I just started learning Korean today and I tried to do the review section of chapter 2 in Vitamin Korean 1 but got stuck in question number 17.
In this question, it asks to choose the wrong choice from the underlined part, which are:
- 할머니가 보세요.
- 어머니가 드세요.
- 할아버지가 자세요.
- 아버지가 말씀하세요.
The book shows that the answer is number 3, but I don’t get it. Because 자다 is a verb. So, why this choice is wrong when followed by -(으)세요 likes other choices?
Maybe I skipped some grammar rule? Could someone help me to clarify this for me?
Thank you in advance!
