LEXICAL REPETITION AS A MEANS OF TEXTUAL COHESION IN RUSSIAN AND UZBEK

The article examines lexical repetition as a mechanism of intersentential and thematic cohesion in Russian and Uzbek texts. The study distinguishes exact word-form repetition, repetition of the same lexeme in grammatically different forms, and recurrent nomination within a lexical chain. The theoretical framework draws on research on cohesion, lexical patterning and text organization, while the contrastive analysis focuses on the different morphological profiles of Russian and Uzbek. It is argued that the cohesive force of repetition cannot be reduced to graphic identity: in Russian, the same lexical base may be realized through fusional inflection, whereas in Uzbek the lexical root is normally more transparent within an agglutinative sequence of affixes. On the functional level, however, both languages use repetition to preserve referential identity, maintain a microtopic, connect theme and rheme across sentence boundaries, and prepare the transition from lexical identity to pronominal, synonymous or semantically related nomination. The article proposes a functional model of lexical repetition based on four parameters: degree of lexical identity, morphological variation, change of syntactic role, and discourse function. Particular attention is paid to chain linkage, genre differences and the distinction between constructive repetition and redundant tautology. The analysis shows that repetition is most productive when it does identifiable textual work: it keeps the referent active, stabilizes terminology, marks thematic continuity or creates an intentional semantic accent. The contrastive perspective demonstrates that Russian and Uzbek differ primarily in the formal visibility of repeated lexemes, while the core cohesive functions are largely comparable.
