The language has been called a great number of things by many different people - Dovah, Dragon, Dragontongue, Thu'um ("the Voice"), Dovahzul, Dragon Language, Tinvaaksedovah just to name a few that I've seen.
I have always taken to calling it the "Dragon Language" (in Cyrodiilic, anyways). What should we name the language, both internal (in the Dragon Language) and external (in Cyrodiilic)? There are the options above, as well as some others we can make from the language itself: Sahkrensedov, Deinoksedov, Dovahsahkren, Dovahdeinok ...
I will personally most likely contiue to call it the "Dragon Language", but I'm open to suggestions as far as what the language calls itself. "Thu'um" has my vote - it's short, and everyone knows what it means already. Although, we can also debate that the Dragon Language is separate from actual power of "The Voice". Also, I know a lot of people who call it by "Dovahzul" and that works very well too.
Thoughts?
