Five basic verbs — 있다, 없다, 가다, 오다, 하다

These are five common Korean verbs. Learn 있다 ↔ 없다 and 가다 ↔ 오다 as opposite pairs. 하다 also joins with many nouns to make verbs.

01있다itda🔊 [읻따]

to exist, to have · to be in a place. It also shows that you own or hold something.

Note English uses two forms: there is and to have. Korean uses 있다 for both. The thing that exists, or that you have, takes 이/가, not 을/를.

Examples 시간이 있다 (to have time) · 집에 있다 (to be at home)

오늘 시간이 있어요? Do you have time today?  |  오늘 = today  |  You can use this question when you make plans

02없다eopda🔊 [업따]

to not exist, to not have · used when something is not there, or when someone does not have it. The opposite is 있다.

Note 없다 is one word. You do not make it by adding a not word to 있다. This one word covers both there is not and does not have.

Examples 돈이 없다 (to have no money) · 문제가 없다 (there's no problem)

오늘은 약속이 없어요. I have no plans today.  |  약속 = appointment, plans  |  없다 takes 이/가, just like 있다

03가다gada

to go · to move away from where you are.

Forms 가요 · 갑니다 · 갔어요 (past)

Examples 학교에 가다 (to go to school) · 집으로 가다 (to go home)

저는 학교에 가요. I'm going to school.  |  The place you are going to takes 에  |  으로 can show the direction you move in

04오다oda

to come · to move toward where you are.

Forms 와요 · 옵니다 · 왔어요 (past)

Note Korean uses 오다 with rain and snow: 비가 와요 and 눈이 와요. English uses It is raining or It is snowing.

Examples 친구가 오다 (a friend comes) · 비가 오다 (it rains)

친구가 우리 집에 왔어요. A friend came to my house.  |  우리 집 = my house, literally our house  |  The polite form is 와요, not 오아요
