The communicative approach in language teaching derives from the theory that language is communication. The goal of language teaching is to develop what Hymes calls “communicative competence.” Hymes used it to compare Chomsky's theory of power to that of a linguistic language. According to Chomsky, linguistic theory deals with an ideal speaker-listener in a totally homogeneous linguistic environment, this person is not influenced by grammatical ideals such as forgetfulness, inhibitors, deviations of interest and attention and errors in questioning one's linguistic knowledge . real productivity.

Hymes argues that this type of linguistic theoretical view is far from natural and that linguistic theory should be seen as part of a more general theory that combines communication and culture. Hymes' communicative competence was a definition of what a hypothetical speaker would need to know to have the ability to communicate in a speaking environment. According to Hymes, a person acquires a communicative competence which: is something formally possible; can be achieved with existing means of implementation; is appropriate in terms of the context in which something is used and; it is something actually done, really implemented in terms of concepts, both the knowledge and the ability to use the language. This theory, based on what language contains, offers a much more comprehensive view than Chomsky's ability to deal with abstract grammatical knowledge at the forefront. Another linguistic interest in communicative language teaching is the idea of ​​Halliday's functional use of language use being theorized. “Linguistics is linked to the use of words or the definition of texts, since all the functions of the language and therefore all the components of meaning are significant only through the language used”. In a series of influential books and articles, Halliday developed a theory of strong language functions that support Hymes' view of communicative power for many writers on teaching communicative language. Hymes identified seven basic functions of language for children learning their first language: vehicle type function: use to reach something tangible; normative function: using language to control the behavior of others; function based on mutual communication: using language to initiate mutual communication. with others; personal function: using language to express personal feelings and meanings; developmental function: using for language learning and exploration; creation-based function: using language to create a world based on imagination; representative: use for communicating information language.
