LinguisticsLinguistics is the scientific study of language. The modern-day scientific study of linguistics takes all aspects of language into account — i.e., the cognitive, the social, the cultural, the psychological, the environmental, the biological, the literary, the grammatical, the paleographical, and the structural. Linguistics is based on a theoretical as well as descriptive study of language, and is also interlinked with the applied fields of language studies and language learning, which entails the study of specific languages.
Interactional linguisticsInteractional linguistics (IL) is an interdisciplinary approach to grammar and interaction in the field of linguistics, that applies the methods of Conversation Analysis to the study of linguistic structures, including syntax, phonetics, morphology, and so on. Interactional linguistics is based on the principle that linguistic structures and uses are formed through interaction and it aims at understanding how languages are shaped through interaction. The approach focuses on temporality, activity implication and embodiment in interaction.
Langue and paroleLangue and parole is a theoretical linguistic dichotomy distinguished by Ferdinand de Saussure in his Course in General Linguistics. The French term langue ('[an individual] language') encompasses the abstract, systematic rules and conventions of a signifying system; it is independent of, and pre-exists, the individual user. It involves the principles of language, without which no meaningful utterance, or parole, would be possible.
Speech communityA speech community is a group of people who share a set of linguistic norms and expectations regarding the use of language. It is a concept mostly associated with sociolinguistics and anthropological linguistics. Exactly how to define speech community is debated in the literature. Definitions of speech community tend to involve varying degrees of emphasis on the following: Shared community membership Shared linguistic communication A typical speech community can be a small town, but sociolinguists such as William Labov claim that a large metropolitan area, for example New York City, can also be considered one single speech community.
GrammaticalityIn linguistics, grammaticality is determined by the conformity to language usage as derived by the grammar of a particular speech variety. The notion of grammaticality rose alongside the theory of generative grammar, the goal of which is to formulate rules that define well-formed, grammatical, sentences. These rules of grammaticality also provide explanations of ill-formed, ungrammatical sentences.
Functional linguisticsFunctional linguistics is an approach to the study of language characterized by taking systematically into account the speaker's and the hearer's side, and the communicative needs of the speaker and of the given language community. Linguistic functionalism spawned in the 1920s to 1930s from Ferdinand de Saussure's systematic structuralist approach to language (1916). Functionalism sees functionality of language and its elements to be the key to understanding linguistic processes and structures.
Language deathIn linguistics, language death occurs when a language loses its last native speaker. By extension, language extinction is when the language is no longer known, including by second-language speakers, when it becomes known as an extinct language. A related term is linguicide, the death of a language from natural or political causes, and, rarely, glottophagy, the absorption or replacement of a minor language by a major language.
Second-language acquisitionSecond-language acquisition (SLA), sometimes called second-language learning — otherwise referred to as L2 (language 2) acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education.
Language acquisitionLanguage acquisition is the process by which humans acquire the capacity to perceive and comprehend language (in other words, gain the ability to be aware of language and to understand it), as well as to produce and use words and sentences to communicate. Language acquisition involves structures, rules, and representation. The capacity to use language successfully requires one to acquire a range of tools including phonology, morphology, syntax, semantics, and an extensive vocabulary.
Generative grammarGenerative grammar, or generativism ˈdʒɛnərətɪvɪzəm, is a linguistic theory that regards linguistics as the study of a hypothesised innate grammatical structure. It is a biological or biologistic modification of earlier structuralist theories of linguistics, deriving ultimately from glossematics. Generative grammar considers grammar as a system of rules that generates exactly those combinations of words that form grammatical sentences in a given language.
