Three Ways to Move the Object | Chinese (Mandarin) Grammar

In English, the object stays put. "I've read that book," "I finished the homework," "he hasn't even touched the coffee" — the thing acted on sits obediently after the verb, and to move it forward you need special effort ("That book, I've read" with heavy stress, or "As for that book…"). Chinese is far more willing to shift a known object leftward, out of its default post-verb home. But it does not do this by stress alone — it gives you three distinct grammatical tools, and each one moves the object for a different reason. Choosing the right one is a matter of why you are moving it: to talk about it, to say what was done to it, or to flag it as the surprising "even" case. This page is the map; each tool has its own detailed page.

Why move the object at all?

Chinese strongly prefers given-before-new order: information the listener already has drifts to the front, and fresh information stays near the end. A definite, already-known object — 那本书 (nà běn shū) "that book," not just 一本书 "a book" — is old news, so the language likes to move it out of the tail slot where new information belongs. The three tools below are the grammaticalized ways of doing that. This is layered on top of the plain Subject–Verb–Object order; master that first.

Tool	Shape	What it foregrounds	Complement needed?	Register
Topic-fronting	O，S V	aboutness / contrast	no	emphatic
把 construction	S 把 O V+complement	what is DONE to O (disposal)	yes	neutral, frequent
连…都/也	S 连 O 都/也 V	"even" — O as extreme case	no	emphatic

Tool 1 — Topic-fronting: aboutness and contrast

The loosest move: lift the object to the very front as the topic the sentence is about, then comment on it. The object simply sits out front; the rest of the sentence follows in normal order. Reach for this when you want to set something up as "as for X…" or to draw a contrast.

那部电影我早就看过了。

nà bù diànyǐng wǒ zǎojiù kànguo le

That movie, I saw it ages ago. (informal) — the object 那部电影 is fronted as the topic.

咖啡我不喝，茶可以。

kāfēi wǒ bù hē, chá kěyǐ

Coffee I don't drink; tea is fine. (informal) — fronting sets up a clear contrast between two topics.

Topic-fronting is the freest of the three but also the vaguest — a bare fronted noun tells the listener this is what I'm talking about and little more. For the full treatment see topic-fronting and topic–comment structure.

Tool 2 — 把: what is done to the object

The 把 (bǎ) construction moves the object in front of the verb to spotlight what happens to it — how it is disposed of, changed, or affected. Its shape is S + 把 + O + V + complement. The defining constraint: the verb cannot be bare. Something must follow it — a result, a direction, a 了, a completion — because the whole point of 把 is to report an outcome, and a naked verb reports none.

我把作业写完了。

wǒ bǎ zuòyè xiěwán le

I finished the homework. (neutral) — 完 is the complement showing the result.

请把门关上。

qǐng bǎ mén guānshàng

Please close the door. (neutral) — 上 completes the verb; 把 is the everyday, unmarked choice here.

Unlike the other two tools, 把 is register-neutral and extremely common — it is not an emphatic flourish but the default way to say "do something to a definite object." It is also the most rule-bound: see 把 overview, why the verb can't be bare, and when 把 is required.

Tool 3 — 连…都/也: the "even" object

The 连…都/也 frame moves the object forward and wraps it in "even," marking it as the extreme, surprising case. Its shape is S + 连 + O + 都/也 + V. Use it when the point is not just which object but that even this one is included.

他连我的名字都记不住。

tā lián wǒ de míngzi dōu jì bu zhù

He can't even remember my name. (informal) — 名字 is fronted and flagged as the 'even' case.

这本书连老师都没读过。

zhè běn shū lián lǎoshī dōu méi dúguo

Even the teacher hasn't read this book. (neutral)

The shared rule: the object must be definite

Whichever tool you pick, the object you move has to be definite / specific — 那本书 "that book," 你的名字 "your name," 这杯咖啡 "this coffee." You cannot front, 把, or 连…都 an indefinite "a book." This follows straight from the given-before-new logic: only known information moves left; brand-new indefinite things belong after the verb.

那本书我看过。

nà běn shū wǒ kànguo

That book, I've read. (neutral) — a definite object like 那本书 fronts freely; an indefinite 一本书 'a book' cannot move left like this.

Watch the same definite object take all three forms:

Tool	Sentence	Nuance
topic	那杯咖啡我喝了。	That coffee — I drank it. (about it)
把	我把那杯咖啡喝完了。	I finished off that coffee. (what I did to it)
连…都	他连那杯咖啡都没喝。	He didn't even drink that coffee. (even this)

那杯咖啡我喝了，你的还在桌子上。

nà bēi kāfēi wǒ hē le, nǐ de hái zài zhuōzi shàng

That coffee, I drank it; yours is still on the table. (informal) — topic-fronting.

我把那杯咖啡喝完了，再给我来一杯。

wǒ bǎ nà bēi kāfēi hēwán le, zài gěi wǒ lái yì bēi

I finished that coffee — get me another. (informal) — 把 + result complement 完.

💡

Not every verb can move its object. Static and perception verbs — 有 (have), 是 (be), 知道 (know), 喜欢 (like) — resist 把 because nothing is "done to" their object. With those, topic-fronting or 连…都 still works (我喜欢的书，你别动 / 他连你都不认识), but 把 does not. When you want 把 and it feels wrong, check whether the verb actually affects its object.

Choosing between them

Want to say "as for X…" or draw a contrast, with no particular outcome in view? → topic-fronting.
Want to report what was done to X — a result, a change, a completion? → 把 (and give the verb a complement).
Want to flag X as the surprising "even" case? → 连…都/也.

Register is part of the choice too: 把 is the neutral workhorse you will use constantly, while topic-fronting and 连…都 add emphasis or contrast on top of the bare fact.

Common Mistakes

1. A bare verb after 把. The single most common 把 error. 把 demands a complement — a result, direction, 了, or completion — never a naked verb.

❌ 我把门关。

Incomplete — 把 forbids a bare verb; add a complement: 我把门关上.

✅ 我把门关上。

wǒ bǎ mén guānshàng

I closed the door. — 上 completes the verb.

2. Fronting an indefinite object. Only a definite, known object can move left; "a book" cannot be topicalized or put in a 把 sentence.

❌ 我把一本书看完了。

Wrong — 把 needs a definite object; use 那本书 or drop 把: 我把那本书看完了 / 我看完了一本书.

✅ 我把那本书看完了。

wǒ bǎ nà běn shū kànwán le

I finished that book. — the object is definite.

3. Using 把 with a verb that doesn't affect its object. State and perception verbs (知道, 喜欢, 有) can't take 把 — nothing is disposed of. Front the object as a topic instead.

❌ 我把这件事知道了。

Wrong — 知道 doesn't 'act on' its object; use topic order: 这件事我知道了.

✅ 这件事我知道了。

zhè jiàn shì wǒ zhīdào le

This matter, I already know. — topic-fronting, not 把.

4. Dropping the 都/也 in a 连 sentence. When you choose the "even" route, the 都/也 anchor is obligatory (a whole trap in its own right).

❌ 他连那本书看过。

Incomplete — 连 needs 都/也: 他连那本书都看过.

✅ 他连那本书都看过。

tā lián nà běn shū dōu kànguo

He's even read that book. — 都 anchors the 'even'.

Key Takeaways

Chinese moves a definite object leftward with three tools, each for a different reason.
Topic-fronting (那本书我看过): aboutness or contrast; loosest, no complement, emphatic.
把 (我把那本书看完了): what is done to the object; the verb must take a complement; neutral and very frequent.
连…都/也 (他连那本书都看过): the object as the surprising "even" case; the 都/也 is obligatory.
All three require a definite object — this follows from Chinese's given-before-new preference; indefinite "a book" stays after the verb.
Verbs that don't affect their object (知道, 喜欢, 有) block 把, but still allow topic-fronting or 连…都.
