Word derivation for "isle":
Basque = irla, Finnish = saari
Miresua = ilari
Back to geography terms. This is the Miresua word for isle, a smaller island. I'll make another word for island, because Basque has another word for island that appears to be used for bigger islands, plus it's similar to the Basque word for archipelago.
The Basque word irla is from the Spanish isla which is from the Latin insula.
