"Entombment" is spelled with -bm-, but the b is not pronounced. (As is also true of the root word "tomb".)

Yes, but spelling is what we're talking about, and in particular spelling in sign language, so pronunciation is irrelevant.

Well, I had shifted into pronunciation (mostly because in writing the concept of a "syllable" doesn't exist), but in the larger context, yes, that's fair.
