Froggagogi

This language is understood by frog-based animalians, but the linguistic magic breaks only when referring to the language itself. Froggagog is what it is called in Gether, but Skyfell characters with this language will call it something entirely different.
Froggagog is included in the Gether Guide to Languages on DrivethruRPG:
