Korean adjectives are used at the end of a clause or sentence and conjugated like verbs.
The noun modifiers, -은/ㄴare added to adjectives and are always placed before the noun.
1. If the adjective ends in a vowel, -ㄴ is added to the stem, while -은 is added if the adjective ends in a consonant.

예쁘다 : 예쁜 -ㄴ → 예쁜 꽃(a pretty flower)
2. -는 is used after -있다, -없다 and compound words like 재미있다, 맛있다.
맛있다 : 맛있 -는 → 맛있는 음식(delicious food)
재미없다 : 재미없 -는 → 재미없는 사람(an uninteresting person)
