sodalti = soldier (noun) (some things Google found for "sodalti": a rare term; an unusual last name; there's a Villa Sodalti in Buenos Aires; similar word "sodalitas" means "fellowship, association, companionship, secret society" in Latin)
Word derivation for "soldier" :
Basque = soldadu, Finnish = sotilas
Miresua = sodalti
I started my Miresua word with "so" because both the Basque and Finnish words for "soldier" (and the English!) start that way. According to Wikipedia, the English word "soldier" is derived from the Latin "solidarius" which means someone who served in the armed forces for pay.
