This document discusses different views on the concept of communicative competence proposed by Ferdinand de Saussure, Noam Chomsky, and Dell Hymes. De Saussure viewed language as a social norm and speaking acts as individual manifestations of that norm. Chomsky defined linguistic competence as the language someone knows and performance as speech acts. Hymes proposed communicative competence as the ability to use language appropriately based on what is grammatically possible, feasible, and appropriate for the context. The views represent a sociological, rationalistic, and pragmatic distinction respectively. Later work by Canale and Swain expanded on Hymes' theory to include grammatical, sociolinguistic, and strategic competences.
