Dropping Objects and Pro-Drop | Chinese (Mandarin) Grammar

English forces you to fill every slot. "Did you buy it?" — "Yes, I bought it." You cannot say "Yes, I bought"; the object it is grammatically obligatory even when everyone in the room knows what "it" is. Chinese does the opposite: anything the listener can recover from context simply disappears. The answer to "Did you buy it?" is often just 买了 — "bought" — with no pronoun for either the buyer or the thing bought. Linguists call this pro-drop (dropping pronouns) and, more broadly, argument ellipsis. For an English speaker the hard part isn't learning to drop — it's learning to stop inserting the reflexive "it," because a literal 它 where Chinese wants nothing is one of the clearest tells of a translated-from-English sentence.

Answering by echoing the verb

The most common place you'll meet this is in short answers. Chinese doesn't have all-purpose "yes/no" words the way English does; instead, you echo the verb of the question, and everything recoverable — subject, object — drops away. "Did you see it?" → "Saw." "Are you going?" → "Going." (This verb-echo answering has its own page: answering with the verb.)

你看了吗？——看了。

nǐ kàn le ma? — kàn le

Did you see it? — Yes (I did). (informal) — no 'it', no 'I'; just the echoed verb.

苹果买了没有？——买了，放冰箱里了。

píngguǒ mǎi le méiyǒu? — mǎi le, fàng bīngxiāng li le

Did you get the apples? — Yes, I put them in the fridge. (informal) — the apples are the topic; both replies drop the object entirely.

你喜欢这部电影吗？——很喜欢。

nǐ xǐhuan zhè bù diànyǐng ma? — hěn xǐhuan

Do you like this movie? — I really do. (informal) — English needs 'like it'; Chinese drops the object.

There is no obligatory "it"

This is the rule to tattoo on your hand. English it is doing grammatical work — filling the object slot — as much as it's pointing at anything. Chinese has no such requirement. "I know (it)" is 我知道; "I bought (it)" is 我买了; "I've read (it)" is 我看过. The object slot is simply left empty when the thing is obvious.

这件事我知道，你不用再说了。

zhè jiàn shì wǒ zhīdào, nǐ búyòng zài shuō le

I know about that — you don't need to say any more. (informal) — 知道 with no object; the matter is fronted as topic.

我的钥匙呢？——我拿着呢，给你。

wǒ de yàoshi ne? — wǒ ná zhe ne, gěi nǐ

Where are my keys? — I've got them, here. (informal) — 拿着 and 给 both drop the object 'them'.

The pronoun 它 (tā, "it") does exist, but it's used sparingly — mostly for animals you're treating as individuals, or occasionally to keep a clause from collapsing when the object really needs to be visible for emphasis or as a topic. For a plain inanimate object recoverable from context, native speakers leave it out.

这只小狗太可爱了，我们养它吧！

zhè zhī xiǎo gǒu tài kě'ài le, wǒmen yǎng tā ba!

This puppy is so cute — let's keep it! (informal) — 它 is natural here for an animal treated as an individual.

💡

The test: if you're about to write 它 for an inanimate "it," delete it and see if the sentence still makes sense. Nine times out of ten it does — and it sounds more native. Keep 它 for animals and for the rare case where the object must stay visible.

Subjects drop too

Pro-drop isn't only about objects. Once a subject is established, it vanishes from the following clauses. A string of actions by the same person is a topic chain: name the subject once, then let a run of verbs share it. Repeating 我 in front of every verb sounds childish and heavy — Chinese threads them together instead.

去不去？——去。

qù bu qù? — qù

Are you going? — Yes. (informal) — both the subject 'you/I' and everything else drop; the bare verb is the whole answer.

我早上起床、刷牙、吃饭，然后去上班。

wǒ zǎoshang qǐchuáng, shuā yá, chī fàn, ránhòu qù shàng bān

In the morning I get up, brush my teeth, have breakfast, then go to work. (neutral) — 我 appears once; the following verbs share it.

When you can't drop

Dropping is licensed by recoverability, so the limit is simple: keep the argument when it's new information or when leaving it out would be ambiguous or contrastive. If the listener can't reconstruct who or what you mean, you must name it. Introducing something for the first time, or contrasting two things, is exactly when the object stays.

我买了一本书和一支笔，书给你，笔我自己用。

wǒ mǎi le yì běn shū hé yì zhī bǐ, shū gěi nǐ, bǐ wǒ zìjǐ yòng

I bought a book and a pen — the book's for you, the pen I'll use myself. (informal) — the objects are kept because they're being contrasted.

Common Mistakes

1. Inserting 它 for "it" as an object. For a recoverable inanimate thing, drop it.

❌ 我买了它。

Unnatural — a bare object-'it' isn't used this way. For 'I bought it', say 我买了.

✅ 我买了。

wǒ mǎi le

I bought it. — the object drops; 了 alone completes the reply.

2. Adding 它 to a "do you like it?" answer. The object of 喜欢 drops when obvious.

❌ 你喜欢它吗？

Unnatural for an inanimate thing — say 你喜欢吗? and let context supply what's liked.

✅ 你喜欢吗？

nǐ xǐhuan ma?

Do you like it? — no object pronoun needed.

3. Tacking 它 onto 看见 / 看到. "I saw it" is just the verb.

❌ 我看见它了。

Unnatural — for 'I saw it' about an object, say 我看见了.

✅ 我看见了。

wǒ kàn jiàn le

I saw it. — object dropped, 了 marks completion.

4. Repeating the subject in every clause. Once established, let it drop across the chain.

❌ 我起床，我吃饭，我去上班。

Heavy and unnatural — don't repeat 我. Say 我起床、吃饭，然后去上班.

✅ 我起床、吃饭，然后去上班。

wǒ qǐchuáng, chī fàn, ránhòu qù shàng bān

I get up, eat, then go to work. — one subject shared across the chain.

Key Takeaways

Chinese drops any argument the context can recover — objects and subjects alike; English's obligatory "it" has no equivalent.
Short answers usually echo the verb (看了, 去), with subject and object dropped — see answering with the verb.
它 ("it") is used sparingly — mainly for animals or when the object must stay visible; delete a reflexive 它 and the sentence usually improves.
Once a subject is set, it vanishes across a topic chain; repeating 我 in every clause sounds childish.
Keep an argument only when it's new, ambiguous, or contrastive — recoverability is the whole rule.
