Have you ever invented your own languages?

[vorpal blade]

Yes I did! It was a bit primitive perhaps, and had a large amount of compound words, but it existed. I even made up a world in which they lived, complete with countires, social classes, and ancient histories comprised of the various other attepts I had like this. I also had a 36 character alphabet derived from sign language letters. It was awesome, and I still use it a little, primarily as an ancient or sometimes elven language in my games. Cool thing was, my name (eric) meant "meteor" (eh= up, sky, and such+ rrahk=rock. sky rock= meteor).

I'm going to add to my post in saying that in addition to the 36 letters (about 11 vowels) I had fiddled with a typre of "condensed" writing in which the vowels were paired with consanants to make syllablistic characters.
