Grammar note (ㅂ irregular (adj)): ㅂ-irregular adjectives follow the same rule as ㅂ-irregular verbs: the ㅂ changes to 우 when a vowel suffix follows. 덥다 (to be hot) becomes 더워요; 쉽다 (to be easy) becomes 쉬워요. The ㅂ is kept intact before consonant suffixes: 덥고, 쉽지. See all ㅂ-irregular verbs →

Example sentences

How it’s used

춥다 is for cold weather and for feeling cold yourself: 저 추워요 (“I’m cold”). It is ㅂ-irregular: 추워요, 추웠어요, 추운 날씨, but 춥고, 춥습니다. Because it is an adjective, its -(으)세요 form is an honorific statement or question (안 추우세요?), not a command.

Common mistake

Using 춥다 for cold things: ✗ 커피가 추워요 → ✓ 커피가 차가워요. Objects and food are 차갑다; if something hot has gone cold, say 식었어요.
