In linguistics and cognitive science, cognitive linguistics refers to a linguistic school of thought who believes that the creation, learning and language use are best explained by reference to human cognition in general.
Cognitive linguistics is characterized by its adherence to three basic postulates. First, it denies that there is an autonomous language faculty in the mind, then it considers the grammar in terms of conceptualization, and finally, it says that knowledge of language comes from the use of the language.
Cognitive linguists reject the idea that the human mind possesses any single autonomous module and to language learning. This attitude contrasts with work in the field of generative grammar. Although cognitive linguists do not deny that part of the human language ability is innate, they reject the idea that it is separated from the rest of cognition. Thus, they argue that knowledge of linguistic phenomena - ie the phonemes, morphemes, and syntax - is essentially conceptual in nature. In addition, they argue that the storage and access mode are not fundamentally different for linguistic data and other knowledge data, and that the use of language for understanding use cognitive abilities similar to those esxisting for other non-linguistic tasks.
