What does 就 jiù mean?

「就 jiù」is a very common Chinese word. It can be hard to translate because its meaning changes depending on the sentence.

For beginners, you can first remember these common meanings:

  • soon / right away: 馬上就、立刻就
  • already / as early as: 以前就、早就
  • then / in that case: 如果……就、只要……就、既然……就
  • exactly / precisely: 就是
  • only / just: 就、就只、就只有
  • regarding / based on: 就這個主題來討論

「就」often helps show that something happens quickly, naturally, exactly, or as a result of a condition.

1. 馬上就 / 立刻就: right away

Use「就」with words like「馬上」or「立刻」to show that something will happen soon or immediately.

Pattern Meaning
馬上 / 立刻 + 就 + Verb will do something right away
Chinese Pinyin English
我馬上就走。 wǒ mǎshàng jiù zǒu I will leave right away.
我立刻就去。 wǒ lìkè jiù qù I will go immediately.
他現在就要走。 tā xiànzài jiù yào zǒu He is leaving right now.

Without「就」, the sentence can still be correct, but「就」makes the timing feel more immediate.

2. Action 1 + 後,就 + Action 2

Use「就」to show that one action happens right after another action.

Pattern Meaning
Action 1 + 後,就 + Action 2 after action 1, action 2 happens right away
Chinese Pinyin English
看到他的前女友後,他立刻就走了。 kàndào tā de qián nǚyǒu hòu, tā lìkè jiù zǒu le After seeing his ex-girlfriend, he left immediately.
我吃完飯後,就去睡覺了。 wǒ chī wán fàn hòu, jiù qù shuìjiào le After I finished eating, I went to sleep.

「就」makes the second action feel direct, quick, or natural after the first action.

3. 以前就 / 早就: already before

Use「就」with time words like「以前」or「早」to show that something happened earlier than expected.

Pattern Meaning
Time word + 就 + Verb already did something at that earlier time
Chinese Pinyin English
他們以前就認識。 tāmen yǐqián jiù rènshì They already knew each other before.
我早就知道了。 wǒ zǎo jiù zhīdào le I knew it a long time ago.
她十年前就住在台北了。 tā shí nián qián jiù zhù zài Táiběi le She was already living in Taipei ten years ago.

「早就」is very common. It means “already long ago.”

4. 如果……就……: if..., then...

Use「就」after a condition to show the result. This is one of the most important uses of「就」.

Pattern Meaning
如果 + Condition,Subject + 就 + Result If condition happens, then result happens.
Chinese Pinyin English
如果下雨,我就不出門。 rúguǒ xià yǔ, wǒ jiù bù chūmén If it rains, I will not go out.
如果你累了,就休息一下。 rúguǒ nǐ lèi le, jiù xiūxí yíxià If you are tired, then rest for a bit.

In English, “then” is often optional. In Chinese,「就」is very common in this pattern.

5. 只要……就……: as long as..., then...

「只要……就……」means “as long as..., then...” It shows that one condition is enough for the result to happen.

Pattern Meaning
只要 + Condition,就 + Result as long as the condition is true, the result will happen
Chinese Pinyin English
只要你努力,就會進步。 zhǐyào nǐ nǔlì, jiù huì jìnbù As long as you work hard, you will improve.
只要你想學,我就教你。 zhǐyào nǐ xiǎng xué, wǒ jiù jiāo nǐ As long as you want to learn, I will teach you.

6. 既然……就……: since..., then...

「既然……就……」means “since..., then...” It is used when the condition is already true or accepted as true.

Pattern Meaning
既然 + Fact,就 + Result / Decision since this is true, then...
Chinese Pinyin English
你既然不同意,就算了。 nǐ jìrán bù tóngyì, jiù suàn le Since you disagree, then forget it.
既然你已經知道了,我就不多說了。 jìrán nǐ yǐjīng zhīdào le, wǒ jiù bù duō shuō le Since you already know, I will not say more.

「算了」means “forget it” or “let it go.”

7. 就是 jiù shì: exactly / precisely / this is

「就是」can emphasize that something is exactly the thing you are talking about.

Pattern Meaning
Subject + 就是 + Noun / Description is exactly / is precisely
Chinese Pinyin English
這就是我的家。 zhè jiù shì wǒ de jiā This is my home. / This is exactly my home.
這就是問題。 zhè jiù shì wèntí This is exactly the problem.
他就是我昨天說的人。 tā jiù shì wǒ zuótiān shuō de rén He is exactly the person I talked about yesterday.

「就是」is stronger than「是」because it emphasizes exactness.

8. 我就知道: I knew it

「就」can strengthen a statement and make it sound more certain or expected.

Chinese Pinyin English
我就知道他不會來。 wǒ jiù zhīdào tā bú huì lái I knew he would not come.
我就知道會這樣。 wǒ jiù zhīdào huì zhèyàng I knew it would be like this.

In this use,「就」can suggest “as expected” or “I knew it all along.”

9. 就 / 就只 / 就只有: only / just

「就」can mean “only” or “just,” especially when talking about a small number, limited amount, or limited choice.

Pattern Meaning
就 + Verb / Quantity just / only
就只 / 就只有 only; just only
Chinese Pinyin English
屋裡就剩下我一個人。 wū lǐ jiù shèngxià wǒ yí ge rén I am the only one left in the house.
屋裡就只剩下我一個人。 wū lǐ jiù zhǐ shèngxià wǒ yí ge rén Only I am left in the house.
他就要了一張票,沒多要。 tā jiù yào le yì zhāng piào, méi duō yào He only asked for one ticket and did not ask for more.
他就只要了一張票,沒多要。 tā jiù zhǐ yào le yì zhāng piào, méi duō yào He only asked for one ticket and nothing more.

Adding「只」makes the “only” meaning clearer.

10. 就地 + Verb: do something on the spot

「就地」means “on the spot,” “locally,” or “right where one is.” It is common in fixed expressions.

Chinese Pinyin English
就地取材 jiù dì qǔ cái to use local materials / use what is available nearby
就地休息 jiù dì xiūxí to rest on the spot

This use is more like a fixed word pattern. Beginners can first remember「就地取材」as one phrase.

11. 就 + topic / range + 來 + Verb

「就」can introduce the topic, object, or range of an action. This is more formal, but useful for reading and discussion.

Pattern Meaning
就 + Topic + 來 + Verb regarding this topic, do something
Chinese Pinyin English
我們就這個主題來討論。 wǒmen jiù zhège zhǔtí lái tǎolùn We will discuss this topic. / We will discuss based on this topic.
我們就這個問題來分析。 wǒmen jiù zhège wèntí lái fēnxī We will analyze this issue.

This pattern is common in meetings, classes, reports, and formal discussions.

12. Common mistake: 就 is not always “just”

Many learners translate「就」as “just,” but this does not work in every sentence.

Chinese Better meaning English
我馬上就走。 right away I will leave right away.
他們以前就認識。 already before They already knew each other before.
如果下雨,我就不出門。 then If it rains, then I will not go out.
這就是我的家。 exactly This is exactly my home.

The meaning of「就」depends on the sentence pattern.
