Isajev

Isajev is a surname of Slavic origin, primarily found in Russia and other East Slavic regions. It is a transliteration variant of the Russian surname Isaev (Исаев), derived from the given name Isa, a form of Isaiah, with the patronymic suffix -ев indicating “belonging to” or “son of.” The root Isa is linked to the Hebrew name Yeshayahu (Isaiah), meaning “Yahweh is salvation.” The feminine form is Isaeva (Исаева).

Variants and transliteration: Depending on language and transliteration system, Isaev can be rendered as Isayev, Isaieff, or Isajev. The form Isajev is common in German- and Baltic-influenced records, where j often represents the й sound.

Geographical distribution: The surname is most frequent in Russia, Ukraine, and Belarus, with presence in other former Soviet states. Diaspora communities in Germany, Israel, the United States, and elsewhere also bear the name.

Usage and form: As a patronymic-based surname, Isajev indicates descent from an ancestor named Isa. In modern use, it is a fixed family name; gender forms include Isajev (masculine) and Isaeva (feminine).
