How to Say “Can’t” in Korean

Below are the different ways to say “can’t” in Korean, plus some example sentences.

불가능 (bulganeung)

The closest option to the word “can’t” as vocabulary would be 불가능 (bulganeung), which translates to “impossible” or that something cannot be done. However, to learn how to say can’t in Korean, you need to be aware that it is more often expressed as a part of grammar rather than new vocabulary. There are a few grammar patterns with which you can express this, depending on what meaning you are after.

-ㄹ/을 수 없다 (/eul su eopda)

The first grammar pattern with which to say can’t in Korean is -ㄹ/을 수 없다 (-ㄹ/eul su eopda). For example, if you combine it with the verb 가다 (gada), which means ‘to go’, you get 갈 수 없다 (gal su eopda), which translates to ‘can’t go’. Of course, you will need add more to the sentence for it to make sense.

Example:

1. 미안하지만 오늘 만날 수 없어요. (mianhajiman oneul mannal su eopseoyo.)

I’m sorry but I cannot meet today.

2. 더 이상 그 남자의 말을 믿을 수 없어서 헤어졌어. (deo isang geu namjaui mareul mideul su eopseoseo heeojyeosseo.)

I could no longer believe in his words so I broke up with him.

-ㄹ 줄 모르다 (-jul moreuda)

The second option to use is -ㄹ 줄 모르다 (- ㄹ jul moreuda). This is the structure you can use to express that you do not know how to do something, for example if you do not know how to cook.

1. 저는 아직 스페인어를 하나도 할 줄 몰라요(jeoneun ajik seupeineoreul hanado hal jul mollayo.)

I cannot speak any Spanish yet.

-면 안되다 (-myeon andoeda)

The third one is -면 안되다 (- myeon andoeda). This one you will use when you want to say that someone is not allowed to do something.

1. 오늘 술 마시면 안돼. → (oneul sul masimyeon andwae.)

We can’t drink today.

못하다 (mothada)

Another option in some cases is 못하다 (mothada). This is similar to -ㄹ 줄 모르다 (- ㄹ jul moreuda), although it is often used together with the word 잘 (jal) to indicate that one is not good at something rather than that one doesn’t at all know how to do something.
