The following outline is provided as an overview and topical guide to linguistics: Linguistics is the scientific study of language. Someone who engages in this study is called a linguist. Linguistics has two subdivisions, general and applied.
Branches of linguistics
Subfields of linguistics General linguistics Phonetics – the study of the speech faculty Phonology – the usage of vocalized sounds and systems of sounds to form language Morphology – the property of sound and meaning dynamics in language Syntax – the property of grammar that governs sentence structure Semantics – the study of meaning as encoded in grammar Pragmatics – the study of how context contributes to meaning Graphemics – the study of writing systems Graphetics – the study of writing shapes as assigned to sounds or ideas Theoretical linguistics – the study of language as an abstract object Generative linguistics – an approach which seeks to ground grammar in a specialized language module Formalism (linguistics) – the theory of language as a formal system with mathematical-logical rules and a formal grammar Functional linguistics – language as used and coming from use Quantitative linguistics – the study of quantitative language laws and corresponding general theories Formal semantics – the study of semantics through formal logic-based models Descriptive linguistics – describing how a particular language is used Anthropological linguistics – the place of language in its wider social and cultural context, and its role in making and maintaining cultural practices and societal structures Historical linguistics – the study of historical language change over time Comparative linguistics – comparing languages to find similarities and historical connections Etymology – the study of word histories and origins Lexicology – the study of vocabularies and the structural relationships between many different words Sociolinguistics – the study of society's effects on language Discourse analysis – analysis of language use in texts (spoken, written, or signed) Linguistic typology – comparative study of the similarities and differences between language structures in the world's languages. Applied linguistics – finding solutions to real-life problems related to language Computational linguistics – the use of computation applied to language databasing, analysis, translation, and synthesis Forensic linguistics – language science applied to the processes of law and justice Internet linguistics – the study of language usage on the Internet Language assessment – assessing first or second language faculty in individuals Language documentation – comprehensive description of the grammar and use practices of languages of a particular group Language revitalization – an attempt to halt or reverse the decline of a language or to revive an extinct one Language education – teaching specific language and language science Linguistic anthropology – the study of how language influences social life Psycholinguistics – the study of the psychological and neurobiological factors that enable humans to acquire, use, comprehend and produce language Cognitive linguistics – an approach which seeks to ground grammar in general cognition Language acquisition – the study of how children and adults acquire language knowledge and ability Language development – the study of early language formation Second-language acquisition – the study of how a second language is learned
Subfields, by linguistic structures studied Sub-fields of structure-focused linguistics include:
Phonetics – the study of the physical properties of speech (or signed) production and perception Phonology – the study of sounds (or signs) as discrete, abstract elements in the speaker's mind that distinguish meaning Morphology – the study of internal structures of words and how they can be modified Syntax – study of how words combine to form grammatical sentences Semantics – the study of the meaning of words (lexical semantics) and fixed word combinations (phraseology), and how these compose to form the meanings of sentences Pragmatics – the study of how utterances are used in communicative acts – and the role played by context and nonlinguistic knowledge in the transmission of meaning
Subfields, by nonlinguistic factors studied Applied linguistics – the study of language-related issues applied in everyday life, notably language policies, planning, and education. (Constructed language fits under Applied linguistics.) Biolinguistics – the study of the biological and evolutionary components of human language Clinical linguistics – application of linguistic theory to the field of Speech-Language Pathology Computational linguistics – the study of linguistic issues in a way that is 'computationally responsible', i.e., taking careful note of computational consideration of algorithmic specification and computational complexity, so that the linguistic theories devised can be shown to exhibit certain desirable computational properties implementations Developmental linguistics – the study of the development of linguistic ability in individuals, particularly the acquisition of language in childhood Historical linguistics, or diachronic linguistics – the study of language change over time. Includes archaeolinguistics (or archaeological linguistics), and the dubious field of paleolinguistics. Language geography – the study of the geographical distribution of languages and linguistic features Neurolinguistics – the study of the structures in the human brain that underlie grammar and communication Psycholinguistics – the study of the cognitive processes and representations underlying language use Sociolinguistics – the study of variation in language and its relationship with social factors Stylistics – the study of linguistic factors that place a discourse in context
