ancyra, and the city was captured shortly after, at the latest by the time of the rebellion of Nikephoros Melissenos in 1081. In 1101, when the Crusade under Raymond IV of Toulouse arrived, the city had been under Danishmend control for some time. The Crusaders captured the city, and handed it over to the Byzantine emperor Alexios I Komnenos (r. 1081–1118). Byzantine rule did not last long, and the city was captured by the Seljuk Sultanate of Rum at some unknown point; in 1127, it returned to Danishmend control until 1143, when the Seljuks of Rum retook it.

Both the Ancient Byzantine Metropolitan archbishopric and the 'modern' Armenian eparchy are now listed by the Catholic Church as titular sees, with separate apostolic successions. Seljuk and Ottoman history After the Battle of Manzikert in 1071, the Seljuk Turks overran much of Anatolia. By 1073, the Turkish settlers had reached the vicinity of Ancyra, and the city was captured shortly after, at the latest by the time of the rebellion of Nikephoros Melissenos in 1081. In 1101, when the Crusade under Raymond IV of Toulouse arrived, the city had been under Danishmend control for some time. The Crusaders captured the city, and handed it over to the Byzantine emperor Alexios I Komnenos (r. 1081–1118). Byzantine rule did not last long, and the city was captured by the Seljuk Sultanate of Rum at some unknown point; in 1127, it returned to Danishmend control until 1143, when the Seljuks of Rum retook it.

After the Battle of Köse Dağ in 1243, in which the Mongols defeated the Seljuks, most of Anatolia became part of the dominion of the Mongols. Taking advantage of Seljuk decline, a semi-religious cast of craftsmen and trade people named Ahiler chose Angora as their independent city-state in 1290. Orhan I, the second Bey of the Ottoman Empire, captured the city in 1356. Timur defeated Bayezid I at the Battle of Ankara in 1402 and took the city, but in 1403 Angora was again under Ottoman control. The Levant Company maintained a factory in the town from 1639 to 1768. In the 19th century, its population was estimated at 20,000 to 60,000. It was sacked by Egyptians under Ibrahim Pasha in 1832. From 1867 to 1922, the city served as the capital of the Angora Vilayet, which included most of ancient Galatia. Prior to World War I, the town had a British consulate and a population of around 28,000, roughly of whom were Christian. Turkish republican capital Following the Ottoman defeat in World War I, the Ottoman capital Constantinople (modern Istanbul) and much of Anatolia was occupied by the Allies, who planned to share these lands between Armenia, France, Greece, Italy and the United Kingdom, leaving for the Turks the core piece of land in central Anatolia. In response, the leader of the Turkish nationalist movement, Mustafa Kemal Atatürk, established the headquarters of his resistance movement in Angora in 1920. After the Turkish War of Independence was won and the Treaty of Sèvres was superseded by the Treaty of Lausanne (1923), the Turkish nationalists replaced the Ottoman Empire with the Republic of Turkey on 29 October 1923. A few days earlier, Angora had officially replaced Constantinople as the new Turkish capital city, on 13 October 1923, and Republican officials declared that the city's name is Ankara. After Ankara became the capital of the newly founded Republic of Turkey, new development divided the city into an old section, called Ulus, and a new section, called Yenişehir. Ancient buildings reflecting Roman, Byzantine, and Ottoman history and narrow winding streets mark the old section. The new section, now centered on Kızılay Square, has the trappings of a more modern city: wide streets, hotels, theaters, shopping malls, and high-rises. Government offices and foreign embassies are also located in the new section. Ankara has experienced a phenomenal growth since it was made Turkey's capital in 1923, when it was "a small town of no importance". In 1924, the year after the government had moved there, Ankara had about 35,000 residents. By 1927 there were 44,553 residents and by 1950 the population had grown to 286,781. Ankara continued to grow rapidly during the latter half of the 20th century and eventually outranked Izmir as Turkey's second-largest city, after Istanbul. Ankara's urban population reached 4,587,558 in 2014, while the population of Ankara Province reached 5,150,072 in 2015. After 1930, it became known officially in Western languages as Ankara.

After the late 1930s the public stopped using the name "Angora". Presidential Palace of Turkey is situated in Ankara. This building serves as the main residence of the president. Economy and infrastructure The city has exported mohair (from the Angora goat) and Angora wool (from the Angora rabbit) internationally for centuries. In the 19th century, the city also exported substantial amounts of goat and cat skins, gum, wax, honey, berries, and madder root. It was connected to Istanbul by railway before the First World War, continuing to export mohair, wool, berries, and grain. The Central Anatolia Region is one of the primary locations of grape and wine production in Turkey, and Ankara is particularly famous for its Kalecik Karası and Muscat grapes; and its Kavaklıdere wine, which is produced in the Kavaklıdere neighborhood within the Çankaya district of the city. Ankara is also famous for its pears. Another renowned natural product of Ankara is its indigenous type of honey (Ankara Balı) which is known for its light color and is mostly produced by the Atatürk Forest Farm and Zoo in the Gazi district, and by other facilities in the Elmadağ, Çubuk and Beypazarı districts. Çubuk-1 and Çubuk-2 dams on the Çubuk Brook in Ankara were among the first dams constructed in the Turkish Republic. Ankara is the center of the state-owned and private Turkish defence and aerospace companies, where the industrial plants and headquarters of the Turkish Aerospace Industries, MKE, ASELSAN, HAVELSAN, ROKETSAN, FNSS, Nurol Makina, and numerous other firms are located. Exports to foreign countries from these defense and aerospace firms have steadily increased in the past decades. The IDEF in Ankara is one of the largest international expositions of the global arms industry. A number of the global automotive companies also have production facilities in Ankara, such as the German bus and truck manufacturer MAN SE.

Monthly mean temperatures range from in January to in July, with an annual mean of . Demographics Ankara had a population of 75,000 in 1927. As of 2019, Ankara Province has a population of 5,639,076. When Ankara became the capital of the Republic of Turkey in 1923, it was designated as a planned city for 500,000 future inhabitants. During the 1920s, 1930s and 1940s, the city grew in a planned and orderly pace. However, from the 1950s onward, the city grew much faster than envisioned, because unemployment and poverty forced people to migrate from the countryside into the city in order to seek a better standard of living. As a result, many illegal houses called gecekondu were built around the city, causing the unplanned and uncontrolled urban landscape of Ankara, as not enough planned housing could be built fast enough. Although precariously built, the vast majority of them have electricity, running water and modern household amenities. Nevertheless, many of these gecekondus have been replaced by huge public housing projects in the form of tower blocks such as Elvankent, Eryaman and Güzelkent; and also as mass housing compounds for military and civil service accommodation. Although many gecekondus still remain, they too are gradually being replaced by mass housing compounds, as empty land plots in the city of Ankara for new construction projects are becoming impossible to find. Çorum and Yozgat, which are located in Central Anatolia and whose population is decreasing, are the provinces with the highest net migration to Ankara. About one third of the Central Anatolia population of 15,608,868 people resides in Ankara. The population of Ankara has a higher education level than the country average. According to 2008 data, 15-years-higher literacy rate creates 88% of the total provincial population (91% in men and 86% in women). This ratio was 83% for Turkey (88% males, 79% females). This difference is particularly evident in the university educated segment of the population. The ratio of university and high school graduates to total population is 10.6% in Ankara, while 5.4% in Turkey. Transportation The Electricity, Gas, Bus General Directorate (EGO) operates the Ankara Metro and other forms of public transportation. Ankara is served by a suburban rail named Ankaray (A1) and three subway lines (M1, M2, M3) of the Ankara Metro with about 300,000 total daily commuters, while an additional subway line (M4) is under construction. A long gondola lift with four stations connects the district of Şentepe to the Yenimahalle metro station. The Ankara Central Station is a major rail hub in Turkey. The Turkish State Railways operates passenger train service from Ankara to other major cities, such as: Istanbul, Eskişehir, Balıkesir, Kütahya, İzmir, Kayseri, Adana, Kars, Elâzığ, Malatya, Diyarbakır, Karabük, Zonguldak and Sivas. Commuter rail also runs between the stations of Sincan and Kayaş. On 13 March 2009, the new Yüksek Hızlı Tren (YHT) high-speed rail service began operation between Ankara and Eskişehir. On 23 August 2011, another YHT high-speed line commercially started its service between Ankara and Konya.

Ankara public transportation statistics The average amount of time people spend commuting on public transit in Ankara on a weekday is 71 minutes. 17% of public transit passengers, ride for more than two hours every day. The average amount of time people wait at a stop or station for public transit is sixteen minutes, while 28% of users wait for over twenty minutes on average every day. The average distance people usually ride in a single trip with public transit is , while 27% travel for over in a single direction. Politics Since 8 April 2019, the Mayor of Ankara is Mansur Yavaş from the Republican People's Party (CHP), who won the mayoral election in 2019. Ankara is politically a triple battleground between the ruling conservative Justice and Development Party (AKP), the opposition Kemalist center-left Republican People's Party (CHP) and the nationalist far-right Nationalist Movement Party (MHP). The province of Ankara is divided into 25 districts. The CHP's key and almost only political stronghold in Ankara lies within the central area of Çankaya, which is the city's most populous district. While the CHP has always gained between 60 and 70% of the vote in Çankaya since 2002, political support elsewhere throughout Ankara is minimal. The high population within Çankaya, as well as Yenimahalle to an extent, has allowed the CHP to take overall second place behind the AKP in both local and general elections, with the MHP a close third, despite the fact that the MHP is politically stronger than the CHP in almost every other district. Overall, the AKP enjoys the most support throughout the city. The electorate of Ankara thus tend to vote in favor of the political right, far more so than the other main cities of Istanbul and İzmir. In retrospect, the 2013–14 protests against the AKP government were particularly strong in Ankara, proving to be fatal on multiple occasions.The city suffered from a series of terrorist attacks in 2015 and 2016, most notably on 10 October 2015; 17 February 2016; 13 March 2016; and 15 July 2016. Melih Gökçek was the Metropolitan Mayor of Ankara between 1994 and 2017. Initially elected in the 1994 local elections, he was re-elected in 1999, 2004 and 2009. In the 2014 local elections, Gökçek stood for a fifth term. The MHP's metropolitan mayoral candidate for the 2009 local elections, Mansur Yavaş, stood as the CHP's candidate against Gökçek in 2014. In a heavily controversial election, Gökçek was declared the winner by just 1% ahead of Yavaş amid allegations of systematic electoral fraud. With the Supreme Electoral Council and courts rejecting his appeals, Yavaş declared his intention to take the irregularities to the European Court of Human Rights. Although Gökçek was inaugurated for a fifth term, most election observers believe that Yavaş was the winner of the election.

While the CHP has always gained between 60 and 70% of the vote in Çankaya since 2002, political support elsewhere throughout Ankara is minimal. The high population within Çankaya, as well as Yenimahalle to an extent, has allowed the CHP to take overall second place behind the AKP in both local and general elections, with the MHP a close third, despite the fact that the MHP is politically stronger than the CHP in almost every other district. Overall, the AKP enjoys the most support throughout the city. The electorate of Ankara thus tend to vote in favor of the political right, far more so than the other main cities of Istanbul and İzmir. In retrospect, the 2013–14 protests against the AKP government were particularly strong in Ankara, proving to be fatal on multiple occasions.The city suffered from a series of terrorist attacks in 2015 and 2016, most notably on 10 October 2015; 17 February 2016; 13 March 2016; and 15 July 2016. Melih Gökçek was the Metropolitan Mayor of Ankara between 1994 and 2017. Initially elected in the 1994 local elections, he was re-elected in 1999, 2004 and 2009. In the 2014 local elections, Gökçek stood for a fifth term. The MHP's metropolitan mayoral candidate for the 2009 local elections, Mansur Yavaş, stood as the CHP's candidate against Gökçek in 2014. In a heavily controversial election, Gökçek was declared the winner by just 1% ahead of Yavaş amid allegations of systematic electoral fraud. With the Supreme Electoral Council and courts rejecting his appeals, Yavaş declared his intention to take the irregularities to the European Court of Human Rights. Although Gökçek was inaugurated for a fifth term, most election observers believe that Yavaş was the winner of the election.

Visitors to the "Çiftlik" (farm) as it is affectionately called by Ankarans, can sample such famous products of the farm such as old-fashioned beer and ice cream, fresh dairy products and meat rolls/kebaps made on charcoal, at a traditional restaurant (Merkez Lokantası, Central Restaurant), cafés and other establishments scattered around the farm.

Turkish Angoras are one of the ancient, naturally occurring cat breeds, having originated in Ankara and its surrounding region in central Anatolia. They mostly have a white, silky, medium to long length coat, no undercoat and a fine bone structure. There seems to be a connection between the Angora Cats and Persians, and the Turkish Angora is also a distant cousin of the Turkish Van. Although they are known for their shimmery white coat, there are more than twenty varieties including black, blue and reddish fur. They come in tabby and tabby-white, along with smoke varieties, and are in every color other than pointed, lavender, and cinnamon (all of which would indicate breeding to an outcross.) Eyes may be blue, green, or amber, or even one blue and one amber or green. The W gene which is responsible for the white coat and blue eye is closely related to the hearing ability, and the presence of a blue eye can indicate that the cat is deaf to the side the blue eye is located. However, a great many blue and odd-eyed white cats have normal hearing, and even deaf cats lead a very normal life if kept indoors. Ears are pointed and large, eyes are almond shaped and the head is massive with a two plane profile. Another characteristic is the tail, which is often kept parallel to the back.

These include the following, several of them being among the most reputable in the country: Ankara University Atılım University Başkent University Bilkent University Çankaya University Gazi University Gülhane Military Medical Academy Hacettepe University İpek University Middle East Technical University TED University TOBB University of Economics and Technology Turkish Aeronautical Association University Turkish Military Academy Turkish National Police Academy Ufuk University Yıldırım Beyazıt University Fauna Angora cat Ankara is home to a world-famous domestic cat breed – the Turkish Angora, called Ankara kedisi (Ankara cat) in Turkish. Turkish Angoras are one of the ancient, naturally occurring cat breeds, having originated in Ankara and its surrounding region in central Anatolia. They mostly have a white, silky, medium to long length coat, no undercoat and a fine bone structure. There seems to be a connection between the Angora Cats and Persians, and the Turkish Angora is also a distant cousin of the Turkish Van. Although they are known for their shimmery white coat, there are more than twenty varieties including black, blue and reddish fur. They come in tabby and tabby-white, along with smoke varieties, and are in every color other than pointed, lavender, and cinnamon (all of which would indicate breeding to an outcross.) Eyes may be blue, green, or amber, or even one blue and one amber or green. The W gene which is responsible for the white coat and blue eye is closely related to the hearing ability, and the presence of a blue eye can indicate that the cat is deaf to the side the blue eye is located. However, a great many blue and odd-eyed white cats have normal hearing, and even deaf cats lead a very normal life if kept indoors. Ears are pointed and large, eyes are almond shaped and the head is massive with a two plane profile. Another characteristic is the tail, which is often kept parallel to the back.

Angora goat The Angora goat () is a breed of domestic goat that originated in Ankara and its surrounding region in central Anatolia. This breed was first mentioned in the time of Moses, roughly in 1500 BC. The first Angora goats were brought to Europe by Charles V, Holy Roman Emperor, about 1554, but, like later imports, were not very successful. Angora goats were first introduced in the United States in 1849 by Dr. James P. Davis. Seven adult goats were a gift from Sultan Abdülmecid I in appreciation for his services and advice on the raising of cotton. The fleece taken from an Angora goat is called mohair. A single goat produces between of hair per year. Angoras are shorn twice a year, unlike sheep, which are shorn only once. Angoras have high nutritional requirements due to their rapid hair growth. A poor quality diet will curtail mohair development. The United States, Turkey, and South Africa are the top producers of mohair. For a long period of time, Angora goats were bred for their white coat. In 1998, the Colored Angora Goat Breeders Association was set up to promote breeding of colored Angoras. Today, Angora goats produce white, black (deep black to greys and silver), red (the color fades significantly as the goat gets older), and brownish fiber. Angora goats were depicted on the reverse of the Turkish 50 lira banknotes of 1938–1952. Angora rabbit The Angora rabbit () is a variety of domestic rabbit bred for its long, soft hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara and its surrounding region in central Anatolia, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid-18th century, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 20th century. They are bred largely for their long Angora wool, which may be removed by shearing, combing, or plucking (gently pulling loose wool.) Angoras are bred mainly for their wool because it is silky and soft. They have a humorous appearance, as they oddly resemble a fur ball. Most are calm and docile but should be handled carefully. Grooming is necessary to prevent the fiber from matting and felting on the rabbit. A condition called "wool block" is common in Angora rabbits and should be treated quickly. Sometimes they are shorn in the summer as the long fur can cause the rabbits to overheat.

Arabic Arabic (, or , or ) is a Semitic language that first emerged in the 1st to 4th centuries CE. It is the lingua franca of the Arab world and the liturgical language of Islam. It is named after the Arabs, a term initially used to describe peoples living in the Arabian Peninsula bounded by eastern Egypt in the west, Mesopotamia in the east, and the Anti-Lebanon mountains and northern Syria in the north, as perceived by ancient Greek geographers. The ISO assigns language codes to 32 varieties of Arabic, including its standard form, Modern Standard Arabic, also referred to as Literary Arabic, which is modernized Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as ( "the eloquent Arabic") or simply (). Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. Arabic, in its Modern Standard Arabic form, is an official language of 26 states and 1 disputed territory, the third most after English and French; it is also the liturgical language of the religion of Islam, since the Quran and the Hadiths were written in Classical Arabic. During the early Middle Ages, Arabic was a major vehicle of culture in the Mediterranean region, especially in science, mathematics and philosophy. As a result, many European languages have also borrowed many words from it. Arabic influence, mainly in vocabulary, is seen in European languages—mainly Spanish and to a lesser extent Portuguese, Catalan, and Sicilian—owing to both the proximity of Christian European and Muslim Arabized civilizations and the long-lasting Muslim culture and Arabic language presence, mainly in Southern Iberia, during the Al-Andalus era. The Maltese language is a Semitic language developed from a dialect of Arabic and written in the Latin alphabet. The Balkan languages, including Greek and Bulgarian, have also acquired a significant number of words of Arabic origin through contact with Ottoman Turkish. Arabic has influenced many other languages around the globe throughout its history especially languages of Muslim cultures and countries that were conquered by Muslims. Some of the most influenced languages are Persian, Turkish, Hindustani (Hindi and Urdu), Kashmiri, Kurdish, Bosnian, Kazakh, Bengali, Malay (Indonesian and Malaysian), Maldivian, Pashto, Punjabi, Albanian, Armenian, Azerbaijani, Sicilian, Spanish, Greek, Bulgarian, Tagalog, Sindhi, Odia Hebrew and Hausa and some languages in parts of Africa. Conversely, Arabic has borrowed words from other languages, including Aramaic as well as Hebrew, Latin, Greek, Persian and to a lesser extent Turkish (due to the Ottoman Empire), English and French (due to their colonization of the Levant) and other Semitic languages such as Abyssinian. Arabic is the liturgical language of 1.9 billion Muslims, and Arabic is one of six official languages of the United Nations.

All varieties of Arabic combined are spoken by perhaps as many as 422 million speakers (native and non-native) in the Arab world, making it the fifth most spoken language in the world, and the fourth most used language on the internet in terms of users. In 2011, Bloomberg Businessweek ranked Arabic the fourth most useful language for business, after English, Standard Mandarin Chinese, and French. Arabic is written with the Arabic alphabet, which is an abjad script and is written from right to left, although the spoken varieties are sometimes written in ASCII Latin from left to right with no standardized orthography. Classification Arabic is usually, but not universally, classified as a Central Semitic language. It is related to languages in other subgroups of the Semitic language group (Northwest Semitic, South Semitic, East Semitic, West Semitic), such as Aramaic, Syriac, Hebrew, Ugaritic, Phoenician, Canaanite, Amorite, Ammonite, Eblaite, epigraphic Ancient North Arabian, epigraphic Ancient South Arabian, Ethiopic, Modern South Arabian, and numerous other dead and modern languages. Linguists still differ as to the best classification of Semitic language sub-groups. The Semitic languages changed a great deal between Proto-Semitic and the emergence of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: The conversion of the suffix-conjugated stative formation (jalas-) into a past tense. The conversion of the prefix-conjugated preterite-tense formation (yajlis-) into a present tense. The elimination of other prefix-conjugated mood/aspect forms (e.g., a present tense formed by doubling the middle root, a perfect formed by infixing a after the first root consonant, probably a jussive formed by a stress shift) in favor of new moods formed by endings attached to the prefix-conjugation forms (e.g., -u for indicative, -a for subjunctive, no ending for jussive, -an or -anna for energetic). The development of an internal passive. There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of the northern Hejaz. These features are evidence of common descent from a hypothetical ancestor, Proto-Arabic.

In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family (e.g. Southern Thamudic) were spoken. It is also believed that the ancestors of the Modern South Arabian languages (non-Central Semitic languages) were also spoken in southern Arabia at this time.

In Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested. In eastern Arabia, inscriptions in a script derived from ASA attest to a language known as Hasaitic. Finally, on the northwestern frontier of Arabia, various languages known to scholars as Thamudic B, Thamudic D, Safaitic, and Hismaic are attested. The last two share important isoglosses with later forms of Arabic, leading scholars to theorize that Safaitic and Hismaic are in fact early forms of Arabic and that they should be considered Old Arabic. Linguists generally believe that "Old Arabic" (a collection of related dialects that constitute the precursor of Arabic) first emerged around the 1st century CE. Previously, the earliest attestation of Old Arabic was thought to be a single 1st century CE inscription in Sabaic script at Qaryat Al-Faw, in southern present-day Saudi Arabia. However, this inscription does not participate in several of the key innovations of the Arabic language group, such as the conversion of Semitic mimation to nunation in the singular. It is best reassessed as a separate language on the Central Semitic dialect continuum. It was also thought that Old Arabic coexisted alongside—and then gradually displaced--epigraphic Ancient North Arabian (ANA), which was theorized to have been the regional tongue for many centuries. ANA, despite its name, was considered a very distinct language, and mutually unintelligible, from "Arabic". Scholars named its variant dialects after the towns where the inscriptions were discovered (Dadanitic, Taymanitic, Hismaic, Safaitic). However, most arguments for a single ANA language or language family were based on the shape of the definite article, a prefixed h-. It has been argued that the h- is an archaism and not a shared innovation, and thus unsuitable for language classification, rendering the hypothesis of an ANA language family untenable. Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to the fact that they participate in the innovations common to all forms of Arabic.The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel, and dated to around 125 CE. This is followed by the Namara inscription, an epitaph of the Lakhmid king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From the 4th to the 6th centuries, the Nabataean script evolves into the Arabic script recognizable from the early Islamic era. There are inscriptions in an undotted, 17-letter Arabic script dating to the 6th century CE, found at four locations in Syria (Zabad, Jabal 'Usays, Harran, Umm al-Jimaal). The oldest surviving papyrus in Arabic dates to 643 CE, and it uses dots to produce the modern 28-letter Arabic alphabet. The language of that papyrus and of the Qur'an are referred to by linguists as "Quranic Arabic", as distinct from its codification soon thereafter into "Classical Arabic".

Old Hejazi and Classical Arabic In late pre-Islamic times, a transdialectal and transcommunal variety of Arabic emerged in the Hejaz which continued living its parallel life after literary Arabic had been institutionally standardized in the 2nd and 3rd century of the Hijra, most strongly in Judeo-Christian texts, keeping alive ancient features eliminated from the "learned" tradition (Classical Arabic). This variety and both its classicizing and "lay" iterations have been termed Middle Arabic in the past, but they are thought to continue an Old Higazi register. It is clear that the orthography of the Qur'an was not developed for the standardized form of Classical Arabic; rather, it shows the attempt on the part of writers to record an archaic form of Old Higazi. In the late 6th century AD, a relatively uniform intertribal "poetic koine" distinct from the spoken vernaculars developed based on the Bedouin dialects of Najd, probably in connection with the court of al-Ḥīra. During the first Islamic century, the majority of Arabic poets and Arabic-writing persons spoke Arabic as their mother tongue. Their texts, although mainly preserved in far later manuscripts, contain traces of non-standardized Classical Arabic elements in morphology and syntax. Standardization Abu al-Aswad al-Du'ali (c. 603–689) is credited with standardizing Arabic grammar, or an-naḥw ( "the way"), and pioneering a system of diacritics to differentiate consonants ( nuqat l-i'jām "pointing for non-Arabs") and indicate vocalization ( at-tashkil). Al-Khalil ibn Ahmad al-Farahidi (718 – 786) compiled the first Arabic dictionary, Kitāb al-'Ayn ( "The Book of the Letter ع"), and is credited with establishing the rules of Arabic prosody. Al-Jahiz (776-868) proposed to Al-Akhfash al-Akbar an overhaul of the grammar of Arabic, but it would not come to pass two centuries. The standardization of Arabic reached completion around the end of the 8th century. The first comprehensive description of the ʿarabiyya "Arabic", Sībawayhi's al-Kitāb, is based first of all upon a corpus of poetic texts, in addition to Qur'an usage and Bedouin informants whom he considered to be reliable speakers of the ʿarabiyya. Spread Arabic spread with the spread of Islam. Following the early Muslim conquests, Arabic gained vocabulary from Middle Persian and Turkish. In the early Abbasid period, many Classical Greek terms entered Arabic through translations carried out at Baghdad's House of Wisdom. By the 8th century, knowledge of Classical Arabic had become an essential prerequisite for rising into the higher classes throughout the Islamic world, both for Muslims and non-Muslims. For example, Maimonides, the Andalusi Jewish philosopher, authored works in Judeo-Arabic—Arabic written in Hebrew script—including his famous The Guide for the Perplexed ( Dalālat al-ḥāʾirīn). Development Ibn Jinni of Mosul, a pioneer in phonology, wrote prolifically in the 10th century on Arabic morphology and phonology in works such as Kitāb Al-Munṣif, Kitāb Al-Muḥtasab, and .

Neo-Arabic Charles Ferguson's koine theory (Ferguson 1959) claims that the modern Arabic dialects collectively descend from a single military koine that sprang up during the Islamic conquests; this view has been challenged in recent times. Ahmad al-Jallad proposes that there were at least two considerably distinct types of Arabic on the eve of the conquests: Northern and Central (Al-Jallad 2009). The modern dialects emerged from a new contact situation produced following the conquests. Instead of the emergence of a single or multiple koines, the dialects contain several sedimentary layers of borrowed and areal features, which they absorbed at different points in their linguistic histories. According to Veersteegh and Bickerton, colloquial Arabic dialects arose from pidginized Arabic formed from contact between Arabs and conquered peoples. Pidginization and subsequent creolization among Arabs and arabized peoples could explain relative morphological and phonological simplicity of vernacular Arabic compared to Classical and MSA. In around the 11th and 12th centuries in al-Andalus, the zajal and muwashah poetry forms developed in the dialectical Arabic of Cordoba and the Maghreb. Nahda The Nahda was a cultural and especially literary renaissance of the 19th century in which writers sought "to fuse Arabic and European forms of expression." According to James L. Gelvin, "Nahda writers attempted to simplify the Arabic language and script so that it might be accessible to a wider audience." In the wake of the industrial revolution and European hegemony and colonialism, pioneering Arabic presses, such as the Amiri Press established by Muhammad Ali (1819), dramatically changed the diffusion and consumption of Arabic literature and publications. Rifa'a al-Tahtawi proposed the establishment of in 1836 and led a translation campaign that highlighted the need for a lexical injection in Arabic, to suit concepts of the industrial and post-industrial age. In response, a number of Arabic academies modeled after the Académie française were established with the aim of developing standardized additions to the Arabic lexicon to suit these transformations, first in Damascus (1919), then in Cairo (1932), Baghdad (1948), Rabat (1960), Amman (1977), (1993), and Tunis (1993). In 1997, a bureau of Arabization standardization was added to the Educational, Cultural, and Scientific Organization of the Arab League. These academies and organizations have worked toward the Arabization of the sciences, creating terms in Arabic to describe new concepts, toward the standardization of these new terms throughout the Arabic-speaking world, and toward the development of Arabic as a world language. This gave rise to what Western scholars call Modern Standard Arabic. From the 1950s, Arabization became a postcolonial nationalist policy in countries such as Tunisia, Algeria, Morocco, and Sudan. Classical, Modern Standard and spoken Arabic Arabic usually refers to Standard Arabic, which Western linguists divide into Classical Arabic and Modern Standard Arabic. It could also refer to any of a variety of regional vernacular Arabic dialects, which are not necessarily mutually intelligible. Classical Arabic is the language found in the Quran, used from the period of Pre-Islamic Arabia to that of the Abbasid Caliphate.

Classical Arabic is prescriptive, according to the syntactic and grammatical norms laid down by classical grammarians (such as Sibawayh) and the vocabulary defined in classical dictionaries (such as the Lisān al-ʻArab). Modern Standard Arabic (MSA) largely follows the grammatical standards of Classical Arabic and uses much of the same vocabulary. However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties and has adopted certain new constructions and vocabulary from the spoken varieties. Much of the new vocabulary is used to denote concepts that have arisen in the industrial and post-industrial era, especially in modern times. Due to its grounding in Classical Arabic, Modern Standard Arabic is removed over a millennium from everyday speech, which is construed as a multitude of dialects of this language. These dialects and Modern Standard Arabic are described by some scholars as not mutually comprehensible. The former are usually acquired in families, while the latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children. The relation between Modern Standard Arabic and these dialects is sometimes compared to that of Classical Latin and Vulgar Latin vernaculars (which became Romance languages) in medieval and early modern Europe. This view though does not take into account the widespread use of Modern Standard Arabic as a medium of audiovisual communication in today's mass media—a function Latin has never performed. MSA is the variety used in most current, printed Arabic publications, spoken by some of the Arabic media across North Africa and the Middle East, and understood by most educated Arabic speakers. "Literary Arabic" and "Standard Arabic" ( ) are less strictly defined terms that may refer to Modern Standard Arabic or Classical Arabic. Some of the differences between Classical Arabic (CA) and Modern Standard Arabic (MSA) are as follows: Certain grammatical constructions of CA that have no counterpart in any modern vernacular dialect (e.g., the energetic mood) are almost never used in Modern Standard Arabic. Case distinctions are very rare in Arabic vernaculars. As a result, MSA is generally composed without case distinctions in mind, and the proper cases are added after the fact, when necessary. Because most case endings are noted using final short vowels, which are normally left unwritten in the Arabic script, it is unnecessary to determine the proper case of most words. The practical result of this is that MSA, like English and Standard Chinese, is written in a strongly determined word order and alternative orders that were used in CA for emphasis are rare. In addition, because of the lack of case marking in the spoken varieties, most speakers cannot consistently use the correct endings in extemporaneous speech. As a result, spoken MSA tends to drop or regularize the endings except when reading from a prepared text. The numeral system in CA is complex and heavily tied in with the case system.

MSA is the variety used in most current, printed Arabic publications, spoken by some of the Arabic media across North Africa and the Middle East, and understood by most educated Arabic speakers. "Literary Arabic" and "Standard Arabic" ( ) are less strictly defined terms that may refer to Modern Standard Arabic or Classical Arabic. Some of the differences between Classical Arabic (CA) and Modern Standard Arabic (MSA) are as follows: Certain grammatical constructions of CA that have no counterpart in any modern vernacular dialect (e.g., the energetic mood) are almost never used in Modern Standard Arabic. Case distinctions are very rare in Arabic vernaculars. As a result, MSA is generally composed without case distinctions in mind, and the proper cases are added after the fact, when necessary. Because most case endings are noted using final short vowels, which are normally left unwritten in the Arabic script, it is unnecessary to determine the proper case of most words. The practical result of this is that MSA, like English and Standard Chinese, is written in a strongly determined word order and alternative orders that were used in CA for emphasis are rare. In addition, because of the lack of case marking in the spoken varieties, most speakers cannot consistently use the correct endings in extemporaneous speech. As a result, spoken MSA tends to drop or regularize the endings except when reading from a prepared text. The numeral system in CA is complex and heavily tied in with the case system.

This system is never used in MSA, even in the most formal of circumstances; instead, a significantly simplified system is used, approximating the system of the conservative spoken varieties. MSA uses much Classical vocabulary (e.g., 'to go') that is not present in the spoken varieties, but deletes Classical words that sound obsolete in MSA. In addition, MSA has borrowed or coined many terms for concepts that did not exist in Quranic times, and MSA continues to evolve. Some words have been borrowed from other languages—notice that transliteration mainly indicates spelling and not real pronunciation (e.g., 'film' or 'democracy'). However, the current preference is to avoid direct borrowings, preferring to either use loan translations (e.g., 'branch', also used for the branch of a company or organization; 'wing', is also used for the wing of an airplane, building, air force, etc. ), or to coin new words using forms within existing roots ( 'apoptosis', using the root m/w/t 'death' put into the Xth form, or 'university', based on 'to gather, unite'; 'republic', based on 'multitude'). An earlier tendency was to redefine an older word although this has fallen into disuse (e.g., 'telephone' < 'invisible caller (in Sufism)'; 'newspaper' < 'palm-leaf stalk'). Colloquial or dialectal Arabic refers to the many national or regional varieties which constitute the everyday spoken language and evolved from Classical Arabic. Colloquial Arabic has many regional variants; geographically distant varieties usually differ enough to be mutually unintelligible, and some linguists consider them distinct languages. However, research indicates a high degree of mutual intelligibility between closely related Arabic variants for native speakers listening to words, sentences, and texts; and between more distantly related dialects in interactional situations. The varieties are typically unwritten. They are often used in informal spoken media, such as soap operas and talk shows, as well as occasionally in certain forms of written media such as poetry and printed advertising. The only variety of modern Arabic to have acquired official language status is Maltese, which is spoken in (predominantly Catholic) Malta and written with the Latin script. It is descended from Classical Arabic through Siculo-Arabic, but is not mutually intelligible with any other variety of Arabic. Most linguists list it as a separate language rather than as a dialect of Arabic. Even during Muhammad's lifetime, there were dialects of spoken Arabic. Muhammad spoke in the dialect of Mecca, in the western Arabian peninsula, and it was in this dialect that the Quran was written down. However, the dialects of the eastern Arabian peninsula were considered the most prestigious at the time, so the language of the Quran was ultimately converted to follow the eastern phonology. It is this phonology that underlies the modern pronunciation of Classical Arabic.

The phonological differences between these two dialects account for some of the complexities of Arabic writing, most notably the writing of the glottal stop or hamzah (which was preserved in the eastern dialects but lost in western speech) and the use of (representing a sound preserved in the western dialects but merged with in eastern speech). Language and dialect The sociolinguistic situation of Arabic in modern times provides a prime example of the linguistic phenomenon of diglossia, which is the normal use of two separate varieties of the same language, usually in different social situations. Tawleed is the process of giving a new shade of meaning to an old classical word. For example, al-hatif lexicographically, means the one whose sound is heard but whose person remains unseen. Now the term al-hatif is used for a telephone. Therefore, the process of tawleed can express the needs of modern civilization in a manner that would appear to be originally Arabic. In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native dialects, which depending on the region may be mutually unintelligible. Some of these dialects can be considered to constitute separate languages which may have “sub-dialects” of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within the same sentence. Arabic speakers often improve their familiarity with other dialects via music or film. The issue of whether Arabic is one language or many languages is politically charged, in the same way it is for the varieties of Chinese, Hindi and Urdu, Serbian and Croatian, Scots and English, etc. In contrast to speakers of Hindi and Urdu who claim they cannot understand each other even when they can, speakers of the varieties of Arabic will claim they can all understand each other even when they cannot. While there is a minimum level of comprehension between all Arabic dialects, this level can increase or decrease based on geographic proximity: for example, Levantine and Gulf speakers understand each other much better than they do speakers from the Maghreb. The issue of diglossia between spoken and written language is a significant complicating factor: A single written form, significantly different from any of the spoken varieties learned natively, unites a number of sometimes divergent spoken forms. For political reasons, Arabs mostly assert that they all speak a single language, despite significant issues of mutual incomprehensibility among differing spoken versions. From a linguistic standpoint, it is often said that the various spoken varieties of Arabic differ among each other collectively about as much as the Romance languages. This is an apt comparison in a number of ways. The period of divergence from a single spoken form is similar—perhaps 1500 years for Arabic, 2000 years for the Romance languages.

Also, while it is comprehensible to people from the Maghreb, a linguistically innovative variety such as Moroccan Arabic is essentially incomprehensible to Arabs from the Mashriq, much as French is incomprehensible to Spanish or Italian speakers but relatively easily learned by them. This suggests that the spoken varieties may linguistically be considered separate languages. Influence of Arabic on other languages The influence of Arabic has been most important in Islamic countries, because it is the language of the Islamic sacred book, the Quran. Arabic is also an important source of vocabulary for languages such as Amharic, Azerbaijani, Baluchi, Bengali, Berber, Bosnian, Chaldean, Chechen, Chittagonian, Croatian, Dagestani, Dhivehi, English, German, Gujarati, Hausa, Hindi, Kazakh, Kurdish, Kutchi, Kyrgyz, Malay (Malaysian and Indonesian), Pashto, Persian, Punjabi, Rohingya, Romance languages (French, Catalan, Italian, Portuguese, Sicilian, Spanish, etc.) Saraiki, Sindhi, Somali, Sylheti, Swahili, Tagalog, Tigrinya, Turkish, Turkmen, Urdu, Uyghur, Uzbek, Visayan and Wolof, as well as other languages in countries where these languages are spoken.Modern Hebrew has been also influenced by Arabic especially during the process of revival, as MSA was used as a source for modern Hebrew vocabulary and roots, as well as much of Modern Hebrew's slang. The Education Minister of France Jean-Michel Blanquer has emphasized the learning and usage of Arabic in French schools. In addition, English has many Arabic loanwords, some directly, but most via other Mediterranean languages. Examples of such words include admiral, adobe, alchemy, alcohol, algebra, algorithm, alkaline, almanac, amber, arsenal, assassin, candy, carat, cipher, coffee, cotton, ghoul, hazard, jar, kismet, lemon, loofah, magazine, mattress, sherbet, sofa, sumac, tariff, and zenith. Other languages such as Maltese and Kinubi derive ultimately from Arabic, rather than merely borrowing vocabulary or grammatical rules. Terms borrowed range from religious terminology (like Berber taẓallit, "prayer", from salat ( )), academic terms (like Uyghur mentiq, "logic"), and economic items (like English coffee) to placeholders (like Spanish fulano, "so-and-so"), everyday terms (like Hindustani lekin, "but", or Spanish taza and French tasse, meaning "cup"), and expressions (like Catalan a betzef, "galore, in quantity"). Most Berber varieties (such as Kabyle), along with Swahili, borrow some numbers from Arabic. Most Islamic religious terms are direct borrowings from Arabic, such as (salat), "prayer", and (imam), "prayer leader." In languages not directly in contact with the Arab world, Arabic loanwords are often transferred indirectly via other languages rather than being transferred directly from Arabic. For example, most Arabic loanwords in Hindustani and Turkish entered through Persian. Older Arabic loanwords in Hausa were borrowed from Kanuri. Most Arabic loanwords in Yoruba entered through Hausa. Arabic words also made their way into several West African languages as Islam spread across the Sahara. Variants of Arabic words such as kitāb ("book") have spread to the languages of African groups who had no direct contact with Arab traders. Since, throughout the Islamic world, Arabic occupied a position similar to that of Latin in Europe, many of the Arabic concepts in the fields of science, philosophy, commerce, etc.

were coined from Arabic roots by non-native Arabic speakers, notably by Aramaic and Persian translators, and then found their way into other languages. This process of using Arabic roots, especially in Kurdish and Persian, to translate foreign concepts continued through to the 18th and 19th centuries, when swaths of Arab-inhabited lands were under Ottoman rule. Influence of other languages on Arabic The most important sources of borrowings into (pre-Islamic) Arabic are from the related (Semitic) languages Aramaic, which used to be the principal, international language of communication throughout the ancient Near and Middle East, and Ethiopic. In addition, many cultural, religious and political terms have entered Arabic from Iranian languages, notably Middle Persian, Parthian, and (Classical) Persian, and Hellenistic Greek (kīmiyāʼ has as origin the Greek khymia, meaning in that language the melting of metals; see Roger Dachez, Histoire de la Médecine de l'Antiquité au XXe siècle, Tallandier, 2008, p. 251), alembic (distiller) from ambix (cup), almanac (climate) from almenichiakon (calendar). (For the origin of the last three borrowed words, see Alfred-Louis de Prémare, Foundations of Islam, Seuil, L'Univers Historique, 2002.) Some Arabic borrowings from Semitic or Persian languages are, as presented in De Prémare's above-cited book: madīnah/medina (مدينة, city or city square), a word of Aramaic origin “madenta” (in which it means "a state"). jazīrah (جزيرة), as in the well-known form الجزيرة "Al-Jazeera," means "island" and has its origin in the Syriac ܓܙܝܪܗ gazarta. lāzaward (لازورد) is taken from Persian لاژورد lājvard, the name of a blue stone, lapis lazuli. This word was borrowed in several European languages to mean (light) blue – azure in English, azur in French and azul in Portuguese and Spanish. A comprehensive overview of the influence of other languages on Arabic is found in Lucas & Manfredi (2020). Arabic alphabet and nationalism There have been many instances of national movements to convert Arabic script into Latin script or to Romanize the language. Currently, the only language derived from Classical Arabic to use Latin script is Maltese. Lebanon The Beirut newspaper La Syrie pushed for the change from Arabic script to Latin letters in 1922. The major head of this movement was Louis Massignon, a French Orientalist, who brought his concern before the Arabic Language Academy in Damascus in 1928. Massignon's attempt at Romanization failed as the Academy and population viewed the proposal as an attempt from the Western world to take over their country. Sa'id Afghani, a member of the Academy, mentioned that the movement to Romanize the script was a Zionist plan to dominate Lebanon. Said Akl created a Latin-based alphabet for Lebanese and used it in a newspaper he founded, Lebnaan, as well as in some books he wrote. Egypt After the period of colonialism in Egypt, Egyptians were looking for a way to reclaim and re-emphasize Egyptian culture.

Some Arabic borrowings from Semitic or Persian languages are, as presented in De Prémare's above-cited book: madīnah/medina (مدينة, city or city square), a word of Aramaic origin “madenta” (in which it means "a state"). jazīrah (جزيرة), as in the well-known form الجزيرة "Al-Jazeera," means "island" and has its origin in the Syriac ܓܙܝܪܗ gazarta. lāzaward (لازورد) is taken from Persian لاژورد lājvard, the name of a blue stone, lapis lazuli. This word was borrowed in several European languages to mean (light) blue – azure in English, azur in French and azul in Portuguese and Spanish. A comprehensive overview of the influence of other languages on Arabic is found in Lucas & Manfredi (2020). Arabic alphabet and nationalism There have been many instances of national movements to convert Arabic script into Latin script or to Romanize the language. Currently, the only language derived from Classical Arabic to use Latin script is Maltese. Lebanon The Beirut newspaper La Syrie pushed for the change from Arabic script to Latin letters in 1922. The major head of this movement was Louis Massignon, a French Orientalist, who brought his concern before the Arabic Language Academy in Damascus in 1928. Massignon's attempt at Romanization failed as the Academy and population viewed the proposal as an attempt from the Western world to take over their country. Sa'id Afghani, a member of the Academy, mentioned that the movement to Romanize the script was a Zionist plan to dominate Lebanon. Said Akl created a Latin-based alphabet for Lebanese and used it in a newspaper he founded, Lebnaan, as well as in some books he wrote. Egypt After the period of colonialism in Egypt, Egyptians were looking for a way to reclaim and re-emphasize Egyptian culture.

As a result, some Egyptians pushed for an Egyptianization of the Arabic language in which the formal Arabic and the colloquial Arabic would be combined into one language and the Latin alphabet would be used. There was also the idea of finding a way to use Hieroglyphics instead of the Latin alphabet, but this was seen as too complicated to use. A scholar, Salama Musa agreed with the idea of applying a Latin alphabet to Arabic, as he believed that would allow Egypt to have a closer relationship with the West. He also believed that Latin script was key to the success of Egypt as it would allow for more advances in science and technology. This change in alphabet, he believed, would solve the problems inherent with Arabic, such as a lack of written vowels and difficulties writing foreign words that made it difficult for non-native speakers to learn. Ahmad Lutfi As Sayid and Muhammad Azmi, two Egyptian intellectuals, agreed with Musa and supported the push for Romanization. The idea that Romanization was necessary for modernization and growth in Egypt continued with Abd Al-Aziz Fahmi in 1944. He was the chairman for the Writing and Grammar Committee for the Arabic Language Academy of Cairo. However, this effort failed as the Egyptian people felt a strong cultural tie to the Arabic alphabet. In particular, the older Egyptian generations believed that the Arabic alphabet had strong connections to Arab values and history, due to the long history of the Arabic alphabet (Shrivtiel, 189) in Muslim societies. The language of the Quran and its influence on poetry The Quran introduced a new way of writing to the world. People began studying and applying the unique styles they learned from the Quran to not only their own writing, but also their culture. Writers studied the unique structure and format of the Quran in order to identify and apply the figurative devices and their impact on the reader. Quran's figurative devices The Quran inspired musicality in poetry through the internal rhythm of the verses. The arrangement of words, how certain sounds create harmony, and the agreement of rhymes create the sense of rhythm within each verse. At times, the chapters of the Quran only have the rhythm in common. The repetition in the Quran introduced the true power and impact repetition can have in poetry. The repetition of certain words and phrases made them appear more firm and explicit in the Quran. The Quran uses constant metaphors of blindness and deafness to imply unbelief. Metaphors were not a new concept to poetry, however the strength of extended metaphors was. The explicit imagery in the Quran inspired many poets to include and focus on the feature in their own work. The poet ibn al-Mu'tazz wrote a book regarding the figures of speech inspired by his study of the Quran. Poet Badr Shakir al-Sayyab expresses his political opinion in his work through imagery inspired by the forms of more harsher imagery used in the Quran.

The Quran uses figurative devices in order to express the meaning in the most beautiful form possible. The study of the pauses in the Quran as well as other rhetoric allow it to be approached in a multiple ways. Structure Although the Quran is known for its fluency and harmony, the structure can be best described as not always being inherently chronological, but can also flow thematically instead (the chapters in the Quran have segments that flow in chronological order, however segments can transition into other segments not related in chronology, but could be related in topic). The suras, also known as chapters of the Quran, are not placed in chronological order. The only constant in their structure is that the longest are placed first and shorter ones follow. The topics discussed in the chapters can also have no direct relation to each other (as seen in many suras) and can share in their sense of rhyme. The Quran introduces to poetry the idea of abandoning order and scattering narratives throughout the text. Harmony is also present in the sound of the Quran. The elongations and accents present in the Quran create a harmonious flow within the writing. Unique sound of the Quran recited, due to the accents, create a deeper level of understanding through a deeper emotional connection. The Quran is written in a language that is simple and understandable by people. The simplicity of the writing inspired later poets to write in a more clear and clear-cut style. The words of the Quran, although unchanged, are to this day understandable and frequently used in both formal and informal Arabic. The simplicity of the language makes memorizing and reciting the Quran a slightly easier task. Culture and the Quran The writer al-Khattabi explains how culture is a required element to create a sense of art in work as well as understand it. He believes that the fluency and harmony which the Quran possess are not the only elements that make it beautiful and create a bond between the reader and the text. While a lot of poetry was deemed comparable to the Quran in that it is equal to or better than the composition of the Quran, a debate rose that such statements are not possible because humans are incapable of composing work comparable to the Quran. Because the structure of the Quran made it difficult for a clear timeline to be seen, Hadith were the main source of chronological order. The Hadith were passed down from generation to generation and this tradition became a large resource for understanding the context. Poetry after the Quran began possessing this element of tradition by including ambiguity and background information to be required to understand the meaning. After the Quran came down to the people, the tradition of memorizing the verses became present. It is believed that the greater the amount of the Quran memorized, the greater the faith.

As technology improved over time, hearing recitations of the Quran became more available as well as more tools to help memorize the verses. The tradition of Love Poetry served as a symbolic representation of a Muslim's desire for a closer contact with their Lord. While the influence of the Quran on Arabic poetry is explained and defended by numerous writers, some writers such as Al-Baqillani believe that poetry and the Quran are in no conceivable way related due to the uniqueness of the Quran. Poetry's imperfections prove his points that they cannot be compared with the fluency the Quran holds. Arabic and Islam Classical Arabic is the language of poetry and literature (including news); it is also mainly the language of the Quran. Classical Arabic is closely associated with the religion of Islam because the Quran was written in it. Most of the world's Muslims do not speak Classical Arabic as their native language, but many can read the Quranic script and recite the Quran. Among non-Arab Muslims, translations of the Quran are most often accompanied by the original text. At present, Modern Standard Arabic (MSA) is also used in modernized versions of literary forms of the Quran. Some Muslims present a monogenesis of languages and claim that the Arabic language was the language revealed by God for the benefit of mankind and the original language as a prototype system of symbolic communication, based upon its system of triconsonantal roots, spoken by man from which all other languages were derived, having first been corrupted. Judaism has a similar account with the Tower of Babel. Dialects and descendants Colloquial Arabic is a collective term for the spoken dialects of Arabic used throughout the Arab world, which differ radically from the literary language. The main dialectal division is between the varieties within and outside of the Arabian peninsula, followed by that between sedentary varieties and the much more conservative Bedouin varieties. All the varieties outside of the Arabian peninsula (which include the large majority of speakers) have many features in common with each other that are not found in Classical Arabic. This has led researchers to postulate the existence of a prestige koine dialect in the one or two centuries immediately following the Arab conquest, whose features eventually spread to all newly conquered areas. These features are present to varying degrees inside the Arabian peninsula. Generally, the Arabian peninsula varieties have much more diversity than the non-peninsula varieties, but these have been understudied. Within the non-peninsula varieties, the largest difference is between the non-Egyptian North African dialects (especially Moroccan Arabic) and the others. Moroccan Arabic in particular is hardly comprehensible to Arabic speakers east of Libya (although the converse is not true, in part due to the popularity of Egyptian films and other media).

One factor in the differentiation of the dialects is influence from the languages previously spoken in the areas, which have typically provided a significant number of new words and have sometimes also influenced pronunciation or word order; however, a much more significant factor for most dialects is, as among Romance languages, retention (or change of meaning) of different classical forms. Thus Iraqi aku, Levantine fīh and North African kayən all mean 'there is', and all come from Classical Arabic forms (yakūn, fīhi, kā'in respectively), but now sound very different. Examples Transcription is a broad IPA transcription, so minor differences were ignored for easier comparison. Also, the pronunciation of Modern Standard Arabic differs significantly from region to region. Koiné According to Charles A. Ferguson, the following are some of the characteristic features of the koiné that underlies all the modern dialects outside the Arabian peninsula. Although many other features are common to most or all of these varieties, Ferguson believes that these features in particular are unlikely to have evolved independently more than once or twice and together suggest the existence of the koine: Loss of the dual number except on nouns, with consistent plural agreement (cf. feminine singular agreement in plural inanimates). Change of a to i in many affixes (e.g., non-past-tense prefixes ti- yi- ni-; wi- 'and'; il- 'the'; feminine -it in the construct state). Loss of third-weak verbs ending in w (which merge with verbs ending in y). Reformation of geminate verbs, e.g., 'I untied' → . Conversion of separate words lī 'to me', laka 'to you', etc. into indirect-object clitic suffixes. Certain changes in the cardinal number system, e.g., 'five days' → , where certain words have a special plural with prefixed t. Loss of the feminine elative (comparative). Adjective plurals of the form 'big' → . Change of nisba suffix > . Certain lexical items, e.g., 'bring' < 'come with'; 'see'; 'what' (or similar) < 'which thing'; (relative pronoun). Merger of and . Dialect groups Egyptian Arabic is spoken by around 53 million people in Egypt (55 million worldwide). It is one of the most understood varieties of Arabic, due in large part to the widespread distribution of Egyptian films and television shows throughout the Arabic-speaking world Levantine Arabic includes North Levantine Arabic, South Levantine Arabic and Cypriot Arabic. It is spoken by about 21 million people in Lebanon, Syria, Jordan, Palestine, Israel, Cyprus and Turkey. Lebanese Arabic is a variety of Levantine Arabic spoken primarily in Lebanon. Jordanian Arabic is a continuum of mutually intelligible varieties of Levantine Arabic spoken by the population of the Kingdom of Jordan. Palestinian Arabic is a name of several dialects of the subgroup of Levantine Arabic spoken by the Palestinians in Palestine, by Arab citizens of Israel and in most Palestinian populations around the world.

It also forms the basis of Maltese via the extinct Sicilian Arabic dialect. Maghrebi Arabic is very hard to understand for Arabic speakers from the Mashriq or Mesopotamia, the most comprehensible being Libyan Arabic and the most difficult Moroccan Arabic. The others such as Algerian Arabic can be considered in between the two in terms of difficulty. Libyan Arabic spoken in Libya and neighboring countries. Tunisian Arabic spoken in Tunisia and North-eastern Algeria Algerian Arabic spoken in Algeria Judeo-Algerian Arabic was spoken by Jews in Algeria until 1962 Moroccan Arabic spoken in Morocco Hassaniya Arabic (3 million speakers), spoken in Mauritania, Western Sahara, some parts of the Azawad in northern Mali, southern Morocco and south-western Algeria. Andalusian Arabic, spoken in Spain until the 16th century. Siculo-Arabic (Sicilian Arabic), was spoken in Sicily and Malta between the end of the 9th century and the end of the 12th century and eventually evolved into the Maltese language. Maltese, spoken on the island of Malta, is the only fully separate standardized language to have originated from an Arabic dialect (the extinct Siculo-Arabic dialect), with independent literary norms. Maltese has evolved independently of Modern Standard Arabic and its varieties into a standardized language over the past 800 years in a gradual process of Latinisation. Maltese is therefore considered an exceptional descendant of Arabic that has no diglossic relationship with Standard Arabic or Classical Arabic. Maltese is also different from Arabic and other Semitic languages since its morphology has been deeply influenced by Romance languages, Italian and Sicilian. It is also the only Semitic language written in the Latin script. In terms of basic everyday language, speakers of Maltese are reported to be able to understand less than a third of what is said to them in Tunisian Arabic, which is related to Siculo-Arabic, whereas speakers of Tunisian are able to understand about 40% of what is said to them in Maltese. This asymmetric intelligibility is considerably lower than the mutual intelligibility found between Maghrebi Arabic dialects. Maltese has its own dialects, with urban varieties of Maltese being closer to Standard Maltese than rural varieties. Mesopotamian Arabic, spoken by about 41.2 million people in Iraq (where it is called "Aamiyah"), eastern Syria and southwestern Iran (Khuzestan) and in the southeastern of Turkey (in the eastern Mediterranean, Southeastern Anatolia Region) North Mesopotamian Arabic is a spoken north of the Hamrin Mountains in Iraq, in western Iran, northern Syria, and in southeastern Turkey (in the eastern Mediterranean Region, Southeastern Anatolia Region, and southern Eastern Anatolia Region). Judeo-Mesopotamian Arabic, also known as Iraqi Judeo Arabic and Yahudic, is a variety of Arabic spoken by Iraqi Jews of Mosul. Baghdad Arabic is the Arabic dialect spoken in Baghdad, and the surrounding cities and it is a subvariety of Mesopotamian Arabic. Baghdad Jewish Arabic is the dialect spoken by the Iraqi Jews of Baghdad. South Mesopotamian Arabic (Basrawi dialect) is the dialect spoken in southern Iraq, such as Basra, Dhi Qar and Najaf.

It also forms the basis of Maltese via the extinct Sicilian Arabic dialect. Maghrebi Arabic is very hard to understand for Arabic speakers from the Mashriq or Mesopotamia, the most comprehensible being Libyan Arabic and the most difficult Moroccan Arabic. The others such as Algerian Arabic can be considered in between the two in terms of difficulty. Libyan Arabic spoken in Libya and neighboring countries.

Its emphatic counterpart was considered by Arabs to be the most unusual sound in Arabic (Hence the Classical Arabic's appellation or "language of the "); for most modern dialects, it has become an emphatic stop with loss of the laterality or with complete loss of any pharyngealization or velarization, . (The classical pronunciation of pharyngealization still occurs in the Mehri language, and the similar sound without velarization, , exists in other Modern South Arabian languages.) Other changes may also have happened. Classical Arabic pronunciation is not thoroughly recorded and different reconstructions of the sound system of Proto-Semitic propose different phonetic values. One example is the emphatic consonants, which are pharyngealized in modern pronunciations but may have been velarized in the eighth century and glottalized in Proto-Semitic. Reduction of and between vowels occurs in a number of circumstances and is responsible for much of the complexity of third-weak ("defective") verbs. Early Akkadian transcriptions of Arabic names shows that this reduction had not yet occurred as of the early part of the 1st millennium BC. The Classical Arabic language as recorded was a poetic koine that reflected a consciously archaizing dialect, chosen based on the tribes of the western part of the Arabian Peninsula, who spoke the most conservative variants of Arabic. Even at the time of Muhammed and before, other dialects existed with many more changes, including the loss of most glottal stops, the loss of case endings, the reduction of the diphthongs and into monophthongs , etc. Most of these changes are present in most or all modern varieties of Arabic. An interesting feature of the writing system of the Quran (and hence of Classical Arabic) is that it contains certain features of Muhammad's native dialect of Mecca, corrected through diacritics into the forms of standard Classical Arabic. Among these features visible under the corrections are the loss of the glottal stop and a differing development of the reduction of certain final sequences containing : Evidently, final became as in the Classical language, but final became a different sound, possibly (rather than again in the Classical language). This is the apparent source of the alif maqṣūrah 'restricted alif' where a final is reconstructed: a letter that would normally indicate or some similar high-vowel sound, but is taken in this context to be a logical variant of alif and represent the sound . Although Classical Arabic was a unitary language and is now used in Quran, its pronunciation varies somewhat from country to country and from region to region within a country. It is influenced by colloquial dialects. Literary Arabic The "colloquial" spoken dialects of Arabic are learned at home and constitute the native languages of Arabic speakers. "Formal" Modern Standard Arabic is learned at school; although many speakers have a native-like command of the language, it is technically not the native language of any speakers.

Both varieties can be both written and spoken, although the colloquial varieties are rarely written down and the formal variety is spoken mostly in formal circumstances, e.g., in radio and TV broadcasts, formal lectures, parliamentary discussions and to some extent between speakers of different colloquial dialects. Even when the literary language is spoken, however, it is normally only spoken in its pure form when reading a prepared text out loud and communication between speakers of different colloquial dialects. When speaking extemporaneously (i.e. making up the language on the spot, as in a normal discussion among people), speakers tend to deviate somewhat from the strict literary language in the direction of the colloquial varieties. In fact, there is a continuous range of "in-between" spoken varieties: from nearly pure Modern Standard Arabic (MSA), to a form that still uses MSA grammar and vocabulary but with significant colloquial influence, to a form of the colloquial language that imports a number of words and grammatical constructions in MSA, to a form that is close to pure colloquial but with the "rough edges" (the most noticeably "vulgar" or non-Classical aspects) smoothed out, to pure colloquial. The particular variant (or register) used depends on the social class and education level of the speakers involved and the level of formality of the speech situation. Often it will vary within a single encounter, e.g., moving from nearly pure MSA to a more mixed language in the process of a radio interview, as the interviewee becomes more comfortable with the interviewer. This type of variation is characteristic of the diglossia that exists throughout the Arabic-speaking world. Although Modern Standard Arabic (MSA) is a unitary language, its pronunciation varies somewhat from country to country and from region to region within a country. The variation in individual "accents" of MSA speakers tends to mirror corresponding variations in the colloquial speech of the speakers in question, but with the distinguishing characteristics moderated somewhat. It is important in descriptions of "Arabic" phonology to distinguish between pronunciation of a given colloquial (spoken) dialect and the pronunciation of MSA by these same speakers. Although they are related, they are not the same. For example, the phoneme that derives from Classical Arabic has many different pronunciations in the modern spoken varieties, e.g., including the proposed original . Speakers whose native variety has either or will use the same pronunciation when speaking MSA. Even speakers from Cairo, whose native Egyptian Arabic has , normally use when speaking MSA. The of Persian Gulf speakers is the only variant pronunciation which isn't found in MSA; is used instead, but may use [j] in MSA for comfortable pronunciation. Another reason of different pronunciations is influence of colloquial dialects.

The differentiation of pronunciation of colloquial dialects is the influence from other languages previously spoken and some still presently spoken in the regions, such as Coptic in Egypt, Berber, Punic, or Phoenician in North Africa, Himyaritic, Modern South Arabian, and Old South Arabian in Yemen and Oman, and Aramaic and Canaanite languages (including Phoenician) in the Levant and Mesopotamia. Another example: Many colloquial varieties are known for a type of vowel harmony in which the presence of an "emphatic consonant" triggers backed allophones of nearby vowels (especially of the low vowels , which are backed to in these circumstances and very often fronted to in all other circumstances). In many spoken varieties, the backed or "emphatic" vowel allophones spread a fair distance in both directions from the triggering consonant; in some varieties (most notably Egyptian Arabic), the "emphatic" allophones spread throughout the entire word, usually including prefixes and suffixes, even at a distance of several syllables from the triggering consonant. Speakers of colloquial varieties with this vowel harmony tend to introduce it into their MSA pronunciation as well, but usually with a lesser degree of spreading than in the colloquial varieties. (For example, speakers of colloquial varieties with extremely long-distance harmony may allow a moderate, but not extreme, amount of spreading of the harmonic allophones in their MSA speech, while speakers of colloquial varieties with moderate-distance harmony may only harmonize immediately adjacent vowels in MSA.) Vowels Modern Standard Arabic has six pure vowels (while most modern dialects have eight pure vowels which includes the long vowels ), with short and corresponding long vowels . There are also two diphthongs: and . The pronunciation of the vowels differs from speaker to speaker, in a way that tends to reflect the pronunciation of the corresponding colloquial variety. Nonetheless, there are some common trends. Most noticeable is the differing pronunciation of and , which tend towards fronted , or in most situations, but a back in the neighborhood of emphatic consonants. Some accents and dialects, such as those of the Hejaz region, have an open or a central in all situations. The vowel varies towards too. Listen to the final vowel in the recording of at the beginning of this article, for example. The point is, Arabic has only three short vowel phonemes, so those phonemes can have a very wide range of allophones. The vowels and are often affected somewhat in emphatic neighborhoods as well, with generally more back or centralized allophones, but the differences are less great than for the low vowels. The pronunciation of short and tends towards and , respectively, in many dialects. The definition of both "emphatic" and "neighborhood" vary in ways that reflect (to some extent) corresponding variations in the spoken dialects. Generally, the consonants triggering "emphatic" allophones are the pharyngealized consonants ; ; and , if not followed immediately by . Frequently, the fricatives also trigger emphatic allophones; occasionally also the pharyngeal consonants (the former more than the latter).

The differentiation of pronunciation of colloquial dialects is the influence from other languages previously spoken and some still presently spoken in the regions, such as Coptic in Egypt, Berber, Punic, or Phoenician in North Africa, Himyaritic, Modern South Arabian, and Old South Arabian in Yemen and Oman, and Aramaic and Canaanite languages (including Phoenician) in the Levant and Mesopotamia. Another example: Many colloquial varieties are known for a type of vowel harmony in which the presence of an "emphatic consonant" triggers backed allophones of nearby vowels (especially of the low vowels , which are backed to in these circumstances and very often fronted to in all other circumstances). In many spoken varieties, the backed or "emphatic" vowel allophones spread a fair distance in both directions from the triggering consonant; in some varieties (most notably Egyptian Arabic), the "emphatic" allophones spread throughout the entire word, usually including prefixes and suffixes, even at a distance of several syllables from the triggering consonant. Speakers of colloquial varieties with this vowel harmony tend to introduce it into their MSA pronunciation as well, but usually with a lesser degree of spreading than in the colloquial varieties. (For example, speakers of colloquial varieties with extremely long-distance harmony may allow a moderate, but not extreme, amount of spreading of the harmonic allophones in their MSA speech, while speakers of colloquial varieties with moderate-distance harmony may only harmonize immediately adjacent vowels in MSA.) Vowels Modern Standard Arabic has six pure vowels (while most modern dialects have eight pure vowels which includes the long vowels ), with short and corresponding long vowels . There are also two diphthongs: and . The pronunciation of the vowels differs from speaker to speaker, in a way that tends to reflect the pronunciation of the corresponding colloquial variety. Nonetheless, there are some common trends. Most noticeable is the differing pronunciation of and , which tend towards fronted , or in most situations, but a back in the neighborhood of emphatic consonants. Some accents and dialects, such as those of the Hejaz region, have an open or a central in all situations. The vowel varies towards too. Listen to the final vowel in the recording of at the beginning of this article, for example. The point is, Arabic has only three short vowel phonemes, so those phonemes can have a very wide range of allophones. The vowels and are often affected somewhat in emphatic neighborhoods as well, with generally more back or centralized allophones, but the differences are less great than for the low vowels. The pronunciation of short and tends towards and , respectively, in many dialects.

Many dialects have multiple emphatic allophones of each vowel, depending on the particular nearby consonants. In most MSA accents, emphatic coloring of vowels is limited to vowels immediately adjacent to a triggering consonant, although in some it spreads a bit farther: e.g., 'time'; 'homeland'; 'downtown' (sometimes or similar). In a non-emphatic environment, the vowel in the diphthong is pronounced or : hence 'sword' but 'summer'. However, in accents with no emphatic allophones of (e.g., in the Hejaz), the pronunciation or occurs in all situations. Consonants The phoneme is represented by the Arabic letter () and has many standard pronunciations. is characteristic of north Algeria, Iraq, and most of the Arabian peninsula but with an allophonic in some positions; occurs in most of the Levant and most of North Africa; and is used in most of Egypt and some regions in Yemen and Oman. Generally this corresponds with the pronunciation in the colloquial dialects. In some regions in Sudan and Yemen, as well as in some Sudanese and Yemeni dialects, it may be either or , representing the original pronunciation of Classical Arabic. Foreign words containing may be transcribed with , , , , , or , mainly depending on the regional spoken variety of Arabic or the commonly diacriticized Arabic letter. In northern Egypt, where the Arabic letter () is normally pronounced , a separate phoneme , which may be transcribed with , occurs in a small number of mostly non-Arabic loanwords, e.g., 'jacket'. () can be pronounced as . In some places of Maghreb it can be also pronounced as . and () are velar, post-velar, or uvular. In many varieties, () are epiglottal in Western Asia. is pronounced as velarized in الله , the name of God, q.e. Allah, when the word follows a, ā, u or ū (after i or ī it is unvelarized: bismi l–lāh ). Some speakers velarize other occurrences of in MSA, in imitation of their spoken dialects. The emphatic consonant was actually pronounced , or possibly —either way, a highly unusual sound. The medieval Arabs actually termed their language 'the language of the Ḍād' (the name of the letter used for this sound), since they thought the sound was unique to their language. (In fact, it also exists in a few other minority Semitic languages, e.g., Mehri.) Arabic has consonants traditionally termed "emphatic" (), which exhibit simultaneous pharyngealization as well as varying degrees of velarization (depending on the region), so they may be written with the "Velarized or pharyngealized" diacritic () as: . This simultaneous articulation is described as "Retracted Tongue Root" by phonologists. In some transcription systems, emphasis is shown by capitalizing the letter, for example, is written ; in others the letter is underlined or has a dot below it, for example, . Vowels and consonants can be phonologically short or long. Long (geminate) consonants are normally written doubled in Latin transcription (i.e. bb, dd, etc. ), reflecting the presence of the Arabic diacritic mark , which indicates doubled consonants.
