Making Logical Inferences: 'Since... Then...' (既然...就...)

Use {既然|jìrán} for known facts and {就|jiù} for the resulting decision or suggestion.

Grammar Rule in 30 Seconds

Use {既然|jìrán} to state a known fact and {就|jiù} to draw a logical conclusion from it.

  • Place {既然|jìrán} at the start of the clause stating the established fact.
  • Place {就|jiù} in the second clause to introduce the resulting action or deduction.
  • The subject can go before or after {既然|jìrán} depending on emphasis.
既然 (Fact) + 就 (Conclusion)

Overview

At the heart of logical reasoning in Mandarin Chinese is the structure 既然...就... (jìrán...jiù...). This pattern is your tool for moving from an established, mutually-acknowledged fact to a logical conclusion or suggestion. Think of it as the linguistic equivalent of saying, "Given that X is an undeniable reality, Y is the most rational course of action." It's not used to introduce new information or explain the hidden cause of something; rather, it takes a premise that is already on the table—a situation everyone is aware of—and uses it as a springboard for what should happen next.

Its function is fundamentally pragmatic. Imagine you and a friend arrive at a concert only to find the main act has cancelled. The fact is established.

Now what? You might say: 既然主唱不来了,我们就回家吧 (jìrán zhǔchàng bù lái le, wǒmen jiù huíjiā ba) — "Since the lead singer isn't coming, let's just go home." The 既然 clause doesn't explain why the singer isn't coming; it simply takes the reality of the situation to propose a logical next step. This makes it an essential structure for decision-making, persuasion, and practical problem-solving in daily conversation and formal contexts alike.

Mastering 既然...就... allows you to sound not just fluent, but also rational and decisive. It signals to your listener that you are considering the circumstances and responding to them thoughtfully. The tone can range from a straightforward suggestion to a feeling of reluctant acceptance or even a forceful argument, depending entirely on the context and the conclusion you draw.

How This Grammar Works

The 既然...就... pattern operates on a principle of logical inference, connecting a premise to a conclusion. To understand its mechanics, we must distinguish it from simple cause-and-effect structures like 因为...所以... (yīnwèi...suǒyǐ...). While 因为 explains the objective reason for a result, 既然 presents a subjective or intersubjective justification for a proposed action or judgment.
The premise introduced by 既然 is not a hidden cause to be revealed, but a shared piece of knowledge.
Let's break down the two components:
  1. 1The Premise: 既然 (jìrán) + Accepted Fact
The first clause sets the stage. The word 既然 literally translates to "since" or "now that." It must be followed by a statement that is considered true and known by all parties in the conversation. This could be a freshly discovered fact (既然下雨了 - Since it's raining now), a long-standing condition (既然你是他最好的朋友 - Since you are his best friend), or something someone has just said.
The key is that this premise is the undisputed starting point for the reasoning that follows.
  1. 1The Inference: 就 (jiù) + Conclusion/Suggestion
The second clause delivers the logical payload. The adverb (jiù) is the critical link, translating here as "then" or "in that case." It signals that what follows is a direct and rational consequence of the premise. This consequence is not a foregone conclusion in the objective sense; it is the speaker's proposed course of action, opinion, or judgment.
For instance, in 既然你已经毕业了,就应该开始找工作了 (jìrán nǐ yǐjīng bìyè le, jiù yīnggāi kāishǐ zhǎo gōngzuò le), graduating doesn't automatically cause one to look for a job, but it provides the logical grounds for the suggestion that one should.
This structure reflects a specific mode of thinking: you are not explaining the world as it is, but rather navigating it. You accept Reality A (既然...) and therefore propose Action B (...就...). This is why it is so frequently used for giving advice, making plans, or arguing a point—it is the grammar of rational response.

Formation Pattern

1
To use 既然...就... correctly, you need to pay close attention to subject placement and the choice of the second connector. While is the most common partner for 既然, other adverbs like (yě), (hái), or (nà) can be used to add nuance.
2
Core Formulas
3
Single Subject (Subject before 既然): This is common when the same person/thing is the subject of both clauses.
4
Formula: Subject + 既然 + Premise, 就 + Conclusion
5
Example: 你既然不想去,就别勉强自己了。 (Nǐ jìrán bù xiǎng qù, jiù bié miǎnqiǎng zìjǐ le.) — Since you don't want to go, then don't force yourself.
6
Single Subject (Subject after 既然): Also very common and often interchangeable with the first pattern.
7
Formula: 既然 + Subject + Premise, 就 + Conclusion
8
Example: 既然你不想去,就别勉强自己了。 (Jìrán nǐ bù xiǎng qù, jiù bié miǎnqiǎng zìjǐ le.) — Since you don't want to go, then don't force yourself.
9
Different Subjects: When the subjects of the two clauses are different, they must be stated clearly.
10
Formula: 既然 + Premise (with Subject 1), Subject 2 + 就 + Conclusion
11
Example: 既然天气这么好,我们就在外面吃饭吧。 (Jìrán tiānqì zhème hǎo, wǒmen jiù zài wàimiàn chīfàn ba.) — Since the weather is so good, let's eat outside.
12
Variations in the Second Clause
13
The connector in the second clause is crucial. While is the default, other adverbs can subtly change the meaning.
14
| Connector | Pinyin | Function & Nuance | Example |
15
| :--- | :--- | :--- | :--- |
16
| | jiù | The standard, default choice. Indicates a direct, logical, and expected consequence. | 既然时间不早了,我们走吧。 (Jìrán shíjiān bù zǎo le, wǒmen jiù zǒu ba.) — Since it's getting late, let's go. |
17
| 那/那么 | nà/nàme | Adds a sense of "well, in that case..." It softens the transition and is extremely common in conversation. 那就 is a frequent combination. | 既然大家都同意,我们就这么定了。 (Jìrán dàjiā dōu tóngyì, wǒmen jiù zhème dìng le.) — Since everyone agrees, well then, let's decide on this. |
18
| | | Implies a sense of "might as well" or "still." It's used when the action is perhaps not ideal but logical given the circumstances, or to show resignation. | 既然钱已经花了,退不了,那我们只能接受了。 (Jìrán qián yǐjīng huā le, tuì bù liǎo, nà wǒmen zhǐ néng jiēshòu le.) — Since the money is already spent and can't be refunded, we can only accept it. |
19
| | hái | Used in questions to mean "still" or to express a degree of challenge or disbelief. It often translates as "why bother" or "what's the point of..." | 你既然都知道了,问我做什么? (Nǐ jìrán dōu zhīdào le, hái wèn wǒ zuò shénme?) — Since you already know everything, what are you still asking me for? |
20
Finally, the second clause often ends with a modal particle like (ba) to frame the conclusion as a suggestion, or (le) to state it as a decision or a new reality.

When To Use It

This pattern is versatile and appears across various contexts, from casual chats to formal arguments. Understanding its primary functions will help you use it effectively.
1. To Make Suggestions and Give Advice
This is the most common usage. You observe a situation and propose a logical course of action. It's a gentle yet firm way to guide someone's decision.
  • 既然你这么累,就应该请一天假好好休息。 (Jìrán nǐ zhème lèi, jiù yīnggāi qǐng yī tiān jià hǎohǎo xiūxī.) — Since you're so tired, you should take a day off to rest properly.
  • 既然菜快凉了,那我们就别等他了,先吃吧。 (Jìrán cài kuài liáng le, nà wǒmen jiù bié děng tā le, xiān chī ba.) — Since the food is getting cold, then let's not wait for him and start eating.
2. To Express Resignation or Acceptance (Making the Best of It)
Sometimes you're faced with an unchangeable situation. 既然 acknowledges this reality, and the clause expresses how you've decided to proceed. It often carries a tone of "well, so be it."
  • 既然分手是无法避免的,那就坦然面对吧。 (Jìrán fēnshǒu shì wúfǎ bìmiǎn de, nà jiù tǎnrán miànduì ba.) — Since breaking up is unavoidable, then let's just face it calmly.
  • 既然已经错过了末班车,我们也就只能打车回家了。 (Jìrán yǐjīng cuòguò le mòbānchē, wǒmen yě jiù zhǐnéng dǎchē huíjiā le.) — Since we've already missed the last bus, we have no choice but to take a taxi home.
3. To Build an Argument or Persuade
A powerful rhetorical use of this pattern is to take a fact your counterpart has presented or agreed to and use it as the foundation for your own argument. This makes your point seem like the only logical conclusion.
  • 你既然同意成本是个问题,就不应该再提这个昂贵的方案。 (Nǐ jìrán tóngyì chéngběn shì ge wèntí, jiù bù yīnggāi zài tí zhège ángguì de fāng'àn.) — Since you agree that cost is an issue, you shouldn't bring up this expensive proposal again.
  • 既然你说客户永远是对的,那这次我们就应该听客户的。 (Jìrán nǐ shuō kèhù yǒngyuǎn shì duì de, nà zhè cì wǒmen jiù yīnggāi tīng kèhù de.) — Since you say the customer is always right, then we should listen to the customer this time.
4. To Ask Rhetorical Questions
By pairing 既然 with a question word like 为什么 (wèishéme) or 何必 (hébì), you can challenge the logic of someone's actions. You are pointing out a contradiction between a known fact and their behavior.
  • 你既然不喜欢他,为什么还要答应跟他约会呢? (Nǐ jìrán bù xǐhuān tā, wèishéme hái yào dāyìng gēn tā yuēhuì ne?) — Since you don't like him, why did you agree to go on a date with him?
  • 既然事情已经解决了,你何必还在这里生闷气? (Jìrán shìqíng yǐjīng jiějué le, nǐ hébì hái zài zhèlǐ shēng mènqì?) — Since the matter is already resolved, why are you still here sulking?

Common Mistakes

Learners often stumble when navigating the nuances of 既然...就.... Avoiding these common pitfalls is key to using the structure naturally.
| Mistake | Incorrect Example | Correct Example & Explanation |
| :--- | :--- | :--- |
| Confusing with 因为 | *既然我生病了,所以我没来。 (Jìrán wǒ shēngbìng le, suǒyǐ wǒ méi lái.) | Correct: 因为我生病了,所以我没来。 (Yīnwèi wǒ shēngbìng le, suǒyǐ wǒ méi lái.) Explanation: 因为 explains the reason for a past event (why I didn't come). 既然 is used to propose a future action based on a present fact. A correct 既然 sentence would be: 既然我生病了,今天的会议就取消吧。 (Since I am sick, let's cancel today's meeting.) |
| Dropping or the second connector | *既然你来了,我们开始吧。 (Jìrán nǐ lái le, wǒmen kāishǐ ba.) | Correct: 既然你来了,我们开始吧。 (Jìrán nǐ lái le, wǒmen jiù kāishǐ ba.) Explanation: English allows for dropping "then" ("Since you're here, let's start."), but in Chinese, the second connector (, , ) is almost always required to bridge the premise and the conclusion. Omitting it makes the sentence sound incomplete. |
| Using for a Hypothetical Premise | *既然明天下雪,我们就不滑了。 (Jìrán míngtiān xiàxuě, wǒmen jiù bù huá le.) | Correct: 如果明天下雪,我们就不滑了。 (Rúguǒ míngtiān xiàxuě, wǒmen jiù bù huá le.) Explanation: 既然 requires the premise to be a known fact. You cannot know for certain it will snow tomorrow. For hypothetical or conditional situations, you must use 如果 (rúguǒ), 要是 (yàoshi), or a similar word for "if." |
| Using 所以 instead of | *既然你不舒服,所以你应该回家。 (Jìrán nǐ bù shūfu, suǒyǐ nǐ yīnggāi huíjiā.) | Correct: 既然你不舒服,应该回家。 (Jìrán nǐ bù shūfu, jiù yīnggāi huíjiā.) Explanation: The pair 因为...所以... is a fixed structure for cause and effect. 既然 has its own partners (, , ). Mixing them by using 既然...所以... is grammatically incorrect in standard Mandarin, as 既然 already establishes the logical link. |
| Incorrect Subject Placement in Second Clause | *既然电影开始了,就我们进去吧。 (Jìrán diànyǐng kāishǐ le, jiù wǒmen jìnqù ba.) | Correct: 既然电影开始了,我们进去吧。 (Jìrán diànyǐng kāishǐ le, wǒmen jiù jìnqù ba.) Explanation: The adverb (, , etc.) must come after the subject of the second clause. The correct order is always Subject + Adverb + Verb. |

Real Conversations

Textbook examples are useful, but seeing 既然...就... in modern, authentic contexts reveals its true flexibility. Here are a few scenarios showing how it's used in daily life.

S

Scenario 1

Office Communication (on a messaging app like WeChat Work)

> 小张 (Xiǎo Zhāng): 抱歉,我今天家里有急事,下午的会可能要晚到一会儿。

> (Bàoqiàn, wǒ jīntiān jiālǐ yǒu jíshì, xiàwǔ de huì kěnéng yào wǎn dào yīhuìr.)

> Sorry, I have a family emergency today, I might be a little late for the afternoon meeting.

>

> 李经理 (Manager Lǐ): 没事,家庭为重。既然这样,我们就把会议推迟半小时,等你到了再开始。

> (Méishì, jiātíng wéizhòng. Jìrán zhèyàng, wǒmen jiù bǎ huìyì tuīchí bàn xiǎoshí, děng nǐ dào le zài kāishǐ.)

> No problem, family is more important. Since that's the case, let's postpone the meeting by half an hour and start when you arrive.

S

Scenario 2

Making Plans with Friends (Texting)

> A: 这家餐厅排队的人也太多了吧!估计要等一个小时。

> (Zhè jiā cāntīng páiduì de rén yě tài duō le ba! Gūjì yào děng yī ge xiǎoshí.)

> The line for this restaurant is way too long! I estimate we'll have to wait an hour.

>

> B: 太夸张了。既然要等这么久,那咱们换一家吧?附近有家日料还不错。

> (Tài kuāzhāng le. Jìrán yào děng zhème jiǔ, nà zánmen huàn yī jiā ba? Fùjìn yǒu jiā rìliào hái bùcuò.)

> That's crazy. Since we have to wait that long, then how about we switch to another place? There's a decent Japanese restaurant nearby.

S

Scenario 3

A Heart-to-Heart Conversation

> 朋友A (Friend A): 我真的很讨厌现在的工作,但是又不敢辞职。

> (Wǒ zhēn de hěn tǎoyàn xiànzài de gōngzuò, dànshì yòu bù gǎn cízhí.)

> I really hate my current job, but I don't dare to quit.

>

> 朋友B (Friend B): 你既然每天都这么痛苦,就应该勇敢地做出改变。我们可以先一起看看新的工作机会,不一定要马上辞职。

> (Nǐ jìrán měitiān dōu zhème tòngkǔ, jiù yīnggāi yǒnggǎn de zuòchū gǎibiàn. Wǒmen kěyǐ xiān yīqǐ kànkan xīn de gōngzuò jīhuì, bù yīdìng yào mǎshàng cízhí.)

> Since you're so miserable every day, you should be brave and make a change. We can start by looking at new job opportunities together; you don't have to resign immediately.

Quick FAQ

Q: Can I use 既然 on its own without a second clause?

No. 既然 functions as a subordinating conjunction that creates an expectation. A sentence like 既然你来了... (Since you've come...) hangs in the air, incomplete. It requires a main clause with a connector like or to resolve the logic it introduces.

Q: Is 既然...就... always used for making suggestions with ?

Not at all. While suggestions are a very common use case, the pattern is broader. It can be used to state a firm decision (...我们就这么办), declare an unavoidable outcome (...我也只能接受), or pose a sharp rhetorical question (...为什么还...?). The conclusion determines the force of the statement, not the structure itself.

Q: How formal is this pattern? Is it okay for texting?

It's a highly versatile pattern that works across the full spectrum of formality. It is extremely common in casual conversation and texting (既然都到饭点了就出来吃饭呗 - Since it's dinnertime, just come out and eat). At the same time, its logical nature makes it perfectly suitable for formal essays, business proposals, and speeches (既然市场趋势已经明确,我司就必须调整战略布局 - Since the market trend is already clear, our company must adjust its strategic layout).

Q: Is the only word I can use in the second clause?

No. As detailed in the Formation section, is the most common and neutral choice. However, 那/那么 (nà/nàme) is frequently used to add a conversational "well then..." feel. (yě) introduces a sense of resignation ("might as well"), and (hái) is typically used in rhetorical questions to mean "still."

Q: Does the premise in the 既然 clause have to be something negative?

Absolutely not. The premise is simply a fact, which can be positive, negative, or neutral. For example, a host at a party might say: 既然大家都到齐了,那我们就开动吧! (Jìrán dàjiā dōu dàoqí le, nà wǒmen jiù kāidòng ba!) — "Since everyone has arrived, then let's start eating!" Here, the premise is a positive and happy fact.
