Q. Aracorno m. “Aragorn”
A Quenya equivalent of Aragorn (PE17/71) of unclear meaning. It initial element is certainly ar(a)- “high”, but the meaning of its final element is uncertain. This name is inconsistent with the derivation of Aragorn from OS. Ára-ngorn “Revered King” (PE17/113), whose Quenya equivalent would probably be *Arangorno. Aracorno may simply be a phonetic adaptation of his Sindarin name.
