The term of kinship appeared in the earliest period of human history - in a primitive society, at the time when system of private property had not yet emerged. Naturally, the Uzbek language is not an exception. The historical period of forming of kinship terms in Uzbek language is divided into the following groups: a) archaic terms - commonly used in the history of the Uzbek language, now not use in speech practice; b) ancient terms - oldest terms that are used in speech practice; new terms - terms of kinship, which appeared in the formation of synchronous norms of the Uzbek language. In the article, these moments were specially analyzed.
