Word derivation for "belt":
Basque = gerriko, Finnish = vyö
Miresua = gervö
Notice that the Finnish word contains an ö (o umlaut). I don't see too many of those, so I want to use it in my Miresua word.
All the letters in the Finnish word, vyö, don't even occur in the Basque language, which may be a first. I'm not entirely sure how to pronounce vyö. Both y and ö are vowels.
Finnish doesn't use the letter g, except in borrowed words. Miresua essentially uses the letters used in either Basque or Finnish.
