부정문 — Negative Sentences
Korean has two ways to negate verbs: short negation (안) and long negation (-지 않다). Both mean the same thing.
Short negation: 안 + verb
| Positive | Negative |
|---|---|
| 가요 (go) | 안 가요 (don't go) |
| 먹어요 (eat) | 안 먹어요 (don't eat) |
| 좋아해요 (like) | 좋아안 해요 ✗ → 안 좋아해요 ✓ |
Long negation: verb stem + -지 않아요
| Positive | Negative |
|---|---|
| 가요 (go) | 가지 않아요 (don't go) |
| 먹어요 (eat) | 먹지 않아요 (don't eat) |
| 공부해요 (study) | 공부하지 않아요 (don't study) |
하다 verbs with short negation: For compound 하다 verbs, 안 goes before 하다: 공부 안 해요 (NOT *안 공부해요). But 안 좋아해요 is also acceptable.
Special negatives (inherently negative words):
- 없다 (not exist/not have) — already negative, don't add 안
- 모르다 (not know) — negative of 알다 (know)
- 못 + verb = cannot (inability): 못 가요 (can't go)
못 vs 안: 안 = choose not to (won't). 못 = unable to (can't). 안 먹어요 (I don't eat it — choice). 못 먹어요 (I can't eat it — unable).
Common Error Patterns
Placed 안 in the wrong position (e.g., before compound noun instead of before 하다)
Simple verbs: 안 + verb (안 가요). 하다 compounds: noun + 안 + 해요 (공부 안 해요)
Confused 안 (won't/don't) with 못 (can't)
안 = voluntary choice (I won't). 못 = inability (I can't). 안 먹어요 (won't eat) vs 못 먹어요 (can't eat)
오늘 안 가요.
I'm not going today.
Short negation: 안 placed directly before the verb. 오늘 (today) + 안 + 가요 (go) = I'm not going today.
매운 음식을 먹지 않아요.
I don't eat spicy food.
Long negation: verb stem + 지 않아요. 먹 (eat stem) + 지 않아요 = don't eat. More formal/emphatic than 안 먹어요.
수영을 못 해요.
I can't swim.
못 = can't (inability). 수영 (swimming) + 을 + 못 해요 (can't do). Compare: 수영 안 해요 = I don't swim (choice).
공부 안 해요.
I'm not studying.
하다 compound verbs: 안 goes between the noun and 하다: 공부 + 안 + 해요. NOT *안 공부해요.
