isaoni = grandfather (noun) (some things Google found for "isaoni": a rare term: user names; a rare last name)
Word derivation for "grandfather" :
Basque = aitona, Finnish = isoisä
Miresua = isaoni
This is a small change. My previous word for grandfather was isaioni, which was a compound word of father (isai) + big (oni). I decided that I did not like the three vowels in a row, so I dropped one letter. The Basque word for grandfather (aitona) doesn't quite start with the word for father (aita) either.
This Miresua conlang word has been changed. The word for "grandfather" is now "isaosa".
