In this lesson, we look at how to say “I guess …”, “I assume …” or “I suppose …” in Korean : -나 보다 [-na bo-da] Today’s key structure is somewhat similar to -것 같다 in meaning, but it has a stronger nuance of “I assume … based on this fact” or “I suppose … because …”. We hope you enjoy this lesson and thank you as always for studying Korean with us!

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.

    For situations where you go somewhere with a friend but you have no money and it’s time to pay for ~~~ and they look at you for money can you say:
    저는 고장났어요. I’m broke.
    돈 있었나 봤어요. I assumed you had money.

    오늘 아침에 눈이 내렸나 봐요!

    “눈이 오다”도 괜찮아요?

    오늘 아침에 눈이 내렸”다” 봐요! 는 어때요?

    • Greg

      You mean 내렸다고 봐요 – yes it also means “I think”
      About 오다 maybe 눈이 오고 있었나 봐요

  • ichinii

    i heard a song titled “바라보나봐”
    i quite confusing because when i see the English translation
    the word mean is “just look at you”??
    is “바라보나봐” using verb ending 나 보다?
    and what is actually the meaning of “바라보나봐”?

    thanks

    지금은 집에 아무도 없나 봐요. (I guess there is nobody at home now.)

    제 오빠가 집에 아직 안 왔는데, 데이트 갔나 봐요. (My brother hasn’t come home yet, I guess he went dating.)

    그 거짓말을 벌써 알았나 봐요. (I guess they already knew the lie.)

    비가 올 것 같아요. 여기에 안 오나 봐요. (I think it will rain. I guess they won’t come here.)

    부산에 집이 샀나 봐요. (I guess they bought the house in Busan.)

    감사합니다! :)

  • Tim Cheng

    엄마가 오나 봐요.

    이 햄버거가 맛있나 봐요.

  • dong xian

    Would it make sense to say
    연습하고 있었나 봐요…??

    Also, I have a question.. Do Korean people ever use the was/were doing past continuous tense 고 있었다? Considering the fact they rarely use the present continuous 고 있다 and just use plain present tense… also, does the past continuous tense have the same connotation as it does in English??
    like “I did my homework (and completed the action)” as opposed to “I was doing my homework (but then i stopped because the phone rang or something)”??

  • Nicky

    안녕하세요!

    I have a question. Would it make sense to to combine this lesson with Level 2 Lesson 20 to say:
    시작해야 되나 봐요 – I guess I should start / it seems like I should start …?

    감사합니다!

  • Dolsanria

    민정 씨는 저를 너무 미워하나 봐요.

    Is this right? 감사합니다!
