Abstract. This paper explores the lingua-cultural aspects of phraseological units containing names of body parts. Phraseological units are an essential part of any language, reflecting not only linguistic creativity but also the cultural values and worldview of the speakers. Body parts as semantic components in idiomatic expressions carry rich metaphorical meanings that vary across cultures. By analyzing these units in different languages, the study reveals both universal cognitive patterns and culture-specific features. Understanding these linguistic and cultural nuances is crucial for effective cross-cultural communication, translation, and language teaching. The research highlights the importance of phraseological units as cultural markers and cognitive tools that deepen our understanding of language as a reflection of human experience.
