Questions & Answers about seonsaengnimkke jilmunhal ttaemada ginjangdwaeyo.

Why is 께 used after 선생님?

께 is an honorific particle meaning something like to when the person receiving the action deserves respect.

So in 선생님께 질문할 때마다, the speaker is showing politeness toward the teacher.
A less honorific version would be:

• 선생님에게
• 선생님한테

Those are also grammatically possible, but 께 sounds more respectful and is very natural with 선생님.

Why is it 질문할 instead of 질문을 할?

Both are possible.

• 질문할 때마다
• 질문을 할 때마다

Here, 질문하다 means to ask a question. Since 질문하다 is a noun + 하다 verb, Korean often drops the object marker 을/를 in these combinations when modifying a noun like 때.

So 질문할 때마다 is just a slightly more compact, natural version of 질문을 할 때마다.

What does -할 때마다 mean exactly?

때마다 means every time or whenever.

Breakdown:

• 질문하다 = to ask a question
• 질문할 = asking / when asking
• 때 = time, when
• 마다 = every, each

So 질문할 때마다 means every time I ask a question or whenever I ask a question.

It is stronger than just 질문할 때, which would mean when I ask a question.
Adding 마다 gives the sense of repetition: it happens every single time.
