keulo = school (noun) (some things Google found for "keulo": an uncommon to rare term; user names; name of a Senegalese music album by Pape Kanouté; an unusual last name that may be Slovenian)
Word derivation for "school" :
Basque = eskola, Finnish = koulu
Miresua = keulo
This Miresua word looks more like the Finnish word, but it's an even mix of letters. I was trying to avoid having the Miresua word look too much like the Basque word, because that looks like the Latin word for "school" which is "schola".
