Just want to point out that draconic has quite a lot of words already defined, as well as a few grammar rules. 1. Draconic, 2. Draconic Primer, and 3. Lonely Planet Vayemniri (vayemniri being the endonym for dragonborn in the Realms—a race that absolutely despises dragons wouldn’t exactly be happy about a name that says "dragon").

I’m not sure what real-world language would be the best analogue. Maybe something Germanic?
