The subject of the article is the integrating influence of the Slavic languages as languages used by the majority of society for anthroponomastic systems derived from other cultures, religions, and languages in the field of feminine given names and hypocoristic forms, created from both maculine and feminine first names. Feminine given names of Slavic origin had almost exclusively the ending –a, which also appears, almost without exception, in traditional Christian given names borrowed from various languages; newer names conform to this type in accordance with their popularity. This also applies to given names used by Muslims whose native tongue is a Slavic language, but also to the given names of non-Slavic peoples of the former U.S.S.R. who live sharing the same territory as the Russian populace. A similar process took place or is taking place among the Jewish populace being integrated (especially after World War II) with a local Slavic community. The Slavic model of hypocorization of names has a lesser extent. It encompasses given names of various provenance, but only when the native tongue of the populace is a Slavic language. It is not known, therefore, among the Muslim population of the former U.S.S.R.
