Linguistic competence is efined as a speaker-hearer’s ability to speak and understand language in a grammatically-correct manner . It is one of the two elements in Chomsky's performance/competence distinction. Linguistic competence is an area of study in the field of intercultural communication founded by the linguist Noam Chomsky. Linguistic competence is the use of grammatical rules of a language, whereas communicative competence is the use of social language rules. This broader knowledge to communicate successfully within the norms of a culture’s language was introduced by the linguist Dell Hymes. Dell Hymes expanded on Noam Chomsky’s view of linguistic competence by considering the social factors of the culture’s language.
