-잖아

You Know, ... Right?

Level 3Sounds Like jana

-잖아 is a sentence ending used to confirm or remind the listener of something that both the speaker and listener already know. It's similar to saying "..., you know?", "As you know,...", or "Come on,..." in English.

How It Works

-잖아 is a very common ending in conversational Korean. Its primary function is to build rapport by referencing shared knowledge. However, its nuance can change significantly with tone.

Common Usage Scenarios:

  • Stating an obvious fact: When something is plain to see or common knowledge.
    Example: 오늘 날씨가 정말 춥잖아. (The weather is really cold today, isn't it?)

  • Reminding someone of something: When the listener seems to have forgotten a piece of information.
    Example: 우리 7시에 만나기로 했잖아. (We agreed to meet at 7, remember?)

  • Giving a known reason: When explaining why something is the case, using a reason the listener is already aware of.
    Example: A: 왜 파티에 안 가? (Why aren't you going to the party?) B: 내일 시험 있잖아. (I have an exam tomorrow, you know.)

  • Expressing mild frustration or insistence: When you have to repeat something that should be obvious.
    Example: 내가 하지 말라고 몇 번이나 말했잖아! (I told you so many times not to do it!)

Comparison with -지?:
Both endings can seek confirmation, but they have a key difference.
• -지? is more of a genuine question seeking agreement. The speaker is less certain and is checking with the listener. (e.g., 날씨 좋지? - The weather's nice, right?).
• -잖아 is more of a statement asserting shared knowledge. The speaker is confident the listener already knows. (e.g., 날씨 좋잖아. - The weather's nice, as you know.).

  1. 걱정 마세요. 시간 아직 많잖아.

    Don't worry. We still have plenty of time, you know.

    Word by Word: Worry don't. Time still much-잖아.

    The speaker is reassuring the listener by pointing out an obvious fact: that there is a lot of time left.

  2. 어제 내가 너한테 전화했잖아. 왜 안 받았어?

    I called you yesterday, you know. Why didn't you answer?

    Word by Word: Yesterday I to you called-잖아. Why not received?

    The speaker is reminding the listener of a past event (the phone call) that the listener should be aware of.

  3. 이 식당은 항상 사람이 많잖아. 우리 다른 데 가자.

    This restaurant is always crowded, as you know. Let's go somewhere else.

    Word by Word: This restaurant always people are many-잖아. We different place let's go.

  4. 에이, 거짓말 아니잖아. 너도 봤잖아.

    Come on, it's not a lie. You saw it too.

    Word by Word: Hey, lie is not-잖아. You also saw-잖아.

    Here, -잖아 is used twice to strongly assert facts that the listener is aware of, expressing a bit of insistence.

Common Mistakes

  • Using -잖아 for new information the listener doesn't know.

    Not Quite처음 뵙겠습니다. 저는 김민준이잖아.
    Better처음 뵙겠습니다. 저는 김민준입니다.

    -잖아 implies shared knowledge. When introducing yourself for the first time, the listener doesn't know your name, so using -잖아 is unnatural and confusing. Use a standard introduction like 입니다 or 이에요/예요.

  • Overusing -잖아, which can make you sound argumentative or condescending.

    Different MeaningA: 이 영화 재미없어. B: 아니, 재미있잖아. 배우도 유명하잖아. 너도 재미있다고 했잖아.
    BetterA: 이 영화 재미없어. B: 그래? 나는 재미있는데. 배우도 유명하고. 너도 전에 재미있다고 하지 않았어?

    Using -잖아 repeatedly in a disagreement can sound like you are scolding or talking down to the other person. It's better to state your opinion with -는데 and ask a question with -지 않았어? for a softer, more conversational tone.
