The thing was already quite fouled up in Late PIE, and 'to be' was not a morphologically stative verb. Things also were fouled up in Hittite, though in a different way - which endings a verb used was specified lexically.Tuyono wrote: ↑10 May 2019 22:05Thanks for the answer! So in that system, how do you describe a state that's in the past and no longer true? Also, was "to be" a stative verb or not?
In my conlang Old Albic, which represents a branch of IE which diverged before these things were fouled up, stative verbs are inflected for tense normally. I am not sure yet about aspect, but stative verbs at least have a gnomic aorist (a perfective form used to make statements that are always true). Old Albic has two verbs 'to be', roughly equivalent to Spanish ser and estar, and both are stative.
