fospa : foxes
The Illunse word for foxes (nominative plural) is fospa. FOSPA is an acronym for a several associations.
Foxes in Latin is vulpis. Foxes in Old English is foxas. Although both plurals end in -s, I decided to do something different for Illunse. My rationale is geeky, so I'll just say I'm doing this for esthetic reasons.
Fox in Illunse is fospe, which is a mix of the Latin word (vulpes) and Old English word (fox).
