Level 2 Lesson 2 / object marking particles / 을, 를

Download Available

안녕하세요. ^^ In this lesson, we are looking at the object marking particles. As we mentioned a few times through our previous lessons, there are different types of particles in Korean, and these particles (subject marking particles, topic marking particles, location marking particles, and so on) are what make it easy to understand Korean sentences, even when the word order changes.
If you have any questions, please feel free, as always, to leave us a comment! 감사합니다.

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.

    이 수업는 좋아해요. 수업이 조사를 이해해 유용해요. 하지만, 다려요. 저는 다시 공부할 거예요.

    What I attempted to say above:
    “This is a good lesson [topic – first time mentioning lesson]. This lesson [subject – also emphasis of “in particular”] is very useful for understanding particles [object]. However, it is a difficult lesson [implied]. I [comparison – as compared to other learners] will have to review the lesson [implied] again.”

    I don’t think it is correct, but I can’t figure out how to write “for understanding…”. So I just wrote the present tense.

    감사합니다 for the lesson!

      이 수업 좋아요. 조사를 이해하는 데 유용해요. 하지만 어려워요. 저는 다시 공부할 거예요.

    • Matt

      Does VERB STEM + 는/은 데 work for all verbs?

      Ex. 영어를 읽은 데 어려워요. = It is hard to read English. / Reading English is hard.

      Is there a future lesson I could review on this topic?


    • Seokjin Jin

      In that case, we normally say “영어를 읽는 것이 어려워요”.

    thanks for a very useful lesson!!!

  • Kiri

    Thank you so much!

    • Seokjin Jin

      You’re welcome! Thanks for your comment. :)

  • Filip


    I don’t get why 이다 is used in the following sentence: 화장실 어디예요.
    I thought it should be 있다.

    Thank you in advance.

    • Seokjin Jin

      어디 means “where” so we can find out this sentence is a question.

      In question form, -이다 is conjugated to -이에요? and -있다 is conjugated to -있어요?

      When you want to ask where the bathroom is, you can say “화장실 어디예요? or 화장실 어디에 있어요?”.

  • Jean Pauline

    Thank you so much :) this is really helpful

  • Liisu//

    that makes sense ! i finally managed to understand the particles & how to use them! <3

    감사합니다 !

  • Liisu//

    does that ‘When do you need to use object marking particles?’ explanation work with other particles too ?
    btw, it’s really helpful, at least i’ve got to know more about using particles ! ^^
    감사합니다 !

    안녕하세요! 삼겹살을 한달에 몇 번 먹어요?
    Is this how to say “How many times a month do you eat 3 layers meat?”

    • JooyeonPark

      네 맞아요!
      yes, you are right! :)

    • Gavin

      Thank you for your time!

  • Nandini

    이 영화 몇 번 봤어요?

  • Leela

    물을 여덟 잔 날로 마셔요.

  • Christie

    축구를일주일에몇반왔어오? I want to ask someone in my club how many times a week they come to play soccer! Thanks!

    • JooyeonPark

      You can ask him/her “축구하러 일주일에 몇 번 와요?”

    • Cee

      Hello ^_^ I have a question about the sentence that you demonstrated and I was wondering, um, why 일주일에 and not 일주에? Why is there two 일 for the former? Wouldn’t the latter be sufficient to mean ‘one week’?

  • Kaye Razelle

    우유를 마시거시퍼요 is this right? :P

    • 3737

      Not 마시거시퍼요, 마시고 싶어요! So 우유를 마시고 싶어요 is the right one :9

  • nadzmi

    I am just doing fine throughout all lessons except chapters relating to particles (except location marking particle) like topic, subject, and object marking particles. Can I have a list of other sentence examples and things that distinguish them ? I’ll be very glad if you can email me. 너무 감사합니다 !

  • Chiara Copeland

    Are particles similar to the case system in russian and German? Do you have to use them all the time?

    Questions, questions, questions.. I’m hoping that someone will come to find this comment and answer T_T

    나는 사과 먹었어요
    Using that ‘는’ in the sentence..

    1. Am I implying that other than other foods, I only ate apple?
    2. or Am I just emphasizing the ‘사과 먹었어요’? Which can be an answer to the question, “What did you eat?” = “나는 사과 먹었어요.”

    나가 사과 먹었어요. -> 내가 사과 먹었어요.
    Using that 가 in the sentence

    1. Am I answering the question, “Who ate the apple?” = “내가 사과 먹었어요”

    I’m still confused, sorry.

    Is the “는/은” an answer to a “WHAT” question?
    “What did you eat yesterday?”
    “나는 사과 먹었어요.”

    Is the 이/가 an answer to a “WHO” question?
    “Who ate the apple?”
    “내가 사과 먹었어요”

    • Justyna Rozwarska

      “나는 사과 먹었어요” (I ate an apple)
      you are emphasizing that YOU, no one else, but you ate an apple.

      If you want to imply that out of the whole existing food, you ate only an apple it’ll be:
      “사과는 먹었어요”
      (you don’t need to add “나”, it’s unnecessary, because it’s an answer to question “What did you ate?” and everyone knows that it’s about you, it’ll be unnatural with “나”).

      I think that in the sentence:
      “내가 사과 먹었어요”
      “가” is just to emphesize that I ate an apple, but not that strong as “는” …. I’m a little bit confused in this too, but I was looking for an anwser and “이/가” doesn’t change the meaning of sentence as “는” from what I’ve seen.
      “(…)with 이 and 가, you can add more flavor and more concrete meanings to your Korean sentences
      when you want to emphasize WHO did something, WHICH ONE is good, and etc.” (from TTMIK lesson)
      And yes, this is an aswer to question “Who ate the apple?” (Just like for “나는 사과 먹었어요”, you can use both).

      I know that you asked this question a month ago, but I hope that it’ll help you anyway ^^
