In terms of cavern dwelling Duskwight Elezen in particular, I imagine that they might have something of their own language as well, if not several variants. I think it was mentioned somewhere before (I want to find the source for this) that they may have various signals between sort of echoing cave wall-tapping like Morse code almost. I'd think too, they could have different spoken languages considering their seclusion from the outside world. And then if you figure in the potential for individual clans... I can see them having either dialects, or entirely familial-specific languages.
If you merely live among the same group for generations, without much outside contact (depending on the degree of seclusion) I figure it'd be pretty conceivable to have a language sort of evolve that only particulars of that group can fully grasp.
But that's mostly speculation, and likely dependent on conditions.
