Word derivation for "five"
Basque = bost, Finnish = viisi
Miresua = vosi
My previous word for "five" was "siboi". This word was changed because of the "oi" diphthong (neither the Basque word or the Finnish word has a diphthong) and because I somehow just didn't like that "siboi" was pronounced like SEE-BOY.
