Negative sentences in Korean are generally made in two ways:

-by prefixing any verb with , and conjugating as normal.

-by removing the 다 from a verb, affixing 지 않다 on the end, and conjugating from the 않다 area, which will become 않아, 않아요 and so on, as with all verbs that have an 아 sound.

  1. 밥을 먹어요 - (I) eat food.
  2. 밥을 안 먹어요 - (I) don't eat food.
  3. 밥을 먹지 않아요 - (I) don't eat food.

  1. 뽀뽀를 해요? - (You) kiss?
  2. 뽀뽀를 안 해요? - (You) don't kiss?
  3. 뽀뽀를 하지 않아요? - (You) don't kiss?

The 지 않다 ending emphasizes the negative a bit stronger than the 안 prefix.
