Word derivation for "lake" :
Basque = laku, Finnish = järvi
Miresua = jaru
My previous Miresua word for lake was jirka. I think jirka looked too much like jerk. Also I'm simplifying this word.
This Miresua conlang word has been changed. I'm using aintzira as the Basque word. The word for lake is now ainäri.
