자주 묻는 질문Common questions

How do you conjugate 발하다 in Korean?

발하다 (to emit, to radiate) is 발하요 in the polite 해요체, 발합니다 in formal 합니다체, 발하 in casual 반말 and 발한다 in the plain written style. The past is 발핬어요.

What is the past tense of 발하다?

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

Is 발하다 a regular verb?

Yes. Its stem never changes shape: 발합니다, 발하, 발하니 all keep 발하 intact. Only the ending moves.

What TOPIK level is 발하다?

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.
