It is believed the origin of the name Tirich Mir is King of Tirich as Tirich is the name of a side valley of the Mulkhow valley of Chitral which leads up to Tirich Mir. An alternative etymology derives this name from the Wakhi language. In Wakhi, trich means shadow or darkness and mir means king, so Tirich Mir means king of darkness. It could have gotten this name as it creates long shadows on the Wakhan side of its face.
