It's confirmed that the races DO have their own languages, but they're more like old languages. Roegadyn still use their language for names and the lore forum has a dictionary up for it. Elezen have a sort of french based language that they haven't mentioned much about. It's mentioned that before moving to Eorzea, Miqo'te had a different language, but I think that's really all there was to that, too. I'd try picking around the naming conventions posts in the lore forums for more specifics, as I'm just going off memory. Here's a link!

I'd say it's possible for someone to have grown up mostly alone, especially in the twelveswood, though maybe not without ANY human contact. I think an adapted concept like the one you mentioned would be totally possible as long as you're cool with people thinking of your character as a wild, possibly crazy man. But that might be the point, no? : P
