verb. to change [self], alternate
virya-
verb. change, alter(nate)
virya
fresh
virya (1) adj. "fresh" (VT46:22)
vistë Reconstructed
noun. change
This word is unattested, but there is indirect evidence for it as an element of walwistë “change of mind” (PE17/189). This word likely contains the archaic form †wistë from before the change of w- to v-. Its modern form would be ✱vistë. If you accept inwist- as the stem form of inwis “change of mind”, it likely contains †wistë as well.
There is another attested word wirnë with the gloss “change” (PE17/191), but I think it is likelier to be the archaic form of the strong-past tense of the verb virya- instead of a noun.
Víressë
april
Víressë noun, fourth month of the year, "April" (Appendix D). The Quenya name is apparently related to words for youth and freshness; compare vírië, virya.
ahya-
verb. change
#ahya- vb. "change" (intransitive), only attested in the past tense: ahyanë (PM:395)
ahya-
verb. to change
A verb for “to change” appearing in notes from the 1950s implied by its past tense form ahyanë “did change” in the phrase manen lambë Quendion ahyanë “How did the language of the Elves change?” (PM/395).
céva

vista- (2) vb. "change" (transitive), pa.t. vistanë, cf. intransitive virya-, q.v. (PE17:189, 191)
wirnë
change
wirnë noun? "change" (PE17:191)
wirnë
noun. change
wistë Reconstructed
noun. change
An intransitive verb meaning “change [self], alternate” based on the root √WIS “change” (PE17/189, 191). For change of others, use transitive vista-.
One form of this word, wirnë (PE17/191), is unclear in function. It is glossed “change” and could be a noun. However, it almost identical in form to the strong-past virne of virya- attested on PE17/189. It seems likelier to me that this is the archaic form of the strong-past tense from before the change of ✶w- to v-.
Evidence elsewhere suggests the noun form of “change” is vistë; see that entry for discussion.
