Can the Celestial Tongue be spoken while in corporeal form? How about Helltongue?
The celestial tongue (“angelic”) cannot be spoken in a corporeal body except by Vassals of War (and possibly as a specific gift from other Superiors). “Humming” (In Nomine, p. 77, under Singing) is possible, though. The Helltongue can be spoken on Earth, since it has been corrupted for the pure celestial language. Angels, in general, do not know Helltongue but even those that do can take dissonance for lying in it! Demons can understand the celestial language but are loathe to use it.
