Name (Etymology)
Zachlumia is a derivative of Hum, from Vulgar Latin (Vlach) culme (Latin: culmen) meaning "Hill". South Slavic Zahumlje is named after the mountain of Hum (za + Hum "behind the Hum"), above Bona, at the mouth of the Buna. The principality is named Zahumlje or Hum in Bosnian, Croatian and Serbian (Serbian Cyrillic: Захумље, Хум). It is Zachlumia in Latin, Хлъмъ in Old Church Slavonic, and Ζαχλούμων χώρα ("land of Zachlumians") in Greek. The names Chelmania, Chulmia and terra de Chelmo appear in later Latin and Italian chronicles.
