如果...就...
Reach for this when you want to say 'if X, then Y.' 如果 sets up a condition; 就 delivers the consequence. It's the most versatile conditional in Chinese — works for real possibilities ('if it rains, I'll stay home'), hypotheticals ('if I were rich...'), and offers ('if you're hungry, just eat'). You'll use it daily.
Structure
如果 [CONDITION], [SUBJECT] 就 [RESULT]
rúguǒ... jiù...
How to Think About It
Unlike English 'if/then', the Chinese pair lives in different positions: 如果 lives at the START of the condition clause; 就 lives right BEFORE the verb of the result clause, not at the start. So the subject of the result clause sits between them: '如果你来, 我就高兴.' Putting 就 at the front of the clause ('如果你来, 就我高兴') is a common learner error.
Examples
如果明天下雨, 我就不去。
Rúguǒ míngtiān xiàyǔ, wǒ jiù bú qù.
If it rains tomorrow, I won't go.
如果你饿了, 就先吃饭吧。
Rúguǒ nǐ è le, jiù xiān chīfàn ba.
If you're hungry, just eat first.
如果有问题, 你就问我。
Rúguǒ yǒu wèntí, nǐ jiù wèn wǒ.
If you have any questions, just ask me.
如果你来，我就很高兴。
Rúguǒ nǐ lái, wǒ jiù hěn gāoxìng.
If you come, I'll be very happy.
如果明天下雨，我们就不去了。
Rúguǒ míngtiān xià yǔ, wǒmen jiù bú qù le.
If it rains tomorrow, we won't go.
如果你想学好中文，就每天听一点。
Rúguǒ nǐ xiǎng xuéhǎo Zhōngwén, jiù měitiān tīng yìdiǎn.
If you want to master Chinese, listen a little every day.
如果下雨, 我们就不去公园。
Rúguǒ xiàyǔ, wǒmen jiù bú qù gōngyuán.
If it rains, we won't go to the park.
如果你不小心碰到了, 就会得病。
Rúguǒ nǐ bù xiǎoxīn pèngdào le, jiù huì débìng.
If you accidentally touch it, you'll get sick.
Common Mistake
English-speaking learners place 就 too early in the result clause, treating it like 'then' which floats at the start. In Chinese 就 anchors to the verb. The subject of the result clause must come BEFORE 就, not after.
如果明天下雨, 就我不去。
如果明天下雨, 我就不去。
Don't Confuse With
只要...就...
只要 means 'AS LONG AS' — a sufficient condition that always triggers the result. 如果 is more neutral ('if X happens'). 只要你来我就高兴 = 'as long as you come I'm happy (no other condition needed)'; 如果你来我就高兴 = 'if you come I'd be happy (maybe you won't).'
要是...就...
Same meaning, more colloquial. 要是 is what you'll hear in casual speech; 如果 works in both speech and writing. Interchangeable in most contexts.
的话
的话 is a softer, optional tag added at the end of the condition clause: '明天下雨的话, 我就不去.' Often combined with 如果 or used alone. Feels gentler, more tentative.
要是... (就)...
Same meaning, more colloquial. Pick 要是 for casual speech and 如果 for writing and news.
的话, ...就...
Use 的话 as a sentence-final 'if' marker; it can replace 如果 or pair with it. 如果...的话...就... is a common reinforced version.
