Cernavodă 切尔纳沃德
Cernavodă (Romanian pronunciation: [t͡ʃernaˈvodə], historical names: Thracian: Axiopa, Greek:Axiopolis, Bulgarian:Черна вода Cherna voda, Turkish:Boğazköy) is a town in Constanţa County, Dobrogea, Romania with a population of 20,514.
The town's name is derived from the Slavic (more precisely Bulgarian) černa voda (черна вода in Cyrillic), meaning "black water". This name is regarded by some scholars as a calque of the earlier Thracian name Axíopa, from IE *n.ksei "dark" and upā "water" (cf. Avestan axšaēna "dark" and Lithuanian ùpė "river, creek").
