자주 묻는 질문Common questions

How do you conjugate 주시하다 in Korean?

주시하다 (to watch closely) is 주시하요 in the polite 해요체, 주시합니다 in formal 합니다체, 주시하 in casual 반말 and 주시한다 in the plain written style. The past is 주시핬어요.

What is the past tense of 주시하다?

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

Is 주시하다 a regular verb?

Yes. Its stem never changes shape: 주시합니다, 주시하, 주시하니 all keep 주시하 intact. Only the ending moves.

What TOPIK level is 주시하다?

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.
