  • Purpose clauses.
  • Compact action sequences.

Hypothesis and result

Pitfall: A hypothetical condition need not already be true.

…的话,就…

A clause as condition

的话 after a clause frames it as a condition, with 就 commonly introducing the result.

你不去的话,我就自己去。

Nǐ bù qù de huà, wǒ jiù zì jǐ qù.

If you don't go, I'll go by myself.

More

Pitfall: The conditional marker follows the condition rather than preceding it.

只有…,才…

Necessary conditions

只有…才… presents a requirement for a result. Meeting the requirement need not alone guarantee success.

Zhǐ yǒu mǎi piào, cái néng jìn qù.

More

Pitfall: Do not swap this with 只要 without changing the claimed relationship.

只要…,就…

Sufficient conditions

只要…就… presents a condition as enough for the stated result.

只要你愿意,我们就一起去。

Zhǐ yào nǐ yuàn yì, wǒ men jiù yī qǐ qù.

More

Pitfall: This does not say willingness is the only possible condition in all contexts.

为了…,…

Purpose clauses

为了 introduces the intended goal of an action. The goal can come before the main clause.

Wèi le gǎn chē, tā hěn zǎo jiù chū mén le.

He left early to catch the vehicle.

More

Pitfall: The goal is not automatically guaranteed to be achieved.

吃了饭

Compact action sequences

A bounded first action with 了 can lead directly to a following action, often with 就.

吃了饭就走。

Chī le fàn jiù zǒu.

Leave after eating.

More

Pitfall: Here the first action can still be future relative to now; 了 is not simply past tense.
