Ranilović
Ranilović is a Serbian surname. It is a patronymic surname, meaning it is derived from a male ancestor's given name. The name Ranilović is formed from the given name "Ranil" (a diminutive or derivative of names like Radoslav or Branislav, common Slavic given names) with the addition of the suffix "-ović," which is a common Serbian (and broader Slavic) suffix indicating "son of" or "descendant of." Thus, Ranilović signifies "son of Ranil" or "descendant of Ranil."
Surnames ending in "-ović" are characteristic of Serbian, Croatian, and Montenegrin surnames, and are also found in Bosnia and Herzegovina. The surname Ranilović, therefore, indicates a Serbian origin or heritage.
