I in fact DO pronounce it correctly.
Unfortunately most others do not. I've yet to hear a D&D player say it correctly let alone a non-D&D player.
Please get off the high horse (again) mourn.
Or maybe we should just drop all words from D&D that some people might not pronounce correctly?
Deva is a lot easier to guess the correct pronunciation of than "aasimar" is.Isn't that why they're getting rid of the name Aasimar?
Is it? I imagine a lot of people, when first confronted by the word, would pronounce it "diva".
And if it conjures the vision of a celestial in a little black dress singing 'Queen of the Night,' so be it.
I still like it better than Aasimar, which has one too many 'a's in it for my liking.
