把 (ba) sentences

Core idea

把 brings a known object forward so the sentence can focus on what happens to it. The object is usually moved, changed, placed, handed over, opened, closed, eaten, finished, or otherwise affected.

A bare verb is usually not enough. The sentence normally needs a result, direction, placement, recipient, completion marker, or some other element that shows the outcome of the action.

When it works

Do not use 把 just because a sentence has an object. Use it when the object is identifiable and the sentence is about how the action handles that object.

The object after 把 is usually definite: something already known, visible, possessed, or otherwise specific. Indefinite objects are usually introduced with a normal verb-object sentence first.

Negation and commands come before 把. That means the sentence controls the whole handling event, not only the verb after the object.

When not to force it

If the sentence merely says that someone did an action to some object, a normal verb-object sentence may be better. 把 earns its place when the object is known and the sentence shows a clear affected outcome.

Examples

请把门关上。

Qǐng bǎ mén guān shàng.

Please close the door.

The door is a known object affected by the action.

他把书放在桌上。

Tā bǎ shū fàng zài zhuō shàng.

He put the book on the table.

我把票给朋友了。

Wǒ bǎ piào gěi péngyǒu le.

I gave the ticket to my friend.
