    숙제를 해야 돼요.

  • Farzam Habib Khan

    저는 한국어를 배우해야 돼요…그런데 지금 자야 돼요 왜냐하면 엄마가 화가난다 …

  • Xin Ru

    My sample sentences:

    내일 여행을 갈 거예요. 그래서 오늘 가방을 싸야 돼요.
    I’m going to go travelling tomorrow. Therefore, I have to pack my bag today.

    저는 한국어를 잘 못 해요. 저는 노력해야 돼요.
    I am not good at Korean. I have to try hard.

  • McKenzie Rodwell

    오늘 공부하야 돼요. = I have to study today.
    언제 뭐 한국에 와야 돼요? = what should I do when I come to Korea?


    • nin

      I’m by no means a teacher, I’m just learning too, but I think your second one should be like:
      한국에 도착할 때 (structure they didn’t teach yet), 뭐 해야 될 거예요?
      What should I do when I arrive in Korea?
      Please someone correct me if I’m wrong.

    • McKenzie Rodwell

      thank you for your help i really appreciate it. i just have a quick question what does 도착할 때 mean i know its arrive but why is it write like that. once again thank you very much for your help.

    • nin

      The ~ㄹ/을 때 structure with a verb means “when I (verb)…”, so in this case 도착할때 (when I arrive). Another example: 영화를 볼 때 말 안 해요. (When I watch a movie, don’t speak). Did you understand? If not, you can check this website http://www.howtostudykorean.com/unit-2-lower-intermediate-korean-grammar/unit-2-lessons-42-50/lesson-42/ but in my experience it’s better to focus on only one resource kkkkk I’ve been studying Korean for around three to four years, but I never stuck with only one so I got overwhelmed and didn’t develop a lot. That’s just me being noisy, please do as you like. I think we’ll learn this structure soon, though. I hope I helped! Merry Christmas ^^

    • McKenzie Rodwell

      Thank you so much and I understand now. and yeah same with me and Spanish, studied Spanish for like 10 years in school and all I can say is hello, how are you doing, eat and, drink ㅋㅋㅋㅋ so many different ways i was taught hard for the information to stick but Im going to try to learn again someday. Merry Christmas and a Happy New Year to you as well. 🙂

    • bardalas142

      You don’t always have to include the subject though, in this case it’s clear it’s you.

  • Zianthropy1

    안녕하세요! I am a little confused about the use of 되 and 돼. In your grammar pattern, you used 되다. However, all your sample sentences showed the use of 돼요. Kindly clarify. 너무감사합니다!

    • troy

      The grammar patterns use the base form (되다) because it is where all
      other conjugations are derived. 돼요 is just one of those conjugations and
      one that is commonly used in speech.

  • aithusae

    안녕하세요, 지금 많이 헌국어 단어를 복습해요. 그리고 자야 돼요. 내일의 수업은 7:30시 시작할 거예요.

  • bardalas142

    올 여름에 대학 입학 시험을 통과해야 한다 때문에 제가 다음 2달 동안 열심히 공부해야 됍니다.

  • 민지

    저는 자고 싶어요, 그렇지만 공부어야 돼요.. = I want to sleep, but I have to study.
    저는 이거 인쇄어야 돼요. = I have to print this.
    너 이제 가야 돼? = Do you have to go now? (반말)

  • Châu Lê

    공부해야 돼지만 지금 자고 너무 너무 싶어용~ ㅠㅠ

    • Châu Lê

      Pls tell me what’s wrong with my sentence if u find any~ thank you ❤

  • Kae

    저는 한국어랑 TTMIK 공부해야 돼요 = I have to study korean with TTMIK
    I don’t know if the sentence is correct at all. Please, if anyone notices that something is wrong, tell me ^^ Thanks 🙂

    • A.L.

      “랑” is a little bit misplaced here.

      “한국어랑 TTMIK 공부해야 돼요” in English would be, “I have to study Korean and TTMIK”.

      You can say “저는 TTMIK랑 한국어를 공부해야 돼요” if you want to imply that you have to study Korean with the TTMIK community (because it’ll translate to “I and TTMIK have to study Korean”), but if you want to say that you have to study Korean *at* TTMIK you’re better off saying “저는 TTMIK에서 한국어를 공부해야 돼요”.

      If you want to say that you’re studying with the help of TTMIK as a tool, you’ll probably have to use a different particle – I’m sorry, I don’t know which one that is yet.

    • Kae

      What I try to say is that I have to study Korean WITH TTMIK. Thank you so much for your correction!!!! ^^

  • 민지

    Thank you, made a little typo there ㅋㅋ

  • A.L.

    우리 집에서 닭을 없어요 그레서 되지갈비만 먹어야 할 거예요. (<— can you conjugate 해요 to future tense here?)

  • Jixanh

    저는 베트남어도 공부해야 돼요. (I have to study Vietnamese, too (besides Korean).)
    내일 운동해야 돼요. (I have to exercise tomorrow.)
    올해 더 열심해야 돼요. (I have to work harder this year.)

  • 이상민

    Whats the difference between ‘되’ and ‘돼” ? Thank you! 🙂
