Etymology.
The meaning of "tejen" is unclear. Atanyyazov explained, ...The meaning of this ancient name is not clear...Barthold noted that this name was also used in the form of Tuzhen in the X-XI centuries...Vambery derived it from the words "tei-e hend" ("tei-e kent", "tei"— “down”, "kent" - “village”, “city”) and derived from that “downstream of the city,” “downstream of the city,” or “downstream of the river". He writes that he may have understood the meaning of the word as "city in the desert"...the name of the village along the Gerrud River is mentioned...This name also means "the foot of the city"...As Barthold rightly points out, this name is not the name of the first river, but the name of the county, village, or land, for the river itself is in its upper reaches Hererrud (Herat-rud, i.e., the "Herat River"), and below Sarahs is Khushk-rud, i.e., it was known as the "Waterless River"...In Persian "khushk" means "dry", "shroud", "rud" - "river". This name is a characteristic sign of the river, that is, it is associated with the cutting off of its water in the summer.
