멋있다 — to be cool

to be cool

Explanation

멋있다 means “to be cool.” This page gives the polite conversation set: present, past, future, progressive, desire (-고 싶어요), and a please form — not only the bare dictionary 다 form.

Conjugation notes for 멋있다: Auto polite pattern with 아/어 harmony — verify irregulars (ㄷ/ㅂ/르/ㅅ/ㅎ/으) against a native reference. Prefer curated tables when listed on the conjugator hub.

Put 멋있다 in real frames with time (지금/어제/내일), place (학교/집/카페), and object particles when needed. Charts without sentences do not stick.

Drill path: say 멋있어요 three times → full sentence with 지금 → switch to 멋있었어요 with 어제 → 멋있을 거예요 with 내일. Then open the interactive conjugator for any hesitation.

Next step: link a vocabulary leaf, a grammar ending page (-아요/어요, -고 있다), and keep speech levels consistent across the sentence.
