The language seems to have a very Nordic/Germanic feel to it, as well as a few English flecks here and there. Paarthurnax and I were discussing about how best to pronounce 'J' in a word.
I think, personally, the Dragon Language has strong Nordic roots, and in languages like Norwegian 'J' is pronounced as a 'Y' sort of sound, think "Hjerim" which sounds more like "Yerim", or the Norwegian word "Kjæledyr", which sounds more like "Shall-dir". It would allow much more interesting sounding words, but it would mean that any existing words would need to be examined and altered, or exceptions placed.
Any thoughts?
