Korean grammar patterns › Level 2
-(으)ㄹ 줄 알다/모르다
know / not know how to (a learned skill)
Level 2 · TOPIK I · beginner
How to use it
Talks about a skill: whether someone has learned how to do something. Only with verbs.
Forming it
| 타다 | → 탈 줄 알아요 |
| 읽다 | → 읽을 줄 알아요 |
| 만들다 | → 만들 줄 알아요 |
| 수영하다 | → 수영할 줄 몰라요 |
It is about skill, not circumstances: if you can't come because you're busy, use 갈 수 없어요 (✗ 갈 줄 몰라요).
Examples
저는 아직 자전거를 탈 줄 몰라요.
I still don't know how to ride a bike.
김치찌개를 끓일 줄 알아요?
Do you know how to make kimchi stew?
Compared with similar patterns
-(으)ㄹ 수 있다/없다 covers both ability and possibility (time, permission, situation); -(으)ㄴ/는 줄 알다/몰랐다 means 'thought (wrongly) that / didn't know that'.
