Tergi

Tergi is a geographic name used in the Caucasus region, most notably as the local name for a river that is more widely known in English as the Terek River. In languages such as Georgian and some regional Caucasian tongues, the river is called Tergi, while in Russian and other sources it is commonly rendered as Terek. The river originates in the Greater Caucasus and flows southeast through the region, traversing national borders before draining into the Caspian Sea. Its watershed has historically served as a natural corridor that supported settlements, transportation routes, and agricultural irrigation in parts of the Caucasus.

The name Tergi also appears as a toponym for various geographic features and localities in the area, reflecting linguistic diversity and transliteration differences across languages spoken in the mountains and plains of the region. Because of these variations, maps and texts may use Tergi, Terek, or related spellings to refer to the same river and nearby places.

Etymology and usage: The form Tergi arises from regional language traditions, while Terek is the more widely used form in Russian and some international contexts. The two spellings refer to the same hydrological feature, with the different renditions reflecting historical and linguistic influences in the Caucasus.

Historically, the river basin has been associated with various empires and cultures, and remains an important geographical feature in the Caucasus for its natural resources and strategic location.
