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

Аннотация

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. Keywords and phrases: terminology theory, theoretical foundations, functional linguistics, trade terminology, a lexical unit, a term, domain-specific vocabulary, general vocabulary, trade discourse, loanwords and borrowings. In the contemporary globalized world, where economic interconnectedness continues to expand, the role of language in trade and commerce has grown significantly. Clear, accurate, and systematized terminology is essential for effective communication in international trade. Among the most fundamental components of this system are lexical units, which serve as the foundational elements of specialized communication within economic discourse. In this article, I examine the theoretical foundations of trade-related lexical units and terms in English and Uzbek by exploring how domain-specific vocabulary is formed, functions, and evolves within the linguistic frameworks of both languages. This discussion is particularly important within the broader context of my research, which aims to uncover the functional and translational features of trade lexicon. A comprehensive understanding of the underlying theoretical concepts is essential before addressing deeper questions of linguistic function or equivalence in translation. Therefore, I approach this topic through a 105 ACADEMIC RESEARCH IN MODERN SCIENCE International scientific-online conference comparative linguistic lens, grounded in modern theories such as functionalism, cognitive linguistics, and terminology theory. I also consider the contributions of Uzbek linguists, including H. Dadaboyev, D. Nabijonova1, and O. Ahmedov2, alongside internationally recognized scholars like J. Sager, C. Fillmore3, and M. Baker4. To begin with, the concept of a lexical unit must be clearly understood. As defined by Cruse, a lexical unit is not merely a word, but a unit of meaning that may be realized as a single word or a multi-word expression.5 In linguistic terms, it represents an abstract entry in the mental lexicon, encapsulating both form and meaning. In the context of trade, such units include expressions like “import”, “trade balance” or their Uzbek counterparts, such as “eksport” and “savdo balansi”. Uzbek linguist H. Dadaboyev emphasizes that lexical units in Uzbek function both as nominative and communicative elements, organized through syntagmatic and paradigmatic relations in speech.6 Building on this, a distinction must be made between general vocabulary and terms. A term is a lexical unit that acquires a specific, standardized meaning within a particular domain of knowledge. As Sager notes, a term represents a concept defined and stabilized by experts in the relevant field. Unlike general vocabulary, which is often polysemous and fluid, terms aim for monosemy, precision, and contextual restriction.7 For example, the English word “depression” might refer to a psychological state in general discourse but denotes a prolonged economic downturn in financial contexts. The Uzbek equivalent “rivojlanish” similarly shifts meaning depending on context, where “iqtisodiy rivojlanish” clearly anchors the term in the trade domain. Understanding the difference between general and domain-specific vocabulary is essential for the categorization of trade-related lexicon. Domain- specific vocabulary encompasses lexical items used predominantly within a specific field such as economics or trade. These words are characterized by 1 Nabijonova D.
