Common questions

How do you conjugate 잘다 in Korean?

잘다 (to be small) is 잘아요 in the polite 해요체, 잡니다 in formal 합니다체, 잘아 in casual 반말 and 잘다 in the plain written style. The past is 잘았어요.

What is the past tense of 잘다?

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

Is 잘다 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 잘아 and 자니 but unchanged in 잡니다.

What TOPIK level is 잘다?

6급 — TOPIK 6, mastery.
