Word derivation for "ass" (or "arse") :
Basque = ipurdi, Finnish = perse
Miresua = irpe
As in English, this word can be used as a profane term for the buttocks or a mild swearword.
Usually I like to make my Miresua words the average length of the Basque and Finnish words. This word is a letter shorter, but that is within my allowable range. At four letters, it's an even alphabetic mixture -- it contains the two common letters (p and r) and a vowel from each the Basque and the Finnish words.
