Abstract. This review presents and analyzes Radoslav Tsonev’s monograph Bulgarian Colloquial Syntax, which examines understudied aspects of syntactic organization in spoken Bulgarian. The discussion focuses on syntactic constructions, word order, the use and functional competition of coordinating and subordinating conjunctions, as well as asyndetic constructions. Particular attention is paid to repetitive and elliptical constructions, the functional polysemy of conjunctions, and the interaction between paratactic and hypotactic relations. The review highlights the importance of comparisons with Bulgarian dialects, Old Bulgarian, and other Slavic languages for understanding historical continuity in syntactic phenomena. The monograph is highly evaluated for its scholarly contribution, while the review raises broader questions concerning the persistence and historical development of syntactic features in colloquial Bulgarian.
Keywords: Bulgarian language, colloquial syntax, word order, syntactic constructions, conjunctions, parataxis, hypotaxis
