If appearance sentences say something stepped onto the scene, disappearance sentences are their exact mirror: something dropped off it. And Chinese treats the two as one family. Just as 来了一个人 "someone came" puts the newcomer after the verb, 死了一条鱼 "a fish died" and 丢了一个钱包 "a wallet got lost" put the vanished thing after the verb too. The logic is identical — an event has changed the inventory of the scene, and the affected participant is presented as an indefinite quantity, so it lands in the focus slot at the end. If you've learned presentative appearance, you already know the shape; this page just runs it in reverse.
The pattern: (Place/Owner) + V + 了 + indefinite noun
A setting (a place or a possessor) leads, a change-of-state verb marked with 了 follows, and the thing that was lost — indefinite, number + measure word — comes last.
| (Setting) | Verb + 了 | Indefinite noun | Meaning |
|---|---|---|---|
| — | 丢了 (diū le) | 一个钱包 (yí gè qiánbāo) | a wallet got lost |
| 鱼缸里 (yúgāng lǐ) | 死了 (sǐ le) | 一条金鱼 (yì tiáo jīnyú) | a goldfish died |
| 家里 (jiā lǐ) | 少了 (shǎo le) | 一个人 (yí gè rén) | the family is one person short |
昨天家里丢了一辆自行车。
zuótiān jiā lǐ diū le yí liàng zìxíngchē
A bicycle went missing from home yesterday. (informal) — the lost thing, indefinite, follows the verb.
鱼缸里死了一条金鱼。
yúgāng lǐ sǐ le yì tiáo jīnyú
A goldfish died in the tank. (neutral) — 死了 + indefinite noun.
我们班这学期又走了一个同学。
wǒmen bān zhè xuéqī yòu zǒu le yí gè tóngxué
Another classmate has left our class this term. (informal) — 走了一个 = 'one left'.
Why the affected thing is indefinite and comes last
These verbs — 死 (die), 丢 (get lost), 少 (be short/missing), 跑 (run off), 走 (leave), 塌 (collapse), 断 (break) — are intransitive change-of-state verbs. The noun after them is not an object being acted on by some agent; it's the entity that undergoes the change. In 死了一条鱼, nobody killed the fish — the fish is simply the one that died. Grammatically this participant behaves like the thing presented, so, exactly as with appearance, it's introduced as an indefinite quantity in the end-focus slot. The 了 here is the perfective 了 (with a strong change-of-state flavor): the event is complete, the scene is now different.
冰箱里少了半瓶牛奶，谁喝的？
bīngxiāng lǐ shǎo le bàn píng niúnǎi, shéi hē de?
Half a bottle of milk is missing from the fridge — who drank it? (informal) — 少了 presents the shortfall.
路上死了一只猫，看着真让人难受。
lù shàng sǐ le yì zhī māo, kànzhe zhēn ràng rén nánshòu
A cat died in the road — it's really upsetting to see. (informal) — 死了 + indefinite animal.
名单上好像少了一个名字。
míngdān shàng hǎoxiàng shǎo le yí gè míngzi
A name seems to be missing from the list. (neutral) — 少了 works for abstract 'gaps' too.
The neat symmetry: 多 vs 少
Because appearance and disappearance are two halves of one system, the verbs pair up. 多了 (duō le) "there's one extra" is the appearance side; 少了 (shǎo le) "there's one short" is the disappearance side — and both push the counted noun to the end.
桌上多了一把椅子，是谁搬来的？
zhuō shàng duō le yì bǎ yǐzi, shì shéi bān lái de?
There's an extra chair at the table — who brought it? (informal) — 多了 = appearance.
怎么少了一个人？我们再数一遍。
zěnme shǎo le yí gè rén? wǒmen zài shǔ yí biàn
How are we one person short? Let's count again. (informal) — 少了 = disappearance.
A possessor can head the clause
The setting up front isn't always a place — it's often the person who suffered the loss, the owner or experiencer. Even then, the thing that went missing stays indefinite and still trails the verb. This is how you naturally say "I lost a…":
我上个月丢了一部手机。
wǒ shàng gè yuè diū le yí bù shǒujī
I lost a phone last month. (informal) — 我 is the affected owner, but 一部手机 is still indefinite and post-verb.
他们家出了一点事，这几天都没来。
tāmen jiā chū le yìdiǎn shì, zhè jǐ tiān dōu méi lái
Something came up in their family, so they haven't been around these few days. (informal) — 出了一点事 = 'a bit of trouble arose'.
Watch the difference between the indefinite presentative and a definite loss. 我丢了一个钱包 "I lost a wallet" presents a new, indefinite thing after the verb. But 我把钱包丢了 "I lost my wallet" treats the wallet as a definite, known object being disposed of — a completely different construction, and the reason 把 and the presentative can't be mixed.
Why not 把, and why not a definite subject
Two temptations from English (and from over-eager grammar rules) both fail here.
First, 不能用把. The 把 construction needs an agent who disposes of a definite object — 我把鱼杀了 "I killed the fish." But disappearance presentatives have no agent and an indefinite noun, so 把 is structurally impossible: you can't dispose of something that has no disposer and isn't even definite yet.
Second, a definite subject is a different sentence entirely. 那条鱼死了 "that fish died" is a plain statement about a fish you both already know — it's not a presentative. It comments on a known topic; it doesn't present something onto/off the scene. The contrast is the whole point:
| Sentence | What it is |
|---|---|
| 死了一条鱼 | presentative — a fish (indefinite, new to the talk) died |
| 那条鱼死了 | plain statement — that (known) fish died |
Common Mistakes
1. Fronting the indefinite as the subject. A newly-presented "a fish died" goes verb-first; 一条鱼 up front reads as counting or definite.
❌ 一条鱼死了。
Off for presenting a loss — this reads as 'the one fish died', a definite/counting sense.
✅ 死了一条鱼。
sǐ le yì tiáo yú
A fish died. — the affected thing, indefinite, follows the verb.
2. Forcing it into a 把 sentence. No agent, indefinite noun → 把 can't apply.
❌ 家里把一辆自行车丢了。
Wrong — 把 needs an agent and a definite object; a presentative loss has neither.
✅ 家里丢了一辆自行车。
jiā lǐ diū le yí liàng zìxíngchē
A bicycle went missing from home. — plain presentative order.
3. Dropping 了. The event needs 了 to register that the scene has changed.
❌ 鱼缸里死一条鱼。
Incomplete — without 了 there's no completed event: 鱼缸里死了一条鱼.
✅ 鱼缸里死了一条鱼。
yúgāng lǐ sǐ le yì tiáo yú
A fish died in the tank. — V + 了 + indefinite noun.
4. Making the vanished thing definite in the presentative slot. A known "that goldfish" is a topic, not a presented item.
❌ 死了那条金鱼。
Odd — a known 'that goldfish' should lead: 那条金鱼死了.
✅ 那条金鱼死了。
nà tiáo jīnyú sǐ le
That goldfish died. — definite thing → subject-first statement.
Key Takeaways
- Disappearance is the mirror of appearance: both use V + 了 + indefinite noun, so the affected thing follows the verb — 丢了一个钱包, 死了一条鱼, 少了一个人.
- The verbs are intransitive change-of-state ones (死, 丢, 少, 跑, 走, 塌); the post-verb noun undergoes the change, it isn't an object acted on.
- The system is symmetric: 多了 (one extra, appearance) vs 少了 (one short, disappearance), both counting-noun-last.
- Never 把 — there's no agent and the noun is indefinite; 把 is structurally impossible here.
- A definite subject makes it a plain statement instead: 那条鱼死了 ≠ 死了一条鱼.

- Presentative Sentences: Something AppearsHSK 4 — When something new appears or happens, Chinese puts the indefinite noun AFTER the verb: 来了一个人 'someone came', 前面走过来一个警察 'a policeman came walking up ahead', 下雨了 'it started raining'. English keeps the subject first ('a person came'), but Chinese sends the new, indefinite participant to the end — because new information goes late — usually with 了.
- Existence with 有 (There Is/Are)HSK 1 — 'There is/are' is a location-first frame: Place + 有 + (Number-MW) + indefinite Noun — 桌子上有一本书 'there's a book on the table', 前面有一家商店 'there's a shop up ahead'; the new thing is indefinite and comes last.
- The Perfective 了 (le₁): Completed ActionHSK 1 — The verb-suffix 了 (le₁) sits right after the verb and marks the action as completed or realized — 我吃了饭, 买了三本书. It is completion aspect, not past tense, so it can even point to the future: 下了课就走.
