Dejan

Dejan (Cyrillic: Дејан) is a South Slavic masculine given name, derived from the Old Slavic word dejati, meaning "action; to act, to do". It is possible that the name is a diminutive of dithematic Desimir or Desislav, with des meaning "to happen". Although it is considered old Slavic name, some claim name Dejan comes from old Latin word Deus or Dea which mean God or Godly. It is very common in Serbia and North Macedonia, and also common in Bulgaria, Montenegro, Bosnia and Herzegovina, Croatia, and Slovenia.
