Common questions

How do you conjugate 달이다 in Korean?

달이다 (to decoct, boil down) is 달여요 in the polite 해요체, 달입니다 in formal 합니다체, 달여 in casual 반말 and 달인다 in the plain written style. The past is 달였어요.

What is the past tense of 달이다?

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

Is 달이다 a regular verb?

Yes. Its stem never changes shape: 달입니다, 달여, 달이니 all keep 달이 intact. Only the ending moves.

What TOPIK level is 달이다?

It carries no TOPIK grade. That is a fact about the published word lists rather than about the word — it conjugates by exactly the same rules as everything else.
