The Only Guide You Need to Pass TOPIK Test

Best Self-Study Material to Prepare for TOPIK Test

Learning grammar is one of the most difficult things for Korean language learners. On this blog we will try to help you learn Korean grammar in the quickest and easiest way possible. This blog will be helpful for those who are studying Korean language and want to improve their grammar skills.
Today we’ll see how to form sentences with Korean grammar pattern " V/A ~ㄴ/은/는/ㄹ/ 줄 알다/모르다 " with some example sentences.

A/V ~ㄹ/을/ㄴ/은 줄 알다/모르다

The expression -ㄴ/은/는/ㄹ/ 줄 알았다 is used to stating something the speaker was not aware of or did not anticipate.

It is equal to "I thought.." in English.

For Example:

미나 씨가 어제 학교에 왔어요? 결석한 줄 알았어요.
( Did Mina come to school yesterday? I thought she was absent.)

 -ㄴ/은/는/ㄹ/ 줄 몰았다, on the other hand, is used to end a clause stating what the speaker had assumed to be the case; therefore, it expresses the speaker's realization that his or her assumption was incorrect.

It is equal to "I didn't know" in English.

For Example:

미나 씨가 어제 학교에 온 줄 몰았어요.
( I didn't know that Mina came to school yesterday.)

There are three ways to use this grammar pattern :

  • ㄹ/을 with Verbs and adjectives to describe future possibility
  • 는 With Verb in the present tense
  • ㄴ/은 with verbs in past tense and adjectives

Let's see the difference with the following examples : 

1) 친구가 갈 줄 알았어요. (Future possibility)

I thought my friend would go. 

2)친구가 가는 줄 알았어요. (Present tense)

I thought my friend was going. 

3) 친구가 간 줄 알았어요. (Past tense)

I thought my friend was gone.

Rule to conjugate :

In the first case :

V/A ㄹ/을 - to describe future possibility

  • ㄹ is used with the verb and adjectives when the stem ends with a vowel of ㄹ
  • 을 is used with the verb and adjectives when the stem ends with any consonant. 

Example :

1) 그녀가 파티에 오지 않을 줄 알았어요.
I thought she wouldn't come to the party.

2) 장소가 이렇게 넓을 줄 몰랐어요.
I didn't expect the place to be this big.

In the second case :

V 는 with the present tense

  • 는 is used with the verb irrespective of whether the verb stem ends with a consonant or vowel.

Example :

1) 난 그들이 곧장 집에 가는 줄 알았어요.
I think they went straight home.

2) 이렇게 먹는 줄 몰랐어요.
I didn't know you could eat like this.

In the third case :

V/A ㄴ/은 with verb in past tense and adjectives

  • ㄴ is used with the verb and adjectives when the stem ends with the vowel or ㄹ.
  • 은 is used with the verb and adjectives when the stem ends with a consonant.

Example :

1) 작년에 캘리포니아로 이사간 줄 알았어요.
I thought she moved to California last year.

2) 저는 지수가 작년에 결혼한 줄 알았어요.
I thought jisoo got married last year.

  1. 내가 초콜릿을 좋아하는 줄 알았어요.
    I thought you like chocolate.
  2. 그녀는 네가 오는 줄 몰랐어요.
    She didn’t know you were coming.
  3. 내가 오는 줄 알았어요.

  7. 난 네가 기술적인 걸 많이 아는 줄 알았어요.
