Subject + 把 + Object + Verb + Result/了/Complement

The 把 (bǎ) construction — spotlighting what happens to an object

Normal Chinese word order is Subject-Verb-Object, but when you want to spotlight what HAPPENS TO a specific, already-known object — moving it, changing it, finishing it, disposing of it — Chinese often fronts the object with 把 right after the subject, then follows the verb with an extra element (了, a result complement, a directional complement, or a location phrase) showing the object's outcome. Compare plain 我吃了那个苹果 with the 把-sentence 我把那个苹果吃了 — same basic meaning, but 把 puts 'that apple' in the spotlight as a specific thing that got fully dealt with. The deciding question: is the object specific and definite (not 'a/some' thing), and do I want to highlight its fate — and does the verb have something after it describing the result? If either answer is no, skip 把. A bare verb can never end a 把-sentence: 我把苹果吃 is wrong; it needs 了 or a complement.
