Using "ba" sentences

Also known as: 把字句 (Bǎzì Jù), 把 construction, disposal construction, preposition 把 and pre-transitive 把.

The 把 sentence is a useful structure for focusing on the result or influence of an action. It's really common in Mandarin, but can feel a bit strange for English speakers at first.

How to form a 把 sentence

Basic 把 sentences

A basic sentence in Mandarin is formed with a subject-verb-object (SVO) word order, as in English:

我吃了馒头。

A 把 sentence shakes things up a bit, and you get this structure:

Subject + 把 + Object + Verb

So you now have a SOV word order

我把馒头吃下了。

You might notice that another character crept in after the verb. This is because 把 sentences are used for describing what happened to the object. This is often described as the disposal of the object. As well as the verb, you need to indicate that the action was completed and applied to the object. In this case 下 indicates this 'disposal'.

The idea of disposal will be covered in more detailed below. For now just remember that a 把 sentence must describe what happened to the object in the end. A useful way of thinking about it is that 把 is similar to saying "What I did with ... was ... " or "What happened to ... was ..."

Basic 把 sentences

Subject	把	Object	Verb	Disposal
我	把	那 本 书	放	在 桌子 上	。
你	把	你的作业	做	好	。
他	把	我的 钱包	偷	走 了	。
她	把	我的车	修	好了	。
您	把	您的 姓名	写	下来	。

Negating 把 sentences

To negate a 把 sentence, insert 不 (present) or 没有 (past) directly in front of 把. You can't put it after 把, 'inside' the 把 construction, as this would break the rule about describing what happened to the object. It would be like saying "What happened to ... was nothing". It doesn't sound natural.

Negating 把 sentences

我	没有	把	你的 电脑	弄坏	了	。
你	不要	把	我的 啤酒	喝	完	。
他	不	把	钥匙	拿	起来	。
