안녕하세요! We are learning another great sentence pattern to know in this lesson! Listen in and find out how to say that you “have to” do something or something “should” be done. And after listening to the lesson and checking out the PDF, let us know what you have to do, in Korean!

여러분, 뭐 해야 돼요? What do you have to do?

You can download 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.

    안녕! how does 되다 become 돼요 (present tense)? are there past tense and future tense forms for 되다 as well?

  • Francesco Colléter

    옴마 칩의 잇써 요, 글앳서, 저 는 요 리 안 해더 좨 요

  • Alex

    뭐 사야 해요? and 뭐 사야 돼요? means the same thing?

    • Ashley Heil

      I think it means the same thing but 뭐 사야 돼요 is more common and more used in informal situations

  • 이만

  • Ahmed

    자야 돼요 I have to sleep
    I was wondering how to use -아/어/여야 되다/하다 in past and future tenses.
    Will it be correct if I say:
    자야 될 거예요 I will have to sleep
    자야 됐어요 I had to sleep

    or is there a different way? Thanks :)

  • 아란자

    한국어를 더 공부해야 돼요 means “I should study korean more”, right? 감사합니다!

    저는 빨래 해야 되요. 그리고 자야 해요 – 5시 아침에 예요! 공부 밤새 안 했어요, 놀고 있었어요. 하지만 많이 배우고 있어요!

    • KyungHwa Sun

      Correction :
      해야 되요 –> 해야 돼요
      5시 아침에 예요! –> 아침 5시예요!

    What’s the difference between 자야 하다 and 자야 한다?

    • KyungHwa Sun

      Hello Jasmyne,

      “자야 하다” is “자다 + -아/어/여야 하다,” and it means “to have to sleep,” whereas “자야 한다” is “자다 + -ㄴ- + -아/어/여야 하다.”

      “-ㄴ-” is used in 4 different situations.
      1. when you state a simple fact
      2. when you state a repeated/habitual action
      3. when you state a current situation
      4. when you state a definite future

    오늘 저는 의사선생님한테 가야돼요.

  • Holger

    오늘 저는 사과해야돼요. (Today, I have to apologize.)

  • Diana Artunduaga Osorio

    저는 운동어야 돼요.

    Is it correct? :)

    • KyungHwa Sun

      Correction : 저는 운동해야 돼요.

  • Guest

    저는 운동야 돼요.

    • Elise

      저는 운동해야 돼요. 운동하다 is the verb form. 운동 itself is a noun.

  • Diana Artunduaga Osorio

    저는 운동아야 돼요.

    Is it correct?

    • B. Alvn

      no. 운동해야 is correct…운동하다 is a verb, 운동 is a noun.

    하국어 공부해야 돼요.

    어제 저는 친구랑같이 영화 보고 싶었어요. 그런데 8시 반까지 일해야 됐어요.

    I really like this site and I’m thinking of study Korean in college, but I think it’s very difficult to remember every verb-ending with the different sentence structures.

    Maybe you could put some more grammar practise on your site like your workbook, but then with some more exercises so we could practise our writing ability.

    But nevertheless, your site is very useful!

    I kind of understand some things when someone on tv speaks korean, but I would like to improve it before my college Korean, so that I can have an advantage.

    So keep going!

    (But can you think of putting more practise material for writing or listening skills on the site?)

  • Soo na

    때문에 그 집을 너무 아름다워, 내가 사야 되요

  • Quan Vu

    As far as i can understand, the sentence take 02 meanings: “Until when should I be here?” Or “Until when should YOU be here?”

    Is that right?

    3.언제까지 여기에 있어야 돼요? [eon-je-kka-ji yeo-gi-e i-sseo-ya dwae-yo?]
    = Until when should I be here?

    Tell me in actual conversations that when sentence shall be understood with “I” and when is understood with ” YOU” as the above case ?

    I always feel confused about the meaning of sentences ” subject” is omitted at the beginning of sentence.

  • Angel

    너무 늦었니까 자야 돼요…
    내일은 더 열심해 공부하고 운동해야 되다!

    thanks for the lessons!

  • Matt

    저는 졸려요. 침대에 가야 돼요. = I’m sleepy, I should go to bed.

    In English, “have to” and “must” have more urgency than “should”. For example “I have to go to bed.” means that you are so tired that you can’t stay awake. While “I should go to bed.” suggests that your tired but that there is something you want to stay awake for (perhaps your favorite show is on). Which is the case for -아/어/여 -야 되다/하다?

    감사합니다 for the lesson!
