Whether or not / -(으)ㄴ/는지

안녕하세요. ^^ In this lesson, we take a look at the verb ending -(으)ㄴ/는지. It is basically used with verbs related to knowing, guessing, informing, thinking, etc, for expressing the meaning “whether or not”.

The verb ending -(으)ㄴ/는지 is used with verbs related to knowing, guessing, informing, thinking, etc., to express the meaning “whether” or “if”. 


It can also be used with words such as 누구 (who), 어디 (where), 어떻게 (how), 왜 (why), 언제 (when), 뭐 (what) and 얼마나 (how + adverb/adjective) to mark the end of a question inside a compound sentence. 


Conjugation: 

(1) Action verbs 

- Verb stem + -는지 

Ex) 

먹다 → 먹는지 *먹는지 is pronounced as 멍는지.

사다 → 사는지 


- When the verb stem ends with ㄹ, drop the ㄹ and add -는지 

Ex) 

놀다 → 노는지 

풀다 → 푸는지 


(2) Descriptive verbs 

- Verb stems ending with a vowel + -ㄴ지 

(The verb -이다 (to be) is included in this category.)

Ex) 

크다 → 큰지 

예쁘다 → 예쁜지 


- Verb stems ending with a consonant + -은지 

Ex) 

작다 → 작은지 

좁다 → 좁은지 


Take a look at some examples.

(1) 

이거 뭐예요? (= What is this?) + 알아요? (= Do you know) 

→ Do you know what this is? = 이거 뭔지 알아요? 


이거 뭐이다 → 이거 뭐이 + -ㄴ지 → 이거 뭐인지 → 이거 뭔지 → 이거 뭔지 알아요? 

* 인지 is often shortened to -ㄴ지.


(2) 

뭐가 좋아요? (= What is good?) + 몰라요. (= I don’t know.) 

→ I don’t know which one is good. = 뭐가 좋은지 몰라요. 


뭐가 좋다 → 뭐가 좋 + -은지 → 뭐가 좋은지 → 뭐가 좋은지 몰라요. 


(3) 

문제가 있다 (= There is a problem.) + 물어보세요. (= Ask.)

→ Ask (them) if there is a problem. = 문제가 있는지 물어보세요. 


문제가 있다 → 문제가 있 + -는지 → 문제가 있는지 → 문제가 있는지 물어보세요. 



This ending -(으)ㄴ/는지 often implies "whether or not", but "or not" is left unsaid. Here are a few ways to specifically add "or not" in Korean:


(1) 

When the verb is -이다, use 아닌지.

Ex) 

이 금이 진짜 금인지 알고 싶어요. = I would like to know if this gold is real gold.

= 이 금이 진짜 금인지 아닌지 알고 싶어요. = I would like to know whether or not this gold is real gold.


(2) When the verb is 있다, use 없는지.

Ex) 

안에 사람이 있는지 모르겠어요. = I can’t tell if someone is inside.

= 안에 사람이 있는지 없는지 모르겠어요. = I can’t tell whether or not someone is inside.


(3) When the verb is not 이다 or 있다, you can either use 안 -(으)ㄴ/는지 or the antonym of the verb.

Ex)

답이 맞는지 확인해 보세요. = Check if the answer is correct.

= 답이 맞는지 안 맞는지 확인해 보세요. = Check whether or not the answer is correct.

= 답이 맞는지 틀리는지 확인해 보세요. = Check whether the answer is correct or incorrect.


Sample Sentences 

이 사람 누군지 알아요? 

= Do you know who this person is? 


이거 괜찮은지 봐 주세요. 

= See if this is okay.


어떤 메뉴가 인기가 많은지 알려 주세요. 

= Let me know which item on the menu is popular, please.


제가 왜 걱정하는지 몰라요? 

= Do you not know why I worry?


내일 우리 만날 수 있는지 없는지 알고 싶어요. 

= I would like to know whether or not we can meet tomorrow.
