This article examines the semantic characteristics of certain lexical units found in Uzbek dialects, analysing their occurrence across various linguistic sources and the processes of semantic expansion and narrowing. The main objective of the study is to determine the semantic dynamics of clothing-related terms, assess their semantic potential within the literary language, and explore the sociolinguistic factors influencing this process. The research employs descriptive, comparative, and statistical-linguistic methods to carry out a lexical-semantic analysis of clothing names. The semantic fields, synonymic chains, and historical patterns of usage of the examined words have been identified. This process is closely linked to communicative necessity and normative language policy. In conclusion, the systematic study of dialectal lexical units contributes to a deeper understanding of the internal developmental mechanisms of the Uzbek language, enriches natural word-formation processes, and broadens lexical norms. The results of this study have practical relevance for lexicography, translation studies, and language education.
