byelorussian

The term 'Byelorussian' is a direct Anglicization of the Russian name "Белоруссия" (Belorussiya), which itself is a compound. The first element, "бело-" (belo-), means "white," a color term used historically in Slavic toponymy, often to denote a western direction or a "free" or "pure" land. The second element refers to "Rus'," the medieval East Slavic state and cultural region. Thus, the name literally translates to "White Rus'," a historical designation for the territory of modern Belarus, distinguishing it from other Rus' principalities like Black Rus' or Red Rus'. The modern term 'Belarusian' is now preferred, with 'Byelorussian' representing an older transliteration.
