Name that Túrin gave himself in the earliest Lost Tales (LT2/89), apparently a combination of an otherwise unattested adjective ✱rúse “weary”, taure “forest” and the patronymic -ion “son”. Christopher Tolkien suggested its initial element may be related to rûs “endurance, longsuffering” (LT2A/Rúsitaurion) and thus not a direct cognate of the equivalent element G. drauth of the Gnomish version of this name: G. Drauthodavros.
