The name "Buna" has Slavic origins and is a truncated-suffix male personal name. It is derived from the South Slavic verb "bunitі," which means "to encourage," "to stimulate," or "to rebel." This name was used not only among Ukrainians and Moldovans but also among the Zakarpattia Vlachs. For example, in 1365, an individual named "Buna" is mentioned in a historical document: "Dragomer cum filius romani de Korumle, cum Kaliman, Buna et Kalym olachis."
