From Avestan 𐬆𐬭𐬆𐬑𐬱𐬀 (Ərəxša), of uncertain meaning, possibly from a root meaning "bear". In Iranian legend Arash was an archer who was ordered by the Turans to shoot an arrow, the landing place of which would determine the new location of the Iran-Turan border. Arash climbed a mountain and fired his arrow with such strength that it flew for several hours and landed on the banks of the far-away Oxus River.
