안 -
Quick answer: 안 - means not — put it in front of the verb.
How to form it
안 + verb · 안 가요 · with 하다 verbs it goes before 하다: 공부 안 해요
In Korean: 안 + 동사 안 가요 공부 안 해요
What to know
안 goes right before the verb. With 하다 verbs it slides inside — 공부해요 becomes 공부 안 해요, not 안 공부해요. This one trips up almost everyone, so say it aloud until it feels normal.
Examples
- 오늘 학교에 안 가요.I'm not going to school today.
- 밥을 안 먹어요.I don't eat rice.
- 오늘 공부 안 해요.I'm not studying today.
