The concept of communicative competence, as developed in linguistics, originated in response to perceived inadequacy of the notion of linguistic competence. That is, communicative competence encompasses a language user's grammatical knowledge of syntax, morphology, phonology and the like, but reconceives this knowledge as a functional, social understanding of how and when to use utterances appropriately.
Communicative language teaching is a pedagogical application of communicative competence.[1]
The understanding of communicative competence has been influenced by the field of pragmatics and the philosophy of language, including work on speech acts.[2]
