Does it piss you off when people pronounce manga with a long "a"?

No, of course not. It's about the closest you can get to the Japanese pronunciation with English phonemes; why would it? I don't understand what people have against this...

No.
Manga can be pronounced either way. I pronounce it with a long A cuz thats how you say it in America!! ^^
People prounce anime with a short A, but thats wrong. Because 'anime' is short for 'animation'.

No, because that's how I pronounce it.

I never pronounced it right until two years ago. I finally got into the habit of pronouncing it right a taon ago. Therefore, i dont have the right to be annoyed.

I had to look up what the long "a" sound was x_x Haven't heard it worded like that since Elementary school and it doesn't really make sense since I take the same amount of time to pronounce it long or short ;P

ANYWAYS, no it doesn't bother me. If they don't know the language how are they supposed to know how to pronounce it correctly and what sounds do or don't exist? I didn't get mad at my dog the first time she peed in the house when she was a puppy. Many of us don't speak Japanese so our mouth muscles have trouble forming sounds that aren't comfortable and/or don't roll off the tongue as easily as in our mother tongue. For a lot of people m-a-nga is madami comfortable than m-ah-nga.

Nope! 'Cause I used to pronounce it like that till someone corrected me.

Uhh...

I say it that way because people understand me if I do that. (some of the people in the netherlands don't even know what manga is....O_o)

Nerrrr. Butt it peeves me of a little when they pronounce it like, "munnga"

YES. I'm a real stickler for proper pronunciations, spelling, grammar, and language rules. I don't know why, but people misusing language, it's something that's always bugged me. = /

yes finally someone who feels the sameway
