Abstract. This article explores the linguistic features of complex constructions in the English language with a focus on their structural, semantic, and functional characteristics. Complex constructions play a crucial role in expressing logical relations, abstract thinking, and stylistic variation in both spoken and written discourse. The study examines how such constructions contribute to coherence, clarity, and communicative effectiveness in English. Particular attention is given to the interaction between syntax and meaning, as well as to the role of complex constructions in academic and professional communication. The research emphasizes that understanding these linguistic patterns is essential for advanced language competence and effective language teaching.
