条 (tiáo) is the measure word for things shaped like a long, thin strip — especially ones that are flexible, that bend or wind. Its prototype is a length of something: a fish, a road, a river, a snake, a pair of trousers, a scarf. English again has a loose parallel in "a strip of," "a length of," "a stretch of" — but where English reserves those for a few nouns, Chinese uses 条 as a full category for anything elongated and pliable. The core image is a 1-D line: not a flat plane (that's 张), not a 3-D lump (that's 个), but a stretched-out length.
The long-and-thin image
The membership feels random until you picture each noun as a strip or a line. Then it clicks:
| Noun | With 条 | Meaning |
|---|---|---|
| 鱼 (yú) | 一条鱼 (yì tiáo yú) | a fish |
| 路 (lù) | 一条路 (yì tiáo lù) | a road |
| 河 (hé) | 一条河 (yì tiáo hé) | a river |
| 裤子 (kùzi) | 一条裤子 (yì tiáo kùzi) | a pair of trousers |
| 裙子 (qúnzi) | 一条裙子 (yì tiáo qúnzi) | a skirt |
| 围巾 (wéijīn) | 一条围巾 (yì tiáo wéijīn) | a scarf |
| 蛇 (shé) | 一条蛇 (yì tiáo shé) | a snake |
| 腿 (tuǐ) | 一条腿 (yì tiáo tuǐ) | a leg |
Trousers and skirts are the case that surprises learners most. In English "a pair of trousers" is grammatically plural, but Chinese sees the single garment as one elongated tube of cloth — 一条裤子, one strip. The same logic makes a scarf, a towel (一条毛巾, yì tiáo máojīn) and a tie (一条领带, yì tiáo lǐngdài) all 条.
河里有一条大鱼，你看见了吗？
hé li yǒu yì tiáo dà yú, nǐ kànjiàn le ma?
There's a big fish in the river — did you see it? (informal) — fish take 条.
这条路一直往前，走到头就是车站。
zhè tiáo lù yìzhí wǎng qián, zǒu dào tóu jiù shì chēzhàn
This road goes straight ahead; the station is right at the end. (informal) — roads are long, winding lines: 条.
天冷了，给你买了一条围巾。
tiān lěng le, gěi nǐ mǎi le yì tiáo wéijīn
It's turned cold — I bought you a scarf. (informal) — a scarf is a long strip of cloth: 条.
Abstract "strips": news, messages, rules
条 extends beautifully from physical strips to items that come in a linear string — a single piece of news, a text message, a rule, a comment. Think of each as one line of information:
我刚看到一条很重要的新闻。
wǒ gāng kàndào yì tiáo hěn zhòngyào de xīnwén
I just saw an important piece of news. (neutral) — a news item is one linear entry: 条.
他给我发了三条短信，我都没回。
tā gěi wǒ fā le sān tiáo duǎnxìn, wǒ dōu méi huí
He sent me three texts and I didn't reply to any of them. (informal) — text messages come one line at a time: 条.
This is where 条 stops being about literal shape and becomes about discrete linear items in a stream — messages, notifications, dictionary entries (一条 in a dictionary), regulations (一条规定, yì tiáo guīdìng). A related fixed expression is 一条命 (yì tiáo mìng, "a life"), as in saving someone's life — the thread of a life, counted as a single strand.
The animal overlap: dogs and fish
Here is the honest complication. Most animals take 只 (zhī — see 只 for animals), but a few elongated ones conventionally take 条: fish (一条鱼) and snakes (一条蛇) essentially always take 条, never 只. Dogs sit on the fence — you'll hear both 一条狗 (emphasising the long body) and 一只狗 (the general animal classifier), with 只 more common in everyday speech across the mainland:
邻居家养了一条大狗，特别凶。
línjū jiā yǎng le yì tiáo dà gǒu, tèbié xiōng
The neighbours keep a big dog — it's really fierce. (informal) — 条 highlights the dog's long body; 一只狗 is equally fine.
草丛里有一条蛇，别过去！
cǎocóng li yǒu yì tiáo shé, bié guòqù!
There's a snake in the grass — don't go over there! (informal) — snakes are always 条, never 只.
There's no rule that will let you predict which animals defect from 只 to 条; you learn that fish and snakes are firmly 条, dogs go either way, and everything else (cats, birds, rabbits) is 只. Trust the shape image — the more snake-like the animal, the more 条 fits.
Contrast with 个
As always, 个 (ge) is the fallback that beginners overuse. For 条 nouns it's understood but noticeably flat, and for fish and roads it sounds plainly wrong to a native ear. Keep the three-way image separation clear:
| Object | Right classifier | Shape |
|---|---|---|
| 一条河 (a river) | 条 | long, winding line |
| 一张纸 (a sheet of paper) | 张 | flat plane |
| 一本书 (a book) | 本 | bound thick volume |
| 一个苹果 (an apple) | 个 | compact 3-D lump |
桌上放着一条黄瓜和一个西红柿。
zhuō shang fàng zhe yì tiáo huángguā hé yí ge xīhóngshì
There's a cucumber and a tomato on the table. (neutral) — long cucumber → 条, round tomato → 个: the shape drives the choice.
Common Mistakes
1. Defaulting to 个 for long-thin things. Fish, roads and rivers take 条; 个 sounds wrong here, not merely unpolished.
❌ 我钓到了一个鱼。
Incorrect — a fish is elongated: 一条鱼.
✅ 我钓到了一条鱼。
wǒ diào dào le yì tiáo yú
I caught a fish. — 条 for the elongated fish.
2. Treating 裤子 as plural like English 'trousers'. One pair of trousers is a single 条, not "two."
❌ 我买了两条裤子。（meaning one pair）
Mismatch — one pair of trousers is 一条裤子; 两条 means two separate pairs.
✅ 我买了一条裤子。
wǒ mǎi le yì tiáo kùzi
I bought a pair of trousers. — one garment = 一条.
3. Using 只 for a fish or a snake. Fish and snakes are firmly 条; only most other animals are 只.
❌ 鱼缸里有三只鱼。
Incorrect — fish take 条: 三条鱼.
✅ 鱼缸里有三条鱼。
yúgāng li yǒu sān tiáo yú
There are three fish in the tank. — 条 for fish.
4. Using 二 instead of 两 before 条. For "two" in front of a measure word, use 两, never 二.
❌ 二条河
Incorrect — before a measure word 'two' is 两, not 二.
✅ 两条河
liǎng tiáo hé
two rivers — 两条, not 二条.
Key Takeaways
- 条 (tiáo) classifies long, thin, flexible or winding things: 鱼 (fish), 路 (roads), 河 (rivers), 蛇 (snakes), 裤子 (trousers), 裙子 (skirts), 围巾 (scarves), 腿 (legs).
- A pair of trousers is one elongated garment — 一条裤子, singular, not "a pair."
- It extends to linear items in a stream: 一条新闻 (a news item), 三条短信 (three texts), 一条规定 (a rule).
- Among animals, fish and snakes are firmly 条; dogs take either 条 or 只; most other animals are 只.
- Contrast the shapes: line → 条, flat plane → 张, bound volume → 本, compact lump → 个; and use 两, not 二, for "two."

- 只 (Animals & One of a Pair)HSK 1 — 只 (zhī) is the default measure word for most animals and for one member of a natural pair: 一只猫 (a cat), 三只鸟 (three birds), 一只手 (one hand), 一只鞋 (one shoe of a pair). Read it zhī, not zhǐ.
- 张 (Flat Objects)HSK 1 — 张 (zhāng) is the measure word for things with a flat surface — paper, tickets, maps, photos, tables and beds all share the flat-top image that groups them: 一张纸, 两张票, 一张桌子.
- Choosing the Right ClassifierHSK 2 — A decision procedure for picking the right Chinese measure word: default to 个 when stuck, otherwise match the noun by shape, category, or the respect it deserves — plus a reference table of the ~15 classifiers that cover most everyday nouns.
- The Default 个HSK 1 — 个 (gè, usually neutral-toned ge) is the general-purpose measure word — the safe fallback when you don't know the specific classifier — and it correctly covers people, many everyday objects, and abstract nouns; the goal is to graduate to specific classifiers while keeping 个 for the nouns that genuinely take it.
