Word derivation for "sister" :
Basque = ahizpa, Finnish = sisar
Miresua = ahisa
My previous word for sister was sazri.
My Miresua words for daughter and girl both look more like Finnish, although they are a mix of letters from the Finnish and Basque words. So to be fair, I'm changing this word so that it's more like Basque.
This Miresua conlang word has been changed. The word for sister is now aizar.
