This article examines the use of nostalgic lexical units in fiction and analyzes their functional-semantic, axiological, and psycholinguistic characteristics. Nostalgic units are linguistic means that evoke warm and joyful memories of the past in human consciousness, thereby enhancing the emotional impact of a literary text. Using Utkir Hoshimov’s Dunyoning ishlari as the primary material, the study explores the functions of nostalgic lexical units in the text and their artistic-aesthetic load. The article also considers issues arising in translation, including cultural differences, and offers an analysis based on a linguocultural approach.
