Don't Calque: English Idioms in Chinese | Chinese (Mandarin) Grammar

Idioms are the last thing you should translate word-for-word, and the first thing learners try to. Tell a Chinese friend it's "raining cats and dogs" rendered literally — 天上下猫和狗 — and you'll get a baffled stare, not a laugh. Idioms are culture-bound packages: the words are a frozen picture, and the picture only means something inside its own language. This page teaches an anti-pattern, the thing not to do — don't calque (translate literally) — and gives you the correct instinct instead: translate the meaning, reach for a native Chinese idiom only when one genuinely lines up, and when in doubt, drop the idiom and say the point plainly. Plain Chinese always beats a broken idiom. It pairs with what chengyu are and the colloquial 惯用语.

Three outcomes, not one

When you want to say an English idiom in Chinese, exactly one of three things is true. Sorting your idiom into the right bucket is the whole skill:

Bucket	What to do	Example
A genuine native match exists	use the Chinese idiom	kill two birds → 一箭双雕
No idiom, but a plain phrase works	say it plainly	raining cats and dogs → 下大雨
The concept doesn't transfer at all	rephrase the intent	break a leg → 祝你好运 / 加油

Bucket A: idioms that really do match

A satisfying number of English idioms have a native Chinese cousin — usually a four-character chengyu — that carries the same sense. These are safe to use and make you sound fluent:

English idiom	Chinese	Pinyin
kill two birds with one stone	一箭双雕 / 一举两得	yí jiàn shuāng diāo / yìjǔ liǎngdé
add fuel to the fire	火上浇油	huǒ shàng jiāo yóu
a piece of cake	小菜一碟	xiǎocài yì dié
the tip of the iceberg	冰山一角	bīngshān yìjiǎo
when pigs fly	太阳从西边出来	tàiyáng cóng xībiān chūlái

坐地铁上班又省钱又不堵车，一举两得。

zuò dìtiě shàngbān yòu shěngqián yòu bù dǔchē, yìjǔ liǎngdé.

Taking the subway to work saves money and dodges the traffic — two birds with one stone. (neutral) — a genuine match, used as a summing-up.

这次考试对他来说就是小菜一碟。

zhè cì kǎoshì duì tā lái shuō jiùshì xiǎocài yì dié.

This exam was a piece of cake for him. (informal) — 小菜一碟, never a literal cake.

你说他会主动道歉？太阳从西边出来了吧！

nǐ shuō tā huì zhǔdòng dàoqiàn? tàiyáng cóng xībiān chūlái le ba!

You think HE'll apologize first? When pigs fly! (informal) — the native 'when the sun rises in the west.'

💡

Even inside Bucket A, verify the match before you lean on it. "Two birds, one stone" is idiomatically 一箭双雕 ("one arrow, two hawks") in native usage; the widely-seen 一石二鸟 ("one stone, two birds") is actually a loan-translation of the English — understood everywhere, but not the traditional idiom. A "perfect equivalent" is sometimes a calque wearing a chengyu's clothes.

Bucket B: no idiom — just say it plainly

Most everyday English idioms have no Chinese idiom behind them, and the correct translation is the plain literal meaning. "It's raining cats and dogs" is simply 下大雨 (heavy rain) or 下倾盆大雨 (torrential rain). "It cost an arm and a leg" is 贵得要命 (crazy expensive). Chasing a colourful idiom here only produces nonsense.

English idiom	Say plainly	Pinyin
raining cats and dogs	下大雨 / 下倾盆大雨	xià dàyǔ / xià qīngpén dàyǔ
cost an arm and a leg	贵得要命 / 特别贵	guì de yàomìng / tèbié guì
under the weather	不太舒服	bú tài shūfu
the ball's in your court	看你的了	kàn nǐ de le
spill the beans	说漏嘴 / 走漏风声	shuō lòu zuǐ / zǒulòu fēngshēng

今天下大雨，你出门带把伞吧。

jīntiān xià dàyǔ, nǐ chūmén dài bǎ sǎn ba.

It's pouring today — take an umbrella when you go out. (neutral) — plain 下大雨 for 'raining cats and dogs.'

这个包太贵了，贵得要命，我可买不起。

zhège bāo tài guì le, guì de yàomìng, wǒ kě mǎi bù qǐ.

This bag is insanely expensive — cost an arm and a leg — no way I can afford it. (informal) — the meaning, plainly stated.

他不小心说漏嘴，把惊喜派对的事说出去了。

tā bù xiǎoxīn shuō lòu zuǐ, bǎ jīngxǐ pàiduì de shì shuō chūqù le.

He accidentally let it slip and gave away the surprise party. (informal) — 说漏嘴 'spill the beans,' no beans in sight.

Bucket C: the concept doesn't transfer — rephrase the intent

Some idioms encode a cultural act with no Chinese counterpart. "Break a leg" is the killer example: theatre superstition is Western, and a literal 断条腿 (break a leg) would horrify a Chinese listener. What you actually mean is "good luck," so you say 祝你好运 (zhù nǐ hǎoyùn) or, for encouragement before an effort, 加油 (jiāyóu). Translate the intent, not the image.

马上就要上台了，加油，别紧张！

mǎshàng jiù yào shàngtái le, jiāyóu, bié jǐnzhāng!

You're on stage any second — you've got this, don't be nervous! (informal) — 加油 carries the 'break a leg' intent.

明天面试，祝你好运，我相信你没问题的。

míngtiān miànshì, zhù nǐ hǎoyùn, wǒ xiāngxìn nǐ méi wèntí de.

Your interview's tomorrow — good luck, I'm sure you'll be fine. (neutral) — 'break a leg' → the plain wish 祝你好运.

💡

Here is a delightful reverse case. A few "idioms" line up perfectly because English borrowed them from Chinese: 好久不见 (hǎojiǔ bújiàn) is the source of "long time no see," 丢脸 / 丢面子 (diū liǎn) gave English "lose face," and 纸老虎 (zhǐ lǎohǔ) is the original "paper tiger." Even 加油 has now entered English dictionaries as "add oil." When the borrowing ran English←Chinese, calquing works — because it already happened.

The rule of thumb

When you're unsure which bucket an idiom lands in, default to Bucket B: state the meaning plainly. A clear plain sentence is always correct; a mangled literal idiom is always wrong and often incomprehensible. Reach for a chengyu only when you can confidently name a real one that fits — and if you're building that instinct, the wisdom chengyu that map onto English proverbs are the friendliest place to start. It is far better to sound simple and clear than clever and broken.

Common Mistakes

1. Calquing the image word-for-word. The literal picture rarely survives translation.

❌ 外面下猫和狗。

Meaningless in Chinese — 'raining cats and dogs' is just 下大雨.

✅ 外面下大雨呢，别出去了。

wàimiàn xià dàyǔ ne, bié chūqù le.

It's pouring outside — don't go out. — the plain, correct rendering.

2. Literal 'break a leg.' A Western theatre superstition; the literal Chinese is alarming.

❌ 祝你摔断一条腿！

Horrifying, not encouraging — the intent is 'good luck': 祝你好运 / 加油.

✅ 祝你演出成功，加油！

zhù nǐ yǎnchū chénggōng, jiāyóu!

Break a leg — hope the show goes great! — the intent, rephrased.

3. Literal 'piece of cake.' 一块蛋糕 is a real slice of cake, with zero idiomatic sense.

❌ 这个太简单了，就是一块蛋糕。

Wrong — that's a literal slice of cake; the idiom is 小菜一碟.

✅ 这个太简单了，简直是小菜一碟。

zhège tài jiǎndān le, jiǎnzhí shì xiǎocài yì dié.

This is so easy, it's an absolute piece of cake. — the native idiom.

4. Trusting a loan-translation as the 'real' idiom. 一石二鸟 is a calque; the native chengyu is 一箭双雕.

❌ 认为每个英语成语都有一个一模一样的中文双胞胎

Not so — verify; the native idiom is often different (一箭双雕, not just 一石二鸟).

✅ 一举两得。

yìjǔ liǎngdé.

to achieve two things at once — a safe, thoroughly native option.

Key Takeaways

Don't calque. Word-for-word idiom translation produces baffling Chinese (天上下猫和狗).
Sort every idiom into three buckets: native match (一箭双雕), say it plainly (下大雨), or rephrase the intent (break a leg → 加油).
Even real matches need checking — some "equivalents" are loan-translations (一石二鸟) rather than the native idiom (一箭双雕).
Default to plain speech when unsure. A clear plain sentence always beats a mangled idiom.
A few line up because English borrowed from Chinese: 好久不见 ("long time no see"), 丢脸 ("lose face"), 纸老虎 ("paper tiger").
