Communicative competence involves more than just grammar and vocabulary knowledge. It has four components: linguistic competence, sociolinguistic competence, discourse competence, and strategic competence. Linguistic competence involves word and sentence formation skills. Sociolinguistic competence involves appropriate language use for settings, topics, and expressing attitudes. Discourse competence involves combining language into conversations and texts. Strategic competence involves understanding misunderstandings and expressing ideas without perfect knowledge. Models of communicative competence include linguistic, sociolinguistic, and strategic dimensions.
