Explanation

This pattern is added to verbs and adjectives to negate an action or state.

It approximates to 'not' in English.

It is formed by adding 안 to the front of verbs and adjectives or -지 않아요 to the end of verb and adjective stems.

Details

Because verbs that end in 하다 are comprised of 'Noun + 하다', they are negated by adding 안 to the front of the verb, forming 'Noun 안 하다'. Adjectives, on the other hand, are negated by adding 안 to the front, as in '안 + Adjective'. Note, however, that for the verbs 좋아하다 (to like) and 싫어하다 (to dislike), because they are not verbs in the form of 'Noun + 하다', but rather are indivisible, single verbs, they are written as 안 좋아하다/좋아하지 않다 and 안 싫어하다/싫어하지 않다.

Although 안 and -지 않다 can be used in declarative and interrogative sentences, they cannot be used in imperative or propositive sentences.
