There are a few sites out there that tell you a bit about the language, like words, spelling, grammar, etc. I'm still trying to learn as much as I can.
I know one of them offhand. Check out:http://www.eldalamberon.com/dni_dict.htm
(I'm not sure if the link will work. I'm new at this kind of thing. If it doesn't work, just write it down and go to the site manually i guess. It's a great help. Enjoy!)
