Yevdokim is the Russian form of Eudokimos, a Greek name derived from the elements eu meaning "good" and dokimos meaning "approved, esteemed," thus conveying a sense of "in good repute, honoured." The name entered the Russian naming tradition through the Christianization of Kievan Rus' in the 10th century, as the Orthodox Church adopted numerous Greek names with positive Christian virtues. Its feast day in the Orthodox calendar falls on July 31 (July 18 Old Style), commemorating Saint Eudokimos of Cappadocia, a righteous layman who lived in the 9th century.Etymology and Historical ContextAs a borrow from Greek, Yevdokim reflects the linguistic transformation characteristic of names crossing linguistic boundaries—Greek Eudokimos adapted to the Russian phonological system, with the initial Eu- becoming Yev- and the suffix -os dropping, producing a distinctly Russian-sounding name. While globally uncommon, he name was fairly traditional in Russia, sometimes as a monastic name of signifying virtuous characer.Notable BearersYevdokim Gershtein (d. 1968), Russian physiologist known for research in blood coagulation
