I am compiling a dictionary of three-letter words that pack a punch. These are my translations: please correct or respond as needed.
Most of these are used by dwarfs:
Aye: affirmative, yes, in a steady, forthright tone
Meh: Apathy, shrug, indifference, of no consequence
Bah: Dismissive interjection
Heh: A cross between a laugh and a smirk
Wee: Not used often, but heard it last night to describe a gnome, as in "The wee one" when I asked for clarification on a tank question. Since, as a draenei, I was not the 'wee one,' it was the frozen gnome.
Am still collecting. Meh.
