How do you conjugate 나쁘다 in Korean?

나쁘다 (to be bad) is 나빠요 in the polite 해요체, 나쁩니다 in formal 합니다체, 나빠 in casual 반말 and 나쁘다 in the plain written style. The past is 나빴어요.

What is the past tense of 나쁘다?

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

Is 나쁘다 irregular?

Yes — it is 으 irregular (으 불규칙). The stem 으 drops before a vowel ending: 쓰다 → 써요. That is why the stem looks different in 나빠 and 나쁘니 but unchanged in 나쁩니다.
