把 sentences (do something to the object)

Doing something TO an object

• Sometimes you want to say what you did to a thing — move it, finish it, break it.
• The (把: marks the object)把bǎ sentence pulls the object in front of the verb to spotlight that.
• I / me我wǒ(把: marks the object)把bǎbook书shū放在fàng zàitable桌子zhuō zi(bound form) up上shàng = "I put the book on the table."

Subj + (把: marks the object)把bǎ + Obj + Verb Phrase

• (把: marks the object)把bǎ moves the object before the verb; the verb says what happened to it.

I我wǒ(把)把bǎbook书shūput放fàngon在zàitable桌子zhuō zion top上shàng。

• I / me我wǒ(把: marks the object)把bǎbook书shū放在fàng zàitable桌子zhuō zi(bound form) up上shàng = "I put the book on the table."

The verb can't be bare

• A (把: marks the object)把bǎ verb needs an extra part ((completed / change)了le, a place, a result): 放在fàng zài…, variant of 吃吃chīto finish完wán(completed / change)了le, to break打破dǎ pò(completed / change)了le.
