This article examines clichés as fixed speech units from the perspective of syntagmatic analysis. Clichés are described as ready-made speech formulas that facilitate communication while also conveying semantic, social, and situational information. The author distinguishes between two main types of clichés nominative and communicative and analyzes their structural and functional characteristics. Nominative clichés perform a naming function and operate in a sentence as a single nominative component while preserving their internal structural stability. Communicative clichés, in contrast, function as ready-made speech formulas capable of expressing a complete speech act and serving as independent syntactic units. The paper also discusses the relationship between syntagmatic and paradigmatic relations in language, drawing on Ferdinand de Saussure’s ideas.
