Can someone please tell me how to say 'I don't know' in Korean? specifically in Busan dialect
I'm trying to learn Busan dialect better by myself since i know only basic standard Korean and I'm going to be studying/moving to Busan next year and my mother refuses to properly teach me because she thinks we should only speak english since we live in America t___t this is all I need to know for now but I will probably be back with more questions sooner or later haha

Question

Answer

몰라 , 모른다.
모르겠는데요?

Answer

모르다 (몰라요, 모르겠어요) 
You can always add 잘 to make it stronger. 
I lived in Busan (that's where I learned my Korean), and there wasn't really a way to say that in the dialect. If there was, no one around me (students, teachers, family, etc) ever used it. A slang-ish way to say it would be 모르겠으 where you basically hold the "SS" sound for a longer amount of time with no actually ending vowel. I hope I helped! ^^ Good luck! Busan dialect is so much fun~
