Future tense

In grammar, a future tense (abbreviated ) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French aimera, meaning "will love", derived from the verb aimer ("love"). English does not have a future tense formed by verb inflection in this way, although it has a number of ways to express the future, particularly the construction with the auxiliary verb will or shall or is/am/are going to and grammarians differ in whether they describe such constructions as representing a future tense in English.

The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration.

Expressions
The nature of the future, necessarily uncertain and at varying distances ahead, means that the speaker may refer to future events with the modality either of probability (what the speaker expects to happen) or intent (what the speaker plans to make happen). Whether future expression is realis or irrealis depends not so much on an objective ontological notion of future reality, but rather on the degree of the speaker's conviction that the event will in fact come about.

In many languages there is no grammatical (morphological or syntactic) indication of future tense. Future meaning is supplied by the context, with the use of temporal adverbs such as "later", "next year", etc. Such adverbs (in particular words meaning "tomorrow" and "then") sometimes develop into grammaticalized future tense markers. (A tense used to refer specifically to occurrences taking place on the following day is called a crastinal tense.)

In other languages, mostly of European origin, specific markers indicate futurity. These structures constitute a future tense. In many cases, an auxiliary verb is used, as in English, where futurity is often indicated by the modal auxiliary will (or shall). However, some languages combine such an auxiliary with the main verb to produce a simple (one-word, morphological) future tense. This is the origin of the future tense in Western Romance languages such as French and Italian (see below).

A given language may have more than one way to express futurity. English, for example, often refers to future events using present tense forms or other structures such as the going-to future, besides the canonical form with will/shall. In addition, the verb forms used for the future tense can also be used to express other types of meaning; English again provides examples of this (see English modal verbs for the various meanings that both will and shall can have besides simply expressing futurity).

Expressions of relative tense
It is sometimes possible to mark the time of an occurrence as being in the past or future not relative to the present moment (the moment of speaking), but relative to a time of reference, which can itself be in the past or future (or in some hypothetical reality) relative to the present moment. (See relative tense.) Thus an occurrence may be marked as taking place in the "past of the future", "future of the past", etc. (For the "past of the past", see pluperfect.)

The past of the future, marking an occurrence expected to take place before some future reference time, is typically marked by a future perfect form (in languages that have such a form), as in the English "I shall have finished by tomorrow afternoon."

The "future of the past" may be expressed in various ways in English. It is possible to use would in its capacity as the past tense of the future marker will (see English modal verbs and future-in-the-past); for example: "The match started at midday but would not end until the evening." It is also possible to use the past tense of other expressions that express future reference, as in "I was going to wait"; "I was to wait"; "I was about to wait." Such expressions can also be put into other tenses and moods (and non-finite forms), to achieve future reference in hypothetical and future situations, e.g., "I would be going to take part if ..."; "I shall be about to leave." More examples can be found in the section Expressions of relative future in the article on the going-to future.

Germanic languages 
In Germanic languages, including English, a common expression of the future is using the present tense, with the futurity expressed using words that imply future action (I go to Berlin tomorrow or I am going to Berlin tomorrow). There is no simple (morphological) future tense as such. However, the future can also be expressed by employing an auxiliary construction that combines certain present tense auxiliary verbs with the simple infinitive (stem) of the main verb. These auxiliary forms vary between the languages. Other, generally more informal, expressions of futurity use an auxiliary with the compound infinitive of the main verb (as with the English is going to ...).

English
English grammar provides a number of ways to indicate the future nature of an occurrence. Some argue that English does not have a future tense—that is, a grammatical form that always indicates futurity—nor does it have a mandatory form for the expression of futurity. However, there are several generally accepted ways to indicate futurity in English, and some of them—particularly those that use will or shall—are frequently described as future tense.

The will/shall future consists of the modal verb will or shall together with the bare infinitive of the main verb, as in "He will win easily" or "I shall do it when time permits". (Prescriptive grammarians prefer will in the second and third persons and shall in the first person, reversing the forms to express obligation or determination, but in practice shall and will are generally used interchangeably, with will being more common. For details see shall and will.) The meaning of this construction is close to that expressed by the future tense in other languages. However the same construction with will or shall can have other meanings that do not indicate futurity, or else indicate some modality in addition to futurity (as in "He will make rude remarks", meaning he has a habit of doing so, or, "You shall act on my behalf", giving an order). For details of these meanings, see the sections on will and shall in the article on English modal verbs.

The form of the will/shall future described above is frequently called the simple future (or future simple). Other constructions provide additional auxiliaries that express particular aspects: the future progressive (or future continuous) as in "He will be working"; the future perfect as in "They will have finished"; and the future perfect progressive as in "You will have been practising." For detail on these, see the relevant sections of Uses of English verb forms. (For more on expressions of relative tense, such as the future perfect, see also the section  above.)

Several other English constructions commonly refer to the future:
 Present tense forms, as in "The train leaves at five," or, "My cousins arrive tomorrow." Since these grammatical forms are used more canonically to refer to present situations, they are not generally described as future tense; in sentences like those just given they may be described as "present tense with future meaning". Use of the present tense (rather than forms with will) is mandatory in some subordinate clauses referring to the future, such as "If I feel better next week, ..." and "As soon as they arrive, ...". For more details see the sections on the simple present, present progressive and dependent clauses in the article on English verb forms.
 The going-to future, e.g., "John is going to leave tonight."
 The construction with a finite form of the copula verb be together with the to-infinitive, e.g., "John is to leave tonight". (With the zero copula of newspaper headline style, this becomes simply "John to leave tonight".) For details see am to.
 The construction with to be about to, e.g., "John is about to leave", referring to the expected immediate future. (A number of lexical expressions with similar meaning also exist, such as to be on the point of (doing something).)
 Use of modal verbs with future meaning, to combine the expression of future time with certain modality: "I must do this" (also mun in Northern English dialect); "We should help him"; "I can get out of here"; "We may win"; "You might succeed". The same modal verbs are also often used with present rather than future reference. For details of their meanings and usage, see English modal verbs.

Questions and negatives are formed from all of the above constructions in the regular manner: see Questions and Negation in the English grammar article. The auxiliaries will and shall form the contracted negations won't and shan't (they can also sometimes be contracted when not negated, to  'll).

The various ways of expressing the future carry different meanings, implying not just futurity but also aspect (the way an action or state takes place in time) and/or modality (the attitude of the speaker toward the action or state).  The precise interpretation must be based on the context. In particular there is sometimes a distinction in usage between the will/shall future and the going-to future (although in some contexts they are interchangeable). For more information see the going-to future article.

German
The use of the present tense in future meaning is much more common in German than it is in English. Especially in colloquial German, but also in the written standard language, future tenses are quite rarely used if the future meaning is already evident through context or a temporal adverb or clause. For example:

 In zehn Jahren bin ich Millionär.
 "In ten years, I shall be a millionaire."
 Literally: "In ten years am I millionaire."

German uses an auxiliary for the future: werden (which can also mean "to become.") The main verb after werden is a simple infinitive. The infinitive main verb is placed at the end of the sentence or clause. For example:

 Ich werde dich morgen nach der Arbeit anrufen.
 "I shall call you tomorrow after work."
 Literally: "I will you tomorrow after work call."

A future perfect (in German referred to as Futur II) can be formed by means of replacing the simple infinitive with a past infinitive (past participle + infititive of the relevant auxiliary):

 Ich werde dich angerufen haben
 "I shall have called you."

Some 17th and 18th century grammarians (e.g. J. Kromeyer, J. C. Gottsched, J. B. v. Antesperg) also labeled other future forms, like:
 imperative future: du sollst loben (you shall praise)
 indicative uncertain future (German: ungewiss zukünftige Zeit, Latin: tempus futurum incertum): ich will loben (I want to praise)
 indicative certain future (German: gewiss künftige Zeit, Latin: tempus futurum certum), or indicative future I: ich werde loben (I shall praise)
 indicative conditional future (German: bedingt zukünftige Zeit, Latin: tempus futurum conditionatum), or conjunctive II future: ich würde loben (I would praise)
All these wordings do still exists, but nowadays (usually) only ich werde loben (future I) and sometimes ich würde loben (conjunctive II future) are labeled future forms.

Dutch
Dutch can express the future in three ways:
gaan + infinitive: Ik ga het boek lezen (I'm going to read the book). "Gaan" is a cognate of "to go".
zullen + infinitive: Ik zal het boek lezen (I will/shall read the book). "Zullen" is a cognate of "shall".
 present tense + context or a temporal adverb or clause: Hoe lang blijft hij in Nederland? (How long is he staying in the Netherlands?) Its English-language equivalent uses the continuous or imperfective aspect.
Zullen + infinitive is more similar to shall than to will. It is used to:
express a promise or a proposal
emphasize that something will certainly happen
express that an event is likely going to take place (by explicitly mentioning the probability)
English will and Dutch wil, although cognates, have over the centuries shifted in meaning, such that will is almost identical to shall, whereas Dutch wil means want, as in Ik wil het doen (I want to do it).

Gaan + infinitive can be compared with the English "going to" . It is used:
to express an intended action (but not a promise, proposal, or solemn plan)
to say that an event is going to take place (without emphasizing the certainty or mentioning the probability)

Icelandic and Old Norse
Icelandic descends from Old Norse and  is scarcely changed from it in the written form. Icelandic uses the auxiliaries:

 munu expressing a probable future
 skulu (shall) implying obligation or determination.

It is believed that in Old Norse munu expressed the pure future, skulu (shall) expressed obligation or determination as it still does, and a third auxiliary, vilja ("will"), expressed will or intent.

A common auxiliary expression of the future, which takes the compound infinitive, is:

 ætla expressing intention.

(So Ég ætla að koma;  I will come)

The verb verða (become) is also very commonly used in the meaning "will be", making the lesser used mun vera (will be) have a bit stronger emphasis on the future than the English translation has.

Like many other Germanic languages, the future can also be expressed by simply using the present tense and having in the sentence words that imply future action (e.g. "tomorrow"). Because of this, if it is already evident from the sentence that one is talking about the future, then the verb is almost always in the present tense.

Norwegian

Current standard Norwegian auxiliaries are:

 vil (cognate with "will"; used to indicate desire)
 skal (cognate with "shall"; used to indicate intent)
 kan (cognate with "can"; used to indicate ability)
 kommer/kjem til å (future regardless of intention)
An occasional usage is:

 mon (or in Nynorsk mun.).
etla (Nynorsk)

Danish

In Danish the future is usually unmarked, using the present tense form.  Sometimes the modals  ("want") and  ("must") are used instead to indicate futurity, and sometimes  "become" can have the meaning "will be".  The following distinctions illustrate some of their uses:

 "That will never happen" (a prediction) but  "That shall not happen" (a promise).

 "What will you (do) tonight?";  "I shall visit my parents this weekend";  "Will you go (are you going) home now?".

 "He wants to_be_picked_up";  "He must be_picked_up".   "He will become (get) picked_up (it's already arranged)", but  "He will become (be) picked_up (I promise)".

 "I shall (go) to (a) birthday_party tomorrow".   "That becomes (will be) fun".   "We become (shall be) 15 (there will be fifteen of us)".   "He becomes (will be) 40".

Swedish

Swedish skall strongly implies intention, but with an adverb such as nog "probably" it can avoid the implication of intentionality: Det här skall nog gå bra "This will probably go well".  However, the past tense of skall, skulle, can be used without such an adverb to express predictions in the past:  Pelle sa, att det skulle bli varmt på eftermiddagen "Pelle said that it would be warm in the afternoon."

Pure future, regardless of intention, is usually expressed with kommer att (literally: "comes to"): Det här kommer att gå bra "This will go well", Du kommer att överleva det här "You will survive this".

Generally, future tense is sparsely used in spoken Swedish, with the verb instead being put in present tense and accompanied by a distinct time specification: Jag åker till Spanien på fredag "I travel to Spain on Friday" Då ses vi imorgon. "Then we meet tomorrow"

Latin and Romance 
The future tense forms in Latin varied by conjugation.  Here is a sample of the future tense for the first conjugation verb amare, "to love".

See Latin conjugation for further details. Sound changes in Vulgar Latin made future forms difficult to distinguish from other verb forms (e.g., amabit "he will love" vs. amavit "he loved"), and the Latin simple future forms were gradually replaced by periphrastic structures involving the infinitive and an auxiliary verb, such as debere, venire, velle, or especially habere. All of the modern Romance languages have grammaticalized one of these periphrastic constructions for expressing the future tense; none of them has preserved the original Latin future.

Future tense with habere

While Classical Latin used a set of suffixes to the main verb for the future tense, later Vulgar Latin adopted the use of habere ("to have") with the infinitive, as for example:

petant aut non petant venire habet ("whether they ask or do not ask, it will come")

From this construction, the major Western Romance languages have simple future tense forms that derive from the infinitive followed by a conjugated form of the verb "to have" (Latin habere). As the auxiliary verb lost its modal force (from a verb expressing obligation, desire, or intention, to a simple marker of tense), it also lost syntactic autonomy (becoming an enclitic) and phonological substance (e.g., Latin first singular habeo > ayyo > Old French ai, Modern French ).

Thus the sequence of Latin verbs amare habeo ("I have to love") gave rise to French aimerai, Spanish amaré, etc. "I will love".

Phonetic changes also affected the infinitive in the evolution of this form, so that in the modern languages the future stem is not always identical to the infinitive. Consider the following Spanish examples:
 "go out": infinitive salir → 1st. sing. future saldré in lieu of *saliré
 "know": infinitive saber → 2nd. sing future "sabrás" in lieu of *saberás
 "do": infinitive hacer → 3rd sing. future hará in lieu of *hacerá
 "want": infinitive querer → 3rd pl. future querrán in lieu of *quererán

Romanian

Romanian, although a Romance language, patterns like Balkan languages such as Greek and Serbo-Croatian (cf. Balkan sprachbund) in that it uses reflexes of the verb vrea (to want):
"love": infinitive a iubi → 3rd sing. future va iubi

Romanian also forms a future tense from the subjunctive, with a preceding particle, o, also derived from vrea:
"love": infinitive a iubi → 3rd sing. future o să iubească (lit. (want) that he love)

Portuguese
In Portuguese, there is a simple future conjugation, which is quite similar to the Spanish one (see the table below):

However, there are multiple composed future conjugations such as the following ones:

 vou cantar (Auxiliary go)
 irei cantar (Auxiliary go)
 vim cantar (Auxiliary come)
 venho cantar (Auxiliary come)
 virei cantar (Auxiliary come)
 hei de cantar (Auxiliary exist)
 vou estar cantando (Auxiliaries go + be)
 estarei cantando (Auxiliary be)

Combinations of auxiliary and event verbs such as venho vir and venho ir are not used because the future auxiliaries vim/venho/irei (come) have a residue meaning of coming: vim cantar (I came here to sing), venho cantar (I will sing here), and virei cantar (I will sing here) mean that the speaker will do the described action at the same place where he or she is now. In particular, vou is not only the most used future auxiliary in Portuguese and it is equivalent to will in English. It is also the most used simple future form for the verb ir (to go) meaning will go.

In Portuguese a pronoun may be placed between the root verb and the future tense ending, as in dar-lhe-ei ("I will give it to you"), where the pronoun lhe ("to you") is inserted into the future verb darei ("(I) will give"), between the stem (dar) and the future tense ending (ei). This phenomenon is called mesoclisis.

Sardinian
Sardinian, due to its early breaking off from Proto-Romance, displays different traits in its morphology. Notably, in the future tense, the verb habeo (aere in Sardinian) is instead proclitic, and does not have an individual conjugation on the verb. Instead, aere is conjugated into present tense, and the other verb's infinitive form is used. Thusly,  app'aere, app'appidu and app'aere appidu are aere's future, perfect, and future perfect.

Slavic languages

Slovak 
In the Slovak language, the future tense is formed only with verbs with imperfective grammatical aspect, with the auxiliary verb byť (to be) in future tense:

To this auxiliary verb, the infinitive of the verb to be put into future tense is simply appended:
 robiť (to do, to work): budem robiť (I will work, I will be working)
 hovoriť (to speak, to talk): budeme hovoriť (we will speak/talk, we will be speaking/talking)

Polish 
Polish language uses both suffixes and auxiliary verbs to express the sense of futurity. The only verb which has its own future conjugation is być (to be):

The future tense can be formed in two different ways depending on the aspect of the verb. For imperfective verbs, Polish uses the future tense of być plus the past tense of the verb at the third person or the infinitive. For instance:
 mówić (to say/speak/talk/tell):
-będę mówił (m)/mówiła (f)/ mówiło (n)/mówić (I will say, I will be saying).

-będziesz mówił (m) / mówiła (f) / mówiło (n)/mówić (You will say, you will be saying).

-będzie mówił (m) / mówiła (f) / mówiło (n)/mówić (He/she/it will say, he/she/it will be saying).

-będziemy mówili (mp) / mówiły (nmp) / mówić (We will say, we will be saying).

-będziecie mówili (mp) / mówiły (nmp) / mówić (You will say, you will be saying).

-będą mówili (mp) / mówiły (nmp) / mówić (They will say, they will be saying).

(m) refers to a male, (f) to a female and (n) is neuter, used with inanimate objects. In Plural, (mp) refers to the masculine-personal gender and (nmp) to non-masculine-personal. The form with the infinitive is less common.

Perfective verbs have only the past and future tenses. As they have no present tense, the rules used to form the present tense in imperfective verbs are used to give the sense of futurity to perfective verbs. For instance, the perfective form of mówić is conjugated as follows:
 powiedzieć (to say/speak/talk/tell)

-powiem (I will say, I will be saying)

-powiesz (You will say, you will be saying)

-powie (He/she/it will say, he/she/it will be saying)

-powiemy (We will say, we will be saying)

-powiecie (You will say, you will be saying)

-powiedzą (They will say, they will be saying)

This example follows the rules of the verbs which conjugate according to the model -em, esz. The other models are -am, asz, -ę, esz, -ę, isz and -ę, ysz. Irregular verbs may change their root, but never their desinence (like in the example above where the root powi changes to powiedz in the third person plural).

Celtic languages

Scottish Gaelic

In Scottish Gaelic, the future tense is formed in regular verbs by adding aidh or idh to the end of the root form of the verb (idh is used if the final vowel in the root is i).

Danns. (dance.) -> Dannsaidh mi. (I will dance.)
Cuir. (put.) -> Cuiridh i. (She will put.)

Inserting cha before the root forms the negative.  The initial consonant of the root is lenited where possible, except for d, t or s, which in certain cases is not lenited. Chan is substituted if the root begins with a vowel or an f followed by a vowel, which is also lenited.

Cha téid mi... (I will not go...)
Chan fheuch am peasan sin idir. (That brat will not try at all.)

In the interrogative, an is placed before the root of the verb. If the root begins with b, f, m, or p, am is used instead.

An ith thu sin? (Will you eat that?)
Am pòg thu i? (Will you kiss her?)

As in English, some forms are irregular - mostly common verbs. For example, the root for the word "to see" is faic, but the positive future tense form "will see" is chì.

The copula is bidh (will be), cha bhi (will not be), am bi (interrogative), and nach bi (negative interrogative).

Bidh mi a' tighinn! (I shall be coming!)
Cha bhi e an seo a-màireach. (He will not be here tomorrow.)
Am bi thu air falbh as t-samhradh? (Will you be away this summer?)
Nach bi sibh a' fuireach airson a' bhìdh? (Will not you be staying for the food, sir?)

The linking verb (that will be) is gum bi (positive) or nach bi (negative).

Tha ise ag ràdh gum bi esan a' dol. (She said that he will be going.)
Tha mi an dòchas nach bi iad sgìth. (I hope that they will not be tired.)

Irish

In Irish, the future tense is formed two ways in regular verbs, depending on verb class.  Class I verbs add faidh or fidh to the end of the root form of the verb (fidh is used if the final vowel in the root is e or i).

Glan. (clean.) -> Glanfaidh mé. (I will clean.)
Cuir. (put.) -> Cuirfidh sí. (She will put.)

Class II verbs add óidh or eoidh to the end of the root form of the verb (eoidh is used if the final vowel in the root is e, i, or í).

Eistigh. (listen.) -> Eisteoidh mé. (I will listen.)
Imir. (play.) -> Imreoidh sí. (She will play.)

Both class I and class II verbs have a special form for the 1st person plural:

Glan. (clean.) -> Glanfaimid. (We will clean.)
Cuir. (put.) -> Cuirfimid. (We will put.)
Eistigh. (listen.) -> Eisteoimid. (We will listen.)
Imir. (put.) -> Imreoimid. (We will play.)

The negative is formed by adding ní.  The initial consonant of the root is lenited.

Ní fhreastalóidh mé... (I will not serve...)

In the interrogative, an is placed before the root of the verb, which causes eclipsis.

An iosfaith tú sin? (Will you eat that?)
An bpogfaigh tú í? (Will you kiss her?)

Of the ten listed irregular verbs in Irish, six show irregular future forms:
Abair. (say.) -> Déarfaidh sí. (She will say.) (present deireann)
Beir. (catch/bring.) -> Béarfaidh sí. (She will bring.) (present beireann)
Faigh. (get.) -> Gheobhaidh sí. (She will get.) (present faigheann)
Ith. (eat.) -> Iosfaidh sí. (She will eat.) (present itheann)
Tar. (come.) -> Tiocfaidh sí. (She will come.) (present tagann)
Teigh. (go.) -> Rachaidh sí. (She will go.) (present téann)

One additional irregular verb has an alternate future form:
Feic. (see.) -> Chífidh sí. (She will see.) (regular future feicfidh)

The future of verb tá (be) is beidh (1pl. beimid).  The copula is ("is") is  is (will be), ní (will not be), an (interrogative), and nach (negative interrogative).

The linking verb (that will be) is go mbí (positive) or nach bí (negative).

Duirt sí go mbeidh sé ag dul. (She said that he will be going.)
Tá súil agam nach mbeidh tuirse acu. (I hope that they will not be tired.)

Welsh

In Welsh, most verbal functions are expressed using constructions with bod (to be).  The future may be expressed in the same way using the future tense of bod.

Fe fydda i yn... (I will...)Fe fyddi di yn... (thou wilt...)Fe fydd e yn... (he will...) etc.

(The affirmative marker "fe" has no real translation in English and can easily be left out or replaced with 'mi' in North Wales. Neither word should be confused with subject pronouns which follow the verb in Welsh).

More commonly Welsh uses a construction with "Mynd" (to go)

"Rwy'n mynd i weld y ffilm yfory" (I'm going to see the film tomorrow)

Futurity can also be expressed by using words that imply future actionDwi'n mynd yna heddiw: I am going there today.

The simple future, which uses verb suffixes conjugated with the verb, is used to express determination of action or to emphasise confidence in outcome.  As in the future of bod, the affirmative marker is fe.

Semitic languages
Hebrew
Biblical Hebrew has a distinction between past and future tenses which is similar in form to those used in other Semitic languages such as Arabic and Aramaic. Gesenius refers to the past and future verb forms as Perfect and Imperfect, respectively, separating completed action from uncompleted action. However, the usage of verbs in these forms does not always have the same temporal meaning as in Indo-European languages, mainly due to the common use of a construct of inverting the time reference with a prefix "Waw consecutive" (ו' ההיפוך). With this construct,  the Perfect-consecutive refers to the future  and the Imperfect-consecutive refers to the past.

Usage of the imperfect to discuss future events is somewhat uncommon in Biblical Hebrew, as the Bible mainly discusses past events. It can be found in quoted speech, such as in the words of Moses (imperfect verbs stressed):

The Perfect-consecutive is commonly found in prophetic text, describing an unspecified future, as in the Book of Isaiah:

Modern Hebrew always employs the imperfect as the future tense (and the perfect as the past tense). The usage of "Waw consecutive" has practically disappeared, except for quotes from the Bible and Poetic language.

Arabic

To form future tense in Arabic the prefix (سـ) "sa" is added to the present tense verb, or (سوف) "sawfa".

For example, consider the sentence:
I eat apples > "آكلُ تفاحاً" "Akulu tuffahan"

To express the future we have two ways:
I will eat apples > "سـآكلُ تفاحاً"  "Saakulu tuffahan"
or:
I will eat apples >  "سوف آكلُ تفاحاً"  "Sawfa akulu tuffahan"

The first is written as part of the verb, whereas the latter is written as a Clitic to indicate the future but preceding the verb.

In Classical Arabic the latter indicates an individual future action that usually takes place further in the future than the first mentioned form, which is usually used with verbs that relate to other actions, and mostly referring to rather near future actions.
However, in Modern Standard Arabic (MSA) the distinction is minimal.

Moreover, the indication of the future tense in dialectal Arabic is quite varied from one dialect to the next.
Generally speaking, the words meaning "want to" (بدي / أريد أن), "go to" (أروح), "intend to"(ناوي /نويت), and many others are used daily to indicate future actions.
In Moroccan Arabic, the word "Ghad" (غاد) is used to indicate future, which literally means "there" (or there is to happen), that is in some way similar to the English formation "there I go.."

Mandarin Chinese
Mandarin Chinese has no grammatical tense, instead indicating time of action from the context or using adverbs.  However, the auxiliary verb 會 /  - huì / ㄏㄨㄟˋ, a modal meaning "can", "know how", can alternatively indicate futurity.  For lexical futurity, the word  yào, which can serve as a verb meaning "to want", can also serve as an adverb meaning "immediately": For example,  wǒ yào xǐzǎo can mean either "I want to bathe" or "I am about to bathe".  即 jí、將 jiāng serve a similar function as tense-marking adverbs.

Creoles
Creoles are languages with a vocabulary heavily based on a superstrate language but a grammar based on substrate languages and/or universal language tendencies.  Some Creoles model a future tense/irrealis mood marker on "go" from the superstrate (analogous to English "am going to").  In many creoles the future can be indicated with the progressive aspect, analogous to the English "I'm seeing him tomorrow."  In general creoles tend to put less emphasis on marking tense than on marking aspect.  When any of tense, aspect, and modality are specified, they are typically indicated with invariant pre-verbal markers in the sequence anterior relative tense (prior to the time focused on), irrealis mode (conditional or future), imperfective aspect.

Jamaican English Creole

The future marker in Jamaican Creole is /de go/ or /a go/: /de go hapm/ "is going to happen", /mi a go ɹon/ "I am going to run".

Belizean Creole English

In Belizean Creole, the future tense is indicated by a mandatory invariant pre-verbal particle /(w)a(n)/, /gwein/, or /gouɲ/.

Gullah

In Gullah the future is indicated by the pre-verbal marker gwine:  Uh gwine he'p dem "I'm going to help them".

Hawaiian Creole English

In Hawaiian Creole, the pre-verbal future marker is gon:  Ai gon bai wan pikap "I'm going to buy a pickup".

Haitian Creole

Haitian Creole, based on a French superstrate, interchangeably uses pral or va (from French 3rd person singular va "goes") pre-verbally to indicate the future:  Mwen va fini lit. "I go finish"; Li pral vini jodi a'' "He will come today".
