Quick Quiz 🎯

  1. 비 → 비______
  2. 바람 → 바람______
  3. 친구 → 친구______
  4. 버스 → 버스______

Answers: 비가 / 바람이 / 친구가 / 버스가

Answering “who?”

A: 누가 민수 씨예요? — Who is Minsu?
B: 제가 민수예요. — I’m Minsu.

제가 and 저는 are both useful

제가 is 저 + 가; do not write 저가 for this meaning. In the dialogue, 제가 identifies the person the question asks about. 저는 민수예요 is natural when introducing yourself as the topic. Avoid a rule that says one particle always means “I” and the other does not: both can follow a word referring to the speaker.

Practice in context

Complete the answers with 이 or 가: ① 뭐가 있어요? 책___ 있어요. ② 누가 와요? 친구___ 와요.

Answers and explanation

① 책이 있어요. 책 ends in ㄱ. ② 친구가 와요. 친구 ends in a vowel. For the question word 누구, the usual combination with 가 is 누가. Ask 누가 와요? and give a new answer using a name.
