Example sentences

How it’s used

울다 means to cry, and it is also used for some animal and insect sounds: 새가 울어요 (“a bird is singing”), 매미가 울어요. Its opposite is 웃다 (to laugh). As an ㄹ-stem verb it drops ㄹ before ㄴ, ㅂ and ㅅ: 웁니다, 우세요, 우는 아이.

Common mistake

Keeping the ㄹ before ㄴ: ✗ 울는 아이 → ✓ 우는 아이 (“a crying child”).
