把…了 grammar point · tier 1 · disposal-completed 把 O V 了 (deal with the object, and it's done/gone)
Fronts a definite object with 把, then disposes of it with a verb closed by 了: the thing gets dealt with and is gone or used up.

Hook inherited from .

Fronts a definite object with 把, then disposes of it with a verb closed by 了
框 · Frame
[subj] 把 [definite obj] [verb] 了
觸 · Trigger
You want to say a specific thing got dealt with for good — sold, thrown out, eaten up, finished off.
序 · The move
1Take the definite thing you act on and place it after 把.Is the object specific (this/that/it), not any-old-one? 把 refuses an indefinite object.
2Put the disposing verb after the object.Does the verb change or remove the object (sell, throw, eat, finish)? A bare static verb won't dispose.
3Close with 了 to mark the disposal done.Is the thing now gone or transformed? If nothing happened to it, the pattern doesn't apply.
例 · Examples
1這件衣服穿不下,我打算fronts the object for disposalit — the definite object (the top)sell — the disposing verbmarks the selling as done/settled
This top doesn't fit anymore, so I'm planning to sell it off.
界 · Boundary
把 (disposal, no 了)
Plain 把…V acts on the object; 把…V了 adds that the act is finished and the thing is gone. The 了 is the full stop on the disposal.
把 O V 了 keeps the subject as the doer disposing of the thing; 被 flips the spotlight so the thing is the one acted upon. Same event, opposite agent in front.
了1 (plain completion)
V了 alone just completes the verb; 把 O V 了 first fronts a definite object and demands the verb dispose of it. Without 把 there is no fronted-object disposal frame.
✗ 我把一本書賣了。 → ✓ 我把那本書賣了。 (把 needs a definite object, not 'a book')
✗ 我把它喜歡了。 → ✓ 我把它丟了。 (the verb must dispose of the object; 喜歡 acts on nothing)
✗ 我把它賣。 → ✓ 我把它賣了。 (the disposal needs 了 to read as done)
English keeps the object after the verb ('I sold it'), so learners drop 把 and front nothing. Chinese pulls the definite object ahead of the verb and seals the result with 了.
