This paper considers the linguistic analysis of kinship terms on the example of English and Uzbek languages. This paper discusses various approaches to the study of these terms, their classification and criteria for their selection. Kinship determines social relations, determines the place of a person in society and corrects his behavior. Moreover, the terms of kinship and properties reflect the originality of the language, the specifics of the national path, and therefore characterize the national mentality. The terms of kinship belong to one of the most ancient layers of vocabulary, since the establishment of kinship relations took place in parallel with the formation and development of society itself.
