자주 묻는 질문Common questions

How do you conjugate 졸다 in Korean?

졸다 (to doze off) is 졸아요 in the polite 해요체, 좁니다 in formal 합니다체, 졸아 in casual 반말 and 존다 in the plain written style. The past is 졸았어요.

What is the past tense of 졸다?

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

Is 졸다 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 졸아 and 조니 but unchanged in 좁니다.

What TOPIK level is 졸다?

2급 — TOPIK 2, elementary.
