Interesting that you should bring this up, Jeff. As an editor, how would you spell that word normally? I'd spell it "huh." But to me, "hunh" is a Brokieism itself. Maybe because that looks more like the way Ennis pronounces it? For whatever reason, that spelling is so common at BetterMost that, while I might not use it when writing something for somewhere else, I ALWAYS use it here. It connects me with my Brokie identity. I have talked other Brokies into switching to that spelling, too.
I always spelled it 
huh also, until I picked up 
hunh here. Using 
hunh to my supervisor was kind of like making an inside joke with myself; I'm sure she had no clue, maybe didn't even notice the 
n.I have come to the opinion, though, that adding that 
n does convey the nasal quality that many people, including me, and not just Heath/Ennis, use when they make the inquiring noise customarily spelled 
huh.I really don't know who is responsible for adding that 
n, however.
