THE ROLE OF PARENTHETICAL CLAUSES IN POLYCOMPONENT COMPOSITE SENTENCES

This article examines the role of parenthetical clauses (PCs) in the structure of polycomponential composite sentences within English discourse, focusing on their structural, semantic, and pragmatic functions. Parenthetical constructions are analyzed as integral elements that contribute not only to syntactic complexity but also to discourse organization and speaker subjectivity. The study is based on examples drawn from contemporary English literary texts, where parenthetical clauses frequently occur in interaction with multiple predicative units. The findings reveal that PCs function as discourse markers, modal operators, and expressive devices that enhance textual cohesion and communicative effectiveness. They serve to indicate information sources, express emotional and evaluative attitudes, organize discourse flow, and establish interaction between narrator and reader. The study also highlights the typological relevance of parenthetical constructions across English, Uzbek, and Russian, demonstrating their role as universal mechanisms for realizing subjective meaning in language.
