Common questions

How do you conjugate 불순하다 in Korean?

불순하다 (impure, adulterated) is 불순해요 in the polite 해요체, 불순합니다 in formal 합니다체, 불순해 in casual 반말 and 불순하다 in the plain written style. The past is 불순했어요.

What is the past tense of 불순하다?

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

Is 불순하다 irregular?

Yes — it is 여 irregular (여 불규칙). 하다 and every verb built on it: 하다 → 하여 → 해요. That is why the stem looks different in 불순하여 and 불순하니 but unchanged in 불순합니다.

What TOPIK level is 불순하다?

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.
