Word derivation for "circle" :
Basque = zirkulu, Finnish = ympyrä (mpürä)
Miresua = pirüku
Previously the word for circle was pirykä. This minor change uses my conlang modification rule which allows two y's to be replaced by a ü, and changes the final vowel.
This Miresua conlang word has been revised to remove ü (u umlaut). The word for circle is now pyrku.
