ㅅ 불규칙
Meaning
ㅅ-irregular verbs
How to use it
In ㅅ-irregular verbs, stem-final ㅅ drops before a vowel, but the two vowels do NOT contract: 붓다 → 부어요 (not 붜요). Regular ㅅ verbs (씻다, 웃다, 벗다) keep the ㅅ. Common irregulars: 짓다(build), 낫다(heal), 젓다(stir).
ㅅ drops but vowels stay separate (부어, not 붜).,씻다/웃다/벗다/빗다 are regular.
Examples
| Korean | English |
|---|---|
| 붓다 → 부어요 / 부었어요. butda → bueoyo / bueosseoyo. | pour/swell → pour(s) / poured |
| 낫다 → 나아요 (병이 나아요). natda → naayo (byeongi naayo). | heal → 나아요 (the illness heals) |
