The Târnava flows into the Mureș after 23 km[2][3] near the town of Teiuș.

Its drainage basin covers an area of 6,253 km2 (2,414 sq mi)[2].

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].
