The name "Staroserb" has roots that can be traced through several historical sources. Records from the 14th century contain mentions of the names "Bujko" and "Bujsha," which, according to Y. Svoboda, derive not from a compound but directly from the adjective "buj" with the addition of the suffix "-ko." Additionally, one can note the Old Russian name "Buyan Zhkov," and the old Polish personal name from the 15th century "Bujak." These examples highlight the development and evolution of names in East Slavic cultures.
