Yefimovich
Yefimovich is a common Russian patronymic, derived from the given name Yefim. Patronymics are an integral part of Russian naming conventions, traditionally indicating descent from the father. In this case, "Yefimovich" signifies "son of Yefim." While it is not a surname in the Western sense, it functions as a surname in many official contexts in Russia and other Eastern European countries where patronymics are used. The given name Yefim itself has Greek origins, meaning "well-spoken" or "auspicious." The use of patronymics, particularly in conjunction with a given name and surname, is a deeply rooted cultural practice that continues to be observed in modern Russia, though its legal standing and daily use can vary. Individuals with the patronymic Yefimovich would have a father named Yefim.
