@Scarifar@Kho I'll pull up a couple of relevant posts:
https://www.roleplayerguild.com/posts/3488019Back in page 8, Ilunabar sowed the seeds of language diversification. Sculptors were notably immune, maintaining the god-tongue and acting as universal translators. Angels, Pronobii and to an extent Lifprasilians, with their small localised populations and close connection with their gods, were also largely exempt, although language diversification could still occur if conditions changed.
https://www.roleplayerguild.com/posts/3523944Here Termite explores some of the mortal languages. If I remember correctly, Termite's head canon is that the Angels speak Yiddish or some variant thereof, although in light of my previous statement the angels probably all still have a language close to the god-tongue.
The Lifprasilians of Alefpria, the Angels, the Sculptors, and the Quara Korala would all speak the god-tongue or some language fairly close to it.
