I'm Not a Bad Person.
나쁜 사람 아닌데
나쁜 or (Na-ppeun) = Bad.
사람 or (Saram) = Person. (Little Side note: if you add 들 or Deul after 사람 or Saram, it changes the entire sentence to "They are not bad People.")
아닌데 or (Ah-neen-deh) = "it's Not" or "__'s Not." (It's a term of Negation)
I Hope that this helps you out. Don't ever give up on Learning Korean. You can Do it! 🤗✌️
