The article analyzes the national and cultural aspects of kinship terminology from a linguocultural and axiological perspective. Kinship terms are interpreted not only as lexical units denoting biological relations but also as cultural phenomena encoding moral and aesthetic values, social norms, and traditions within society. The study highlights the referential and performative functions of kinship terms, showing how they reinforce social hierarchy, age and gender norms, and transmit religious and spiritual values through language. As carriers of cultural memory, kinship terms play a strategic role in ensuring both individual and collective identity, regulating social relations, and strengthening intergenerational continuity. Their universal and culture-specific features are revealed through comparative-typological analysis, which establishes kinship terminology as an important methodological framework for studying the interaction between language and society.
