Abstract. By examining syntactic structures, pragmatic functions, and sociolinguistic contexts, the study reveals that interrogatives are not merely grammatical constructs but are culturally encoded mechanisms that convey politeness, authority, curiosity, or social hierarchy. Through comparative analysis of interrogative forms in various languages and their usage in specific speech situations, this research highlights the role of interrogative structures in expressing cultural values and shaping communicative behavior. The findings underscore the interrelation between language, thought, and culture, suggesting that interrogative sentences serve as windows into the worldview and interactional norms of a speech community.
