THE ROLE OF LINGUISTIC THEORIES IN SHAPING TRADE LEXICON IN ENGLISH AND UZBEK

This article examines the theoretical foundations of trade-related lexical units in English and Uzbek, forming the conceptual basis for broader research on their functional and translational features. Through a comparative linguistic approach, the study defines key concepts such as lexical units, terms, and domain-specific vocabulary, while also exploring their structural and semantic characteristics within trade discourse. Drawing upon terminology theory, functional linguistics, and cognitive metaphor theory, the research categorizes trade lexicon into core terms, metaphorical expressions, borrowed elements, and collocational units. Contributions by both Western and Uzbek linguists are critically assessed to highlight cross-linguistic patterns and divergences in terminology development. The findings underscore the importance of a scientifically grounded understanding of specialized vocabulary in facilitating effective communication and accurate translation in economic contexts.
