N. Arad Dain loc. “?High Pass”
An alternate name of Annerchi(o)n “Goblin Gate” appearing in the Lord of the Rings drafts from the 1940s, preceded by a rejected word Tar (RS/432). The meaning of the name is unclear, Roman Rausch suggested it might mean “High Pass” based on the rejected element Tar. He further suggested the initial element Arad may be derived from the root √ARA “noble” (= “high”) and the second element Dain is a variant form of dîn “pass”, though he also considered the possibility the meaning of the elements was reversed. See EE/2.6 for further discussion.
