The name Târnava is of Slavic origin from trn,^[5] 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^{[citation needed]}"; or a reference to the Romanian city of Turda, forming Tur + ava from dava^{[citation needed]}.

Trn (thorn) is used by Slavic peoples in the Balkans, Czechia and Slovakia, but the 60% R1a Slavs (Poles, Belarusians, Russians) say syp/ship^{[citation needed][weasel words]}.

The Hungarian name Küküllő is of Old Turkic origin from kukel meaning sloe, and is thought to have originated from the Avar people^{[citation needed]}.
