virya-

verb. to change, alternate

This verb is intransitive, so it can be used of change of self but not of others. For change of others, use vista-.

One form of this word, wirne (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 likely 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.

virya-

change, alter(nate)

virya- (2) vb. "change, alter(nate)" (intransitive), pa.t. virnë/virinyë, cf. transitive vista-, q.v. (PE17:189, 191)

wirnë

noun. change

@@@ Despite its gloss, wirnë might be the archaic strong past tense of virya-: it is almost identical to the strong past tense form on PE17/189. For a noun form, vistë may be preferable.

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 wirne 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.
