onivan = were (verb "to be"/"to exist" - past tense - they were - 3rd person plural) (some things Google found for "onivan": a rare term; user names; nearly all the letters of the last name or first name "Donivan"; a rare last name)
Word derivation for "they were" (to exist) :
Basque = ziren, Finnish = olivat
Miresua = onivan
This ends my conjugations of the verb to be/to exist in the past tense. Next up, a couple of nouns.
This Miresua conlang word has been changed. This word didn't follow my established rules. The word for "they were" is now "onivet".
