Abstract
The article examines the cumulative functions of cosmonymic concepts in Kazakh and Anglo-Celtic cultural contexts. Cosmonyms are viewed not merely as astronomical names but as semiotic repositories that preserve collective experience, worldview patterns, and value orientations of an ethnic community. The study aims to analyze the cultural and cognitive functions of the conceptual pairs Temirqazyq Polaris, Jetiqaraqshy Big Dipper, Ürker Pleiades, and Qus joly Milky Way. The research employs comparative linguocultural analysis, mythopoetic interpretation, and semantic examination. The findings demonstrate that in the Kazakh worldview, cosmic names regulate ecological cycles, seasonal rhythms, and ethical behavioral norms, forming a coherent cultural model linking nature and human life. In the Anglo-Celtic tradition, these cosmonyms primarily retain symbolic, religious, and poetic functions rather than practical ecological relevance. The study contributes to ethnolinguistics and cultural semiotics by clarifying how linguistic units encode long-term cultural memory and worldview continuity.
