The name "Crnica" for the olive variety and, by extension, for Crnica olive oil, originates from the Croatian word "crna," which means "black" in English. It likely refers to the dark color of the olives when they are ripe. Crnica olives are known for their dark purplish-black appearance when fully mature, and this characteristic likely inspired the name "Crnica" for both the olive variety and the olive oil produced from it.
