Etymology The name Târnava is of Slavic origin from trn, meaning "thorn". Other proposed origins for the river's Romanian name is Turn (tower) + dav from Dacian dava (structure/fortress), i.e. "the river that flows amongst towers and davas"; or a reference to the Romanian city of Turda, forming Tur + ava from dava. Trn (thorn) is used by Slavic peoples in the Balkans, but the 60% R1a Slavs (Poles, Belarusians, Russians) say syp/ship. The Hungarian name Küküllő is of Old Turkic origin from kukel meaning sloe, and is thought to have originated from the Avar people.
