Abstract: This article provides a comprehensive examination of the dynamic interplay between lexical exchange—the process of borrowing and integrating words across languages—and semantic extension—the process by which words acquire new or shifted meanings. Drawing on foundational theories in historical linguistics, lexical semantics, and language contact studies, as well as contemporary corpus-based and computational methodologies, this review synthesizes current understanding of these phenomena. It delineates core concepts, explores the cognitive and sociolinguistic mechanisms driving semantic change, and analyzes how contact-induced lexical innovation often serves as a catalyst for semantic extension. The paper surveys diverse methodological approaches, from traditional philological analysis to modern vector space models, for detecting and quantifying semantic shift. Illustrated with cross-linguistic case studies, the analysis underscores that lexical exchange is not merely a process of addition but a complex driver of systemic reorganization within the lexicon. The theoretical implications for semantic typology, contact linguistics, and computational linguistics are discussed, concluding with directions for future research that integrates qualitative and quantitative paradigms to further unravel the intricacies of lexical evolution.
Key words: lexical borrowing, semantic change, semantic extension, language contact, metaphor, metonymy, computational linguistics, historical linguistics, lexicology.
