Questions & Answers about chekeu-inhal ttae sinbunjeungeul boyeo juseyo.
What does -할 때 mean in 체크인할 때?
-할 때 means when doing or at the time of doing.
So:
- 체크인하다 = to check in
- 체크인할 때 = when checking in / at check-in
Here, 하다 changes to 할 before 때.
A very common pattern is:
- verb stem + -(으)ㄹ 때 = when doing something
Examples:
- 먹을 때 = when eating
- 갈 때 = when going
- 체크인할 때 = when checking in
Why is it 체크인할 때 and not 체크인하다 때?
Because Korean usually does not put the dictionary form directly before 때.
Instead, you use the modifier form:
- 하다 → 할
- so 체크인하다 → 체크인할 때
This is similar to how Korean often changes a verb before a noun-like word.
So:
- 체크인하다 = to check in
- 체크인할 때 = when checking in
Using 체크인하다 때 would sound ungrammatical.
