- Arsov — A proper surname of Slavic origin (frequent in Bulgaria and North Macedonia), derived as a patronymic from the given name Arso, a shortened or hypocoristic variant of the name Arsenie (Arsenios). This name identifies specific genealogical lineages within the Balkan region, periodically appearing in border records or ethnic communities in southern Romania.
- Bahna — The name of a commune and its administrative village in Neamț County, Moldavia, Romania; it also designates several small streams and rural localities across Bacău, Mehedinți, or Suceava counties. Etymologically, the term derives from an ancient Slavic or Ukrainian root (bahno) meaning 'swamp', 'mire', or 'muddy place', reflecting the original geographical characteristics of the local terrain.
