Common questions

How do you conjugate 굴다 in Korean?

굴다 (to behave, to act) is 굴어요 in the polite 해요체, 굽니다 in formal 합니다체, 굴어 in casual 반말 and 군다 in the plain written style. The past is 굴었어요.

What is the past tense of 굴다?

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

Is 굴다 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 굴어 and 구니 but unchanged in 굽니다.

What TOPIK level is 굴다?

6급 — TOPIK 6, mastery.
