Common questions

How do you conjugate 떨다 in Korean?

떨다 (to tremble) is 떨어요 in the polite 해요체, 떱니다 in formal 합니다체, 떨어 in casual 반말 and 떤다 in the plain written style. The past is 떨었어요.

What is the past tense of 떨다?

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

Is 떨다 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 떨어 and 떠니 but unchanged in 떱니다.

What TOPIK level is 떨다?

3급 — TOPIK 3, lower intermediate.
