Common questions

How do you conjugate 울다 in Korean?

울다 (to cry) is 울어요 in the polite 해요체, 웁니다 in formal 합니다체, 울어 in casual 반말 and 운다 in the plain written style. The past is 울었어요.

What is the past tense of 울다?

울었어요 in everyday polite speech, 울었습니다 formally. It is built from the 아/어 form 울어 plus ㅆ, which is why an irregular stem shows its irregularity here.

Is 울다 irregular?

Yes — it is ㄹ dropping (ㄹ 탈락). ㄹ drops before ㄴ, ㅂ and ㅅ: 살다 → 삽니다. Regular, but universal. That is why the stem looks different in 울어 and 우니 but unchanged in 웁니다.

What TOPIK level is 울다?

1급 — TOPIK 1, beginner.
