Explanation

잘 모르겠어요 literally means “I do not know well,” but it naturally communicates “I do not understand” or “I am not sure.”

It is softer than a blunt “no.” Use it when directions, explanations, or a question are unclear.

For spoken Korean that you cannot hear clearly, 잘 못 들었어요 means “I did not hear well.”

Examples

죄송하지만, 잘 모르겠어요.

Joesonghajiman, jal moreugesseoyo.

Sorry, but I do not understand.

잘 못 들었어요.

Jal mot deureosseoyo.

I did not hear well.

Common mistakes

  • 모르겠어요 is not the same as 몰라요; 몰라요 can sound much more casual or abrupt.
  • Use 못 들었어요 for hearing, not 모르겠어요.

How to practice

  1. A polite, humble phrase for learners.
  2. Add 죄송하지만 (“I am sorry, but”) for extra politeness.
