Korean Negation with 안 an, 못 mot, and 지 ji… 않다 anda

In this post we’ll look at negation in Korean. There are a few different ways to negate verbs and adjectives in Korean, and we’ll cover them here. First, we’ll start with the simplest kind of negation, also known as short negation, with 안 an. Next, we’ll see a second short negation, 못 mot, which specifically refers to ability. After that, we’ll turn to long negation with 지 ji… 않다 anda. Finally, we’ll see some Korean verbs that are inherently negative, one of which is extremely common.

Short Korean Negation with 안 an

First, let’s start with the easiest kind of negation in Korean. To form a short negation, simply put the particle 안 an right before the verb or adjective (which, remember, is a verb in Korean.)

• 커피를 안 마셔요.
  keopi-reul an masheoyo.
  I don’t drink coffee.
• 두부를 안 먹어요.
  dubu-reul an meogeoyo.
  I don’t eat tofu.
• 고기를 안 먹습니다.
  gogi-reul an meogseumnida.
  I don’t eat meat.
• 야구를 안 좋아해요.
  yagu-neun an joahaeyo.
  I don’t like baseball.
• 이 집은 안 커요.
  i jip-eun an keoyo.
  This house is not big.
• 이 집은 안 비싸요.
  i jip-eun an bissayo.
  This house is not expensive.
• 공원에 안 갔어요.
  gongweon-e an gasseoyo.
  I didn’t go to the park.
• 공부 안 했어요.
  gongbu an haesseoyo.
  I didn’t study.

Short Korean Negation with 못 mot

Now let’s look at negation with the particle 못 mot. The negative particle 못 mot functions just like 안 an, but it has a different meaning. Use 못 mot when you’re negating an ability. It’s similar to cannot, not able, or don’t know how to in English.

• 한국어를 못해요. 
  hangugeo-reul mot haeyo.
  I don’t/can’t speak Korean.
• 그 남자는 중국어를 못해요. 
  keu namja-neun junggukeo-reul mot haeyo.
  That man doesn’t/can’t speak Chinese.
• 저는 수영을 못해요.
  jeoneun suyeong-eul mot haeyo.
  I can’t swim. I don’t know how to swim.
• 한국어를 이해 못 해요.
  hangugeo-reul ihae mot haeyo.
  I can’t understand Korean.
• 제가 피아노를 못 쳐요.
  jega pianoreul mot chyeoyo.
  I can’t play piano. I don’t know how to play piano.
• 공부 못 했어요.
  gongbu mot haesseoyo.
  I couldn’t study. I wasn’t able to study.
• 어제 너무 피곤해서 숙제를 못 했어요.
  eoje neomu pigonhaeseo sukjereul mot haesseoyo.
  I was too tired yesterday, so I couldn’t do my homework.

Long Korean Negation with 지 ji… 않다 anda

Next, we’ll turn to long Korean negation. Placing 안 an or 못 mot right before the verb is the easier way to form a negative in Korean. But long negation is just as common. It means the same thing and is almost always interchangeable with short negation. It’s more typical in official or formal language, but not at all limited to it.

Forming Long Negation with the Verb Stem

The shape of a Korean long negative is:

verb stem + suffix –지 –ji + conjugated form of 않다 anda

So, the first thing you need to do is find the verb stem. The verb stem is very easy to form. Simply remove the final –다 –da of the dictionary form, and you’re left with the verb stem. This is what you add –지 –ji to for the long negative.  And finally conjugate the main verb 않다 anda (않아 ana / 않아요 anayo / 않습니다 anseumnida).

Dictionary form	Verb stem	Negative
하다 hada (to do)	하– ha-	하지 않아요 haji anayo
먹다 meokda (to eat)	먹– meok-	먹지 않아요 meokji anayo
마시다 mashida (to drink)	마시– mashi-	마시지 않아요 mashiji anayo
가다 gada (to go)	가– ga-	가지 않아요 gaji anayo
좋아하다 joahada (to like)	좋아하– joaha-	좋아하지 않아요 joahaji anayo

In cases of negation with 못 mot (cannot), you’ll see the same지ji followed by 못하다 (못해 mothae / 못해요 mothaeyo / 못합니다mothamnida).

Dictionary form	Verb stem	Negative
하다 hada (to do)	하– ha-	하지 못해요 haji mot haeyo
가다 gada (to go)	가– ga-	가지 못합니다 gaji mot hamnida)

Korean Negation with Inherently Negative Verbs

Korean has a few verbs that are inherently negative. This means that there’s no need to negate them, because they are already negative.

없다 eopda

By far the most common one is 없다 eopda (없어 eopseo / 없어요 eopseoyo / 없습니다 eopseumnida) which is the negative of 있다 itda (to exist, to be located) (있어 isseo / 있어요 isseoyo / 있습니다 isseumnida). These verbs are most often used for possession and location. (Remember to use the subject particle –이/-가 -i/-ga for the possession.)

• 집이 있어요. / 집이 없어요.
  jip-i isseoyo. / jip-i eopseoyo.
  I have a house. / I don’t have a house.
• 차가 있습니다. / 차가 없습니다.
  cha-ga isseumnida. / cha-ga eopseumnida.
  I have a car. / I don’t have a car.
• 우리는 서울에 있어요. / 우리는 서울에 없어요.
  uri-neun seoul-e isseoyo. / uri-neun seoul-e eobseoyo.
  We are in Seoul. / We aren’t in Seoul.

The past tense forms of 없다 eopda are 없었어 eopseosseo / 없었어요 eopseosseoyo / 없었습니다 eopseosseumnida.

• 차가 없었어요.
  chaga eopseosseoyo.
  They didn’t have a car.

• 학생들은 도서관에 없었습니다.
  hagsaengdeul-eun doseogwan-e eobs-eossseubnida.
  The students weren’t at the library.

Remember to use 없다 eopda when you negate adjectival phrases that use 있다 itda.  

• 국은 맛있어요. / 국은 맛없어요.
  gug-eun mashisseoyo. / gug-eun mateopseoyo.
  The soup is tasty. / The soup isn’t tasty.

  i yeonghwa-neun ingiga isseoyo. / i yeonghwa-neun ingiga eopseoyo.
  This movie is popular. / This movie is not popular.

모르다 moruda

Another important inherently negative verb is 모르다 moruda, which means not know or not realize.
