THE ROLE AND SIGNIFICANCE OF AI-ASSISTED LEXICAL EXPANSION IN ELF EDUCATION

Abstract

  This study examines the role and significance of AI-assisted lexical expansion in English as a Lingua Franca (ELF) education. As ELF communication involves speakers from diverse linguistic and cultural backgrounds, developing a broad, flexible, and context-sensitive vocabulary is essential for effective interaction. The paper explores how artificial intelligence–based tools—such as adaptive learning systems, intelligent tutoring platforms, and language models—support lexical expansion by providing personalized input, real-time feedback, and usage-based vocabulary practice. Special attention is given to the ways AI enhances learners’ awareness of variation, pragmatics, and meaning negotiation in ELF contexts. The study highlights the pedagogical advantages of AI-assisted lexical learning, including increased learner autonomy, improved retention, and exposure to authentic, diverse language use. At the same time, potential challenges such as overreliance on technology, data bias, and the need for teacher mediation are discussed. The findings suggest that when integrated thoughtfully, AI-assisted lexical expansion can play a significant role in improving communicative competence in ELF-oriented education.
