A variant or close equivalent of Taniquetil (WJ/403), this name is glossed “High Shining White Peak” (WJ/416) and seems to be a compound of ar(a)- “high”, fanya “cloud; white and shining [thing]” and rassë “horn (of animals and mountains)”. It is attested only in the Quendi and Eldar essay from 1959-60; the name Taniquetil is much more common.
