Common questions

How do you conjugate 두렵다 in Korean?

두렵다 (to be fearful, to be scared) is 두려워요 in the polite 해요체, 두렵습니다 in formal 합니다체, 두려워 in casual 반말 and 두렵다 in the plain written style. The past is 두려웠어요.

What is the past tense of 두렵다?

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

Is 두렵다 irregular?

Yes — it is ㅂ irregular (ㅂ 불규칙). ㅂ becomes 우 before a vowel: 춥다 → 추워요. That is why the stem looks different in 두려워 and 두려우니 but unchanged in 두렵습니다.
