When do I use 反而 vs 却?

Use 反而 when the outcome is the opposite of what the context leads you to expect, often after a negative statement or in a ‘not only… but on the contrary’ pattern. Use 却 for a milder contrast that does not involve a reversal of expectation—simply ‘yet’ or ‘however’.

Can 反而 and 却 be used interchangeably?

Only in very limited cases where the contrast is both mild and perceived as a reversal (e.g., ‘He didn't come, (but/nstead) he called’). In most situations, they are not interchangeable: 反而 emphasizes a strong opposite, while 却 is a general adversative.

What structure does 反而 commonly appear in?

反而 often follows a clause with 不但不/没 (not only not…) or a negative expectation. For example: 他不但不帮忙，反而添乱 (Not only did he not help, but he made trouble instead). It can also appear alone after a context that implies a certain expectation.

Can I use 却 together with 但/但是?

Yes. 但/却 is a common combination to reinforce the contrast: e.g., 他很有钱，但却不快乐 (He is rich, yet he is not happy). This pattern is very natural.

反而 vs 却 (fǎn'ér vs què): two adverbs of counter‑expectation

反而 and 却 both introduce a contrast, but with a key difference: 反而 highlights an outcome that is the opposite of what the context implies (a strong reversal), while 却 simply marks a mild adversative or concessive contrast (≈ “yet” or “however”). 反而 is typically used when the result defies a negative expectation, whereas 却 can be used in a wider range of oppositional contexts without implying surprise.

Both 反而 and 却 are pre‑verbal adverbs that express contrast. The crucial distinction lies in the strength and direction of the contrast: 反而 signals that the actual result is the reverse of what was expected, often after a negative premise (e.g., “not only… but on the contrary…”). 却, on the other hand, merely sets up a contrary or surprising element without requiring a specific expectation; it is closer to English “yet” or “however” and can appear in simple adversative contexts. In sentences where the contrast is purely concessive (e.g., “I wanted to go, but it rained”), 却 is natural, while 反而 would sound odd unless the rain was explicitly counter to an expectation.

Когда что использовать

反而fǎn ér

on the contrary; instead

Use 反而 when a result is the opposite of what the preceding context leads you to expect. It often follows a negative statement or a disappointed expectation, especially in the pattern “不但不/没…反而…” (not only not…, but on the contrary…). It emphasizes that the actual outcome reverses the anticipated direction.

反而 cannot be used for a simple concession or unexpected fact that is not a direct reversal of a contextual expectation. It also carries a stronger, more emphatic tone than 却.

却què

yet; but; however

Use 却 to introduce a mild contrast, concession, or unexpected element. It can be placed before any verb to create an adversative reading, and it works in both “topic‑comment” and parallel structures. 却 is more flexible and common than 反而, and it does not require that the contrast be a reversal of expectation.

却 can be combined with 但/但是 for extra emphasis (但…却…), and it is often used to contrast two attributes or actions within the same person or situation. It is less dramatic than 反而.

Degree of reversal	Strong opposite outcome (reversal of expectation)	Mild contrast / adversative (no reversal required)
Typical syntactic context	Often follows a negative clause (e.g., 不但不/没…反而…)	Can follow any clause, including positive statements

Примеры

反而
他不但没道歉，反而骂了我一顿。
Tā bú dàn méi dào qiàn, fǎn ér mà le wǒ yí dùn.
Not only did he not apologize, but he scolded me instead.
Outcome reverses the expected apology → 反而 required.
却
大家都以为他会赢，他却输了。
Dà jiā dōu yǐ wéi tā huì yíng, tā què shū le.
Everyone thought he would win, yet he lost.
Simple unexpected contrast (losing is contrary to opinion, but not a reversal of an implied opposite expectation).
反而
我劝他休息，他反而工作得更起劲了。
Wǒ quàn tā xiū xi, tā fǎn ér gōng zuò dé gèng qǐ jìn le.
I advised him to rest, but he worked even harder instead.
Outcome is opposite to advice → 反而.
却
他很努力，成绩却不理想。
Tā hěn nǔ lì, chéng jì què bù lǐ xiǎng.
He works hard, yet his results are not ideal.
Mild adversative: hard work vs. poor results. Using 反而 here would be unnatural because the contrast is not a direct reversal of a specific expectation.
反而
病情不但没有好转，反而恶化了。
Bìng qíng bú dàn méi yǒu hǎo zhuǎn, fǎn ér è huà le.
Not only did the condition not improve, but it worsened on the contrary.
Classic 不但不…反而… structure.
却
我邀请了他，他却没来。
Wǒ yāo qǐng le tā, tā què méi lái.
I invited him, yet he didn't come.
Simple concession; no implied opposite expectation.

Частые ошибки

Using 却 where a strong reversal is needed: ‘我劝他休息，他却工作得更起劲了’ is weak; use 反而 to show the opposite action.
Using 反而 for a simple concession like ‘他很努力，反而成绩不理想’ — this sounds forced because 反而 implies a direct reversal of an expectation that is not present.
Omitting the negative premise before 反而: ‘今天下雨，反而我带了伞’ should be ‘今天下雨，我反而带了伞’ (but even then it may be unnatural without an explicit expectation).
Overusing 却 in contexts where no contrast is intended (e.g., mere sequence).
