Common questions

슬프다 (to be sad) is 슬퍼요 in the polite 해요체, 슬픕니다 in formal 합니다체, 슬퍼 in casual 반말 and 슬프다 in the plain written style. The past is 슬펐어요.

What is the past tense of 슬프다?

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

Is 슬프다 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 슬퍼 and 슬프니 but unchanged in 슬픕니다.
