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”.



Thank you so much for studying with us and as usual, be sure to leave us comments and practice making your own sample sentences!

You can view a free PDF for this lesson here, or if you want to study with our TalkToMeInKorean textbooks, you can get them here. And after you learn the basics, try writing your own Korean sentences and get corrections from native speakers through HaruKorean, our 1:1 correction service.

    안녕하세요~

    Just wanted to say first that this site is really great. There are a lot of grammar aids on the internet but most lack in comparison to this….a very complete and yet still-growing resource made by people who really care about others learning the language. Thank you for providing all of this!

    But as for my question…I’ve actually been wondering about this for a while now. I’ve heard this construction before and pretty much understand it. But something that confuses me is that, in order to express a (seemingly?) similar question, a different construction was used. Something like:

    내가 누구를 사랑하는것을 알아요?

    Or at least it was something along those lines. Could it be something like, if you use the 는지 construction, you are portraying a more “whether or not/if” kind of expression (Do you know whether or not…), vs. if you use 는것을 it’s just “do you know THAT blahblah)?? Maybe I’m just remembering totally wrong, but I’m pretty sure I was told there is another way to say this type of thing using a construction other than -는/ㄴ 지.

    Thanks!

      똑앝은 준제가 있었어요!

      From my understanding when you add 는것은/는것이 after a verb, its more like saying “the act of”.

      ie, 먹는것을 좋아해요. i like the act of eating
      or 한국 공부하는것이 힘들어요. the act of studying korean is hard

      It would be great if a pro could provide some more tips on what the difference here is!

      감사합니다!

    무슨 책 읽는지 중요하지 않아요. It doesn’t matter what book you read.
    얼마 동안 일하는지 중요하지 않아요. It doesn’t matter how long you work.
    어떻게 해야 하는지는 뻔하죠. It’s obvious what you should do.
    그 모자가 얼마나 하는지 그에게 물어보아라. Ask him how much the hat is.
    어떻게 하는지 보여드릴게요. I’ll show you how to do it.

  11. Chris says:

    Can someone please tell me how to say “if” in this pattern? Like “Could you tell me if this book is interesting?” I’m wondering how to say this because saying “이 책이 재미있는지 말해주세요” means “Please tell me this book is interesting” and that’s not what i mean. Thank you :D

    • 스티븐 says:

      이 책이 재미있으면 말해주세요.

      IF this book is interesting, please tell me

    Hello,
    I have a question…
    What is the difference between 몰라요 and 모르겠어요 to mean ‘I don’t know’?
    Thank-you

  17. Peter Pockets says:

    I think in most of the example sentences of the lesson “neun-ji” = a comma separating two clauses in a compound-sentence; rather than “if”.
