Biblical Lake Gegharkuni (Sea of Gegham) Geghama tsov. Turkic-Azerbaijani: Gökçe or Göyçə. On Russian map of 1902 the name of the lake is given as "Gokce or Sevanga". The name Sevan literally means "Black Van" referring to Lake Van. It is said that long ago, Armenians came from the areas around Lake Van to Lake Sevan. They saw that the lake was dark and almost black yet reminded them of Van, therefore the lake was called Sevan. The Old Georgian name for the lake drew from the name of its [color="Sienna"]old inhabitants (i.e. before the fall of Urartu), the [color="Sienna"]Èrs- it was called "Lake Ereta" by Leonti Mroveli in his Georgian Chronicles.

Finally, the etymology of word "Sevan" was found in Teyseba (the cuneiform inscription by Rusa I (730—714 B.C.)). This inscription was a "birth certificate" of the term "Sevan". It was mentioned as "Suinia" or "Tsuinia". Thus, the etymology of "Sevan" is similar to Yerevan's etymology.
