The earliest activities in the documentation and description of language have been attributed to the 4th century BCE Indian grammarian Panini , who wrote a formal description of the Sanskrit language in his .. language. language. documentation. language documentation. description of language. descriptive linguistics.

The study of language meaning , on the other hand , deals with how languages encode relations between entities , properties , and other aspects of the world to convey , process , and assign meaning , as well as manage and resolve ambiguity .. language. language. meaning.

While the study of semantics typically concerns itself with truth conditions , pragmatics deals with how situational context influences the production of meaning .. meaning.

Grammar is a system of rules which governs the production and use of utterances in a given language .. language. language. Grammar. Grammar. utterances. utterances. These rules apply to sound as well as meaning , and include componential sub-sets of rules , such as those pertaining to phonology -LRB- the organisation of phonetic sound systems -RRB- , morphology -LRB- the formation and composition of words -RRB- , and syntax -LRB- the formation and composition of phrases and sentences -RRB- .. meaning.

Modern theories that deal with the principles of grammar are largely based within Noam Chomsky 's ideological school of generative linguistics .. Noam Chomsky.

In the early 20th century , Ferdinand de Saussure distinguished between the notions of langue and parole in his formulation of structural linguistics .. Ferdinand de Saussure. Ferdinand de Saussure. structural linguistics. structural linguistics. langue. language. According to him , parole is the specific utterance of speech , whereas langue refers to an abstract phenomenon that theoretically defines the principles and system of rules that govern a language .. language. language. langue. language. This distinction resembles the one made by Noam Chomsky between competence and performance in his theory of transformative or generative grammar .. Noam Chomsky. Noam Chomsky. competence. linguistic competence. transformative. generative grammar. generative grammar. universal grammar. According to Chomsky , competence is an individual 's innate capacity and potential for language -LRB- like in Saussure 's langue -RRB- , while performance is the specific way in which it is used by individuals , groups , and communities -LRB- i.e. , parole , in Saussurean terms -RRB- .. language. language. langue. language. competence. linguistic competence. The study of parole -LRB- which manifests through cultural discourses and dialects -RRB- is the domain of sociolinguistics , the sub-discipline that comprises the study of a complex system of linguistic facets within a certain speech community -LRB- governed by its own set of grammatical rules and laws -RRB- .. dialects. dialects. sociolinguistics. sociolinguistics. speech community. speech community. Discourse analysis further examines the structure of texts and conversations emerging out of a speech community 's usage of language .. language. language. speech community. speech community.

This is done through the collection of linguistic data , or through the formal discipline of corpus linguistics , which takes naturally occurring texts and studies the variation of grammatical and other features based on such corpora -LRB- or corpus data -RRB- .. corpus linguistics. corpus linguistics.

The formal study of language also led to the growth of fields like psycholinguistics , which explores the representation and function of language in the mind ; neurolinguistics , which studies language processing in the brain ; biolinguistics , which studies the biology and evolution of language ; and language acquisition , which investigates how children and adults acquire the knowledge of one or more languages .. language. language. psycholinguistics. psycholinguistics. neurolinguistics. neurolinguistics. biolinguistics. biolinguistics. language acquisition. language acquisition.

Research on language through the sub-branches of historical and evolutionary linguistics also focus on how languages change and grow , particularly over an extended period of time .. language. language. historical. historical linguistics. evolutionary linguistics. evolutionary linguistics. period of time. diachronic linguistics.
