öa

adverb. away (of movement)

An adverb meaning “away” derived from √AWA of the same meaning (PE17/24). In Definitive Linguistic Notes (DLN) written in 1959, öa meant “away of movement” and was contrasted with au “off, away, not here, of pos[ition]” (PE17/144). In the Quendi and Eldar essay of 1959-60, Tolkien said “the [primitive] form awā appears originally to have been used either of rest or motion, and öa can still be so used in Q.”; it was contrasted with öar for motion away (WJ/366).

Neo-Quenya: For purposes of Neo-Quenya, I would assume adverbial öa is a generic “away” usable either for being or moving away, while au is only being away and öar is only moving away.

öa-

verb. to possess, own, keep

A verb Tolkien coined in Late Notes on Verb Structure (LVS) written in 1969 (PE22/155-156) to have the meaning “possess, own, keep (have in hand, use or with one)” (PE22/151). It was derived from the root √AW, apparently not in its usual sense “away”. Tolkien considered two base forms: auta- with pasts au̯ante, oante, vante, or oa- with past aune, future auva, and alternate present āva. Since auta- clashes with better known auta- “depart”, I recommended using oa- “possess, own, keep” for purposes of Neo-Quenya.
