Semyonovich

Semyonovich is a masculine patronymic form used in Russian and several other Slavic languages. It means "son of Semyon" and is formed from the given name Semyon (a form of Simon) with the patronymic suffix -ovich. The feminine form is Semyonovna. In some transliterations it appears as Semenovich or Semionovich.

Origins and usage notes indicate that in traditional Slavic naming, a person’s full name can include a first name, a patronymic, and a surname. The patronymic is derived from the father’s given name and serves to indicate lineage. Semyonovich specifically denotes that the bearer's father was named Semyon. The form is common in Russia, Ukraine, and Belarus, with regional spellings such as Semenovych in Ukrainian.

As a patronymic, Semyonovich is typically not used as a surname in everyday life; however, it may appear as a family surname in modern times, especially after migration or name adaptation. In some cases individuals or families adopt the patronymic as a surname, and historical records may list Semyonovich as a last name.

Variations exist across languages, with Ukrainian often rendered as Semenovych. Related names include Semenov or Semyonov as surname forms derived from the same root, and Semyonova or Semenova as feminine surname forms.
