THE ROLE OF VOCABULARY IN DEVELOPING COMMUNICATIVE COMPETENCE

Vocabulary is one of the most essential components of language proficiency and communicative competence. Without sufficient vocabulary knowledge, learners cannot express ideas, understand messages, or participate meaningfully in communication, regardless of how well they know grammatical structures. This article examines the central role of vocabulary in developing communicative competence in English language learning. It explores theoretical perspectives, the relationship between vocabulary and language skills, psychological and cognitive aspects of vocabulary acquisition, and pedagogical strategies for effective vocabulary instruction. The study highlights how vocabulary enables learners to perform communicative functions, achieve pragmatic competence, interpret meanings in various contexts, and participate in academic, social, and professional communication.
