A neologism for “to heal” coined by Helge Fauskanger for his NQNT (NQNT), the equivalent of [N.] nesta- “to heal”. I would use the attested verb Q. hasa- (haþa-) “to treat medically, help cure” instead (PE22/166).
Quenya
envinyata-
verb. to renew, heal, to renew, heal, *restore
nesta-
verb. to heal
A verb for “to renew, heal” implied by the names Q. Envinyatar “Renewer” (LotR/1110) and Q. Arda Envinyanta “Arda Healed” (MR/405). It is a combination of en- “re-”, vinya “new”, and the causative suffix -ta, so literally “✱to make new again”. Hence “renew” or “✱restore” is probably a more accurate translation than “heal”.
