"I don't know"/"I didn't know" in Korean Hi I have a couple of rather simple questions :) 1. What is "I didn't know" in Korean"? If "I don't know" is 잘 모르겠어요 (am I right?) does that make "I didn't know" = 잘 모르겠었어요? 2. "I don't know" can be translated to "몰라" but it is reduced to its informal form. May I know where the 라 came from? thank you in advance! :)
