I think someone else wanted Irthos to have a distinct language. I find it interesting that Landadel is brimming with derivatives while the three nations on the Inner Sea all share a language, too, but I'm not really opposed to such developments.
Languages tend to diverge where they're isolated -- often by mountains or other impassible terrain. Impassible terrain also tends to favor smaller states and countries, because you can't exactly sweep an army through a continent full of mountainous terrain and then maintain an empire that standardizes the language over the course of a century or two. I was making the leap that the multiple baronies in Landadel probably meant mountains or other impassible terrain, which meant lots of language divergence. With the Inner Sea keeping most of the surrounding lands in easy contact via sailing, and also having larger government units, the languages would tend to diverge less.
Realistically, a place like Landadel should have about 30 languages instead of four, and the Inner Sea should have a half-dozen, rather than one. But I think that's an Acceptable Break from Reality.
Uzka Mor for Inner Sea.
Bergnsprak for Stonetongue
Ogof'iaith for Cavetongue
Norey Jan for Northern Ilse
I'm generally a little wary of not having a clear link between the name of the language and its origin, because it gets hard to remember what maps to what, especially as the world grows.
