Lexical Ambiguity and Meaning Negotiation in Academic Discourse

Abstract

Lexical ambiguity is an inherent feature of natural language and plays a crucial role in shaping meaning in academic discourse, where precision and clarity are paramount. This study investigates how lexical ambiguity emerges and is negotiated in academic communication through contextual, pragmatic, and interactional mechanisms. Drawing on theories from lexical semantics and pragmatics, particularly sense relations, contextual disambiguation, and meaning negotiation, the research examines how academic writers and speakers manage polysemous and homonymous lexical items across disciplinary texts. Using a qualitative–quantitative mixed-methods approach, the study analyzes a corpus of research articles, conference presentations, and classroom discussions from selected academic disciplines. Instances of lexical ambiguity are identified and examined in relation to co-text, disciplinary conventions, and pragmatic cues such as hedging, reformulation, and metadiscourse. The findings reveal that rather than obstructing communication, lexical ambiguity often functions as a strategic resource that facilitates conceptual flexibility and interdisciplinary dialogue. Meaning negotiation occurs through explicit clarification, contextual alignment, and shared disciplinary knowledge, highlighting the dynamic interplay between semantic indeterminacy and pragmatic interpretation. The study contributes to ongoing debates at the semantics–pragmatics interface and offers pedagogical implications for academic literacy and EFL instruction by emphasizing the need to develop learners’ awareness of ambiguity management in academic contexts.
