Sergeyevich

Sergeyevich is a Russian patronymic used to identify a male as the son of a man named Sergey (also Sergey or Sergei). In the Russian naming system, a person typically has a given name, a patronymic, and a surname. The patronymic Sergeyevich is formed by adding the suffix -yevich (or -evich) to the father's name, producing a meaning equivalent to "son of Sergey." The feminine form of the patronymic is Sergeyevna.

Patronymics are used in formal address and in official documents to indicate paternal lineage. In everyday life, people are often addressed by their given name, but in formal or respectful contexts a person may be called by their given name plus patronymic (for example, Ivan Sergeyevich). Sergeyevich is commonly spelled in English as Sergeyevich or Sergeevich; in Cyrillic it is Сергеевич. Variants and transliterations reflect different transliteration standards from Russian.

The use of the Sergeyevich patronymic is widespread across Russia and other Slavic-speaking regions, including Belarus and parts of Ukraine. Regional or contextual variations can affect how commonly patronymics are used in speech or formal settings. As a linguistic feature, Sergeyevich, like other patronymics, serves to convey family ancestry and social formality rather than a fixed surname.
