Yeah, there're some accents in Korean. I have a thick southern accent and thin one, but it's nothing you need to bother as Hujok says. Every accent is easily understood, the matter is the local dialect.

What do u mean by "accent"? If it s stress on some syllables, it s very weak in Korean, u dont really need to bother.

I think every language has an accent, and it depends where it is put. in English, accents are put in syllables whereas we put accents in words not syllables.

I guess there is.:)
