无效
When something is 无效 (wú xiào), it means it doesn't work or achieve the desired result. Think of it like a plan that just doesn't get the job done.
For example, if you try to fix a leaky faucet with tape, that might be 无效 because the tape won't stop the water. Or, if you have a rule that no one follows, that rule is 无效. It's about a lack of effect or success.
When something is 无效 (wú xiào), it means it doesn't work as intended or doesn't produce the desired result. Think of it like trying to use a broken tool – it's ineffective because it won't get the job done.
For example, if you're studying for a test but the method you're using isn't helping you remember anything, you could say that method is 无效. Or, if a medicine doesn't make you feel better, then it's 无效 in treating your illness.
When something is 无效 (wúxiào), it means it doesn't produce the desired or intended result; it's ineffective. Think of a plan that doesn't work out, or a medicine that fails to cure an illness – both would be described as 无效. It can also refer to something that is no longer valid, like an expired coupon or a canceled contract. The key idea is a lack of efficacy or validity.
When something is 无效 (wú xiào), it means it doesn't produce the desired or intended result; it's ineffective. Think of a method or an effort that simply doesn't work as hoped.
For example, if you try a new study technique but your grades don't improve, you could say that technique was 无效 (wú xiào). It implies a lack of efficacy or a failure to achieve the intended purpose. So, if a solution is tried and doesn't fix the problem, it is 无效 (wú xiào).
When something is 无效 (wúxiào), it means it's not working as intended or producing the desired result. Think of it as being 'ineffective' or 'invalid'.
For example, if a method doesn't solve a problem, you can say it's 无效. Or, if a contract is no longer legally binding, it is 无效.
It can also describe something that has been canceled or made void. The key idea is a lack of efficacy or legal standing.
无效 30 सेकंड में
- 无效 (wúxiào) means ineffective.
- Use it to describe something that doesn't work.
- It's a common adjective in daily Chinese.
§ Basic Usage of 无效
无效 (wú xiào) is an adjective, and it directly translates to 'ineffective' or 'invalid'. This means it describes a noun. Think of it like 'bad' or 'good' but for effectiveness or validity.
- DEFINITION
- 无效 (wú xiào): ineffective, invalid
The most straightforward way to use 无效 is to put it directly before the noun it modifies, just like in English.
这是一个无效的合同。(Zhè shì yīgè wúxiào de hétong.)
This sentence means: This is an invalid contract. Here, 无效 modifies 合同 (hétong), which means contract.
这个方法是无效的。(Zhège fāngfǎ shì wúxiào de.)
This means: This method is ineffective. Here, 无效 describes 方法 (fāngfǎ), meaning method.
§ Using 无效 with '变得' (biàn de) and '使' (shǐ)
You can also use 无效 with verbs that indicate a change of state, like 变得 (biàn de), meaning 'to become', or 使 (shǐ), meaning 'to make/cause'.
变得无效 (biàn de wú xiào) - to become ineffective/invalid
他的努力最终变得无效。(Tā de nǔlì zuìzhōng biàn de wúxiào.)
This translates to: His efforts eventually became ineffective.
使...无效 (shǐ... wú xiào) - to make/render... ineffective/invalid
这个规定使所有旧证书无效。(Zhège guīdìng shǐ suǒyǒu jiù zhèngshū wúxiào.)
This means: This regulation renders all old certificates invalid.
§ 无效 as a Result of an Action
Sometimes, 无效 can appear after a verb to describe the outcome or result of an action. This is a common structure in Chinese where the adjective acts as a result complement.
投票结果被宣布无效。(Tóupiào jiéguǒ bèi xuānbù wúxiào.)
This translates to: The voting results were declared invalid. Here, 无效 is the result of being declared.
他的签证过期了，所以现在无效。(Tā de qiānzhèng guòqī le, suǒyǐ xiànzài wúxiào.)
This means: His visa expired, so it is now invalid.
§ Common Phrases and Prepositions with 无效
While 无效 doesn't typically take prepositions in the same way English 'ineffective' might (e.g., 'ineffective *for* something'), it's often used in contexts that imply a lack of effect *on* something.
对...无效 (duì... wú xiào) - ineffective against/for...
This structure uses 对 (duì), which often means 'to' or 'for', to indicate what something is ineffective against or for.
这种药对感冒无效。(Zhè zhǒng yào duì gǎnmào wúxiào.)
This means: This medicine is ineffective against the common cold.
§ Mistakes people make with 无效
When learning Chinese, especially with words that seem straightforward, it's easy to fall into common traps. Let's look at how to avoid misusing 无效 (wú xiào).
§ Mistake 1: Using it as a verb meaning 'to make ineffective'
A common mistake is to think 无效 can be used like an English verb 'to invalidate' or 'to make ineffective'. In Chinese, you need a verb to express this action.
- Wrong Example
- 我们无效了合同。 (Wǒmen wúxiào le hétong.)
This literally translates to 'We ineffective-ed the contract,' which doesn't make sense. Instead, you need to use verbs like 使 (shǐ - to make/cause), 宣布 (xuānbù - to declare), or 认定 (rèndìng - to determine/recognize) in conjunction with 无效.
- Correct Usage
- 我们可以宣布这份合同无效。
我们可以宣布这份合同无效。(Wǒmen kěyǐ xuānbù zhè fèn hétong wúxiào.) (We can declare this contract invalid.)
- Correct Usage
- 这种方法被证明是无效的。
这种方法被证明是无效的。(Zhè zhǒng fāngfǎ bèi zhèngmíng shì wúxiào de.) (This method was proven to be ineffective.)
§ Mistake 2: Confusing it with 'useless' or 'no use'
While 'ineffective' can sometimes imply 'useless,' 无效 specifically means something didn't achieve its intended effect or is no longer valid. It's not a general term for something being 'bad' or 'of no value' in every context.
- Wrong Example
- 这个旧手机是无效的。
While an old phone might not work well, saying it's 'invalid' isn't the most natural fit. You'd likely use 没用 (méiyòng - useless) or 坏了 (huài le - broken).
- Correct Usage (for something not working)
- 这个旧手机没用了。
这个旧手机没用了。(Zhège jiù shǒujī méiyòng le.) (This old phone is useless now.)
§ Mistake 3: Forgetting the context of 'validity'
无效 is very often used in contexts of legality, agreements, tickets, or official documents where something loses its validity or never had it in the first place.
- Example Contexts
- 合同无效 (hétong wúxiào) - contract invalid
- 票据无效 (piàojù wúxiào) - ticket invalid
- 签证无效 (qiānzhèng wúxiào) - visa invalid
- 投票无效 (tóupiào wúxiào) - vote invalid
§ Practice makes perfect
The best way to get it right is to expose yourself to how native speakers use it. Pay attention to the sentences where 无效 appears and try to internalize the patterns. Don't be afraid to make mistakes; that's how you learn!
How Formal Is It?
"此合約已被宣告無效。 (Cǐ héyuē yǐ bèi xuāngào wúxiào.) This contract has been declared invalid."
"這個方法沒用。 (Zhège fāngfǎ méi yòng.) This method is ineffective."
"說什麼都白搭。 (Shuō shénme dōu báidā.) Whatever you say is useless."
"這個玩具不好用。 (Zhège wánjù bù hǎo yòng.) This toy is no good (ineffective)."
"這機器廢了。 (Zhè jīqì fèi le.) This machine is kaput (useless)."
रोचक तथ्य
The character 效 (xiào) is also found in words like 有效 (yǒu xiào), meaning 'effective', and 效率 (xiào lǜ), meaning 'efficiency'.

Both '无效' and '徒劳' can describe something that doesn't achieve its intended result. However, '徒劳' specifically emphasizes the wasted effort involved, often implying a sense of futility or pointlessness.
'无效' simply means 'ineffective' or 'invalid' without necessarily focusing on the effort. '徒劳' means 'futile' or 'in vain,' highlighting that the effort put in was wasted.
他的所有努力都徒劳无功。(tā de suǒyǒu nǔlì dōu túláo wúgōng.) - All his efforts were in vain.
Both mean 'useless' or 'ineffective.' '没用' is more colloquial and can be used for both objects and actions, often carrying a stronger negative connotation of being completely without value or function.
'无效' is more formal and specific to a lack of desired effect or validity. '没用' is a broader term for 'useless' or 'no good' in general.
这个计划没用，我们得想别的办法。(zhège jìhuà méiyòng, wǒmen děi xiǎng bié de bànfǎ.) - This plan is useless, we need to think of another way.
Both relate to a lack of effectiveness. '失效' specifically refers to something that has become ineffective or invalid due to an expiration or a change in conditions.
'无效' can describe something that was never effective or is currently ineffective. '失效' implies that something *was* effective but no longer is.
合同已经失效了。(hé tóng yǐjīng shīxiào le.) - The contract has expired/is no longer valid.
Similar to '没用,' '无用' also means 'useless' or 'of no use.' It's slightly more formal than '没用' but less formal than '无效' when discussing effectiveness.
'无效' focuses on the lack of the desired effect or validity. '无用' focuses on the lack of practical value or utility.
这些旧文件对他来说已经无用。(zhèxiē jiù wénjiàn duì tā lái shuō yǐjīng wúyòng.) - These old documents are useless to him.
This phrase directly means 'doesn't work' or 'has no effect,' which is very close to 'ineffective.'
'无效' is a single adjective describing a state. '不起作用' is a verb phrase describing an action or lack thereof, often used for medicine or methods.
这种药对我的头痛不起作用。(zhè zhǒng yào duì wǒ de tóutòng bù qǐ zuòyòng.) - This medicine has no effect on my headache.

इसे कैसे इस्तेमाल करें
无效 (wú xiào) means 'ineffective' or 'invalid'. It describes something that does not produce the desired effect or is legally null and void. You can use it to describe plans, methods, contracts, or even medicine.
A common mistake is to confuse 无效 with 没有用 (méi yǒu yòng), which means 'useless'. While there's overlap, 无效 specifically implies a failure to achieve a goal or a lack of legal standing, whereas 没有用 is a more general term for something without utility. For example, a medicine might be 无效 if it doesn't cure the illness, but a broken umbrella might be 没有用.
सुझाव
Basic Meaning of 无效
无效 (wú xiào) literally means 'without effect' or 'no result'. It's used to describe something that does not achieve its intended purpose or has no legal force. Think of it as the opposite of 'effective' or 'valid'.
无效 vs. 没有用
While 无效 and 没有用 (méi yǒu yòng - useless) can sometimes overlap, 无效 often implies a *failed attempt* or *lack of legal standing*, whereas 没有用 is more generally about something being *of no practical use*.
Common Usage: Agreements
You'll frequently hear 无效 used in legal or official contexts. For example, 合同无效 (hé tóng wú xiào) means the 'contract is invalid'.
Common Usage: Efforts
When your efforts don't produce results, you can say 努力无效 (nǔ lì wú xiào), meaning 'efforts are ineffective' or 'efforts are futile'.
Common Usage: Methods
If a method or approach doesn't work, you can describe it as 这种方法无效 (zhè zhǒng fāng fǎ wú xiào), meaning 'this method is ineffective'.
搭配 (Collocations) with 无效
Remember some common phrases:
• 无效投票 (wú xiào tóu piào) - invalid vote
• 无效期 (wú xiào qī) - invalid period / expiration date
• 宣告无效 (xuān gào wú xiào) - declare invalid
Don't confuse with 'wrong'
无效 is about something not working or not being valid. It's not the same as 错 (cuò - wrong) or 错误 (cuò wù - mistake), which refer to being incorrect.
Sentence Structure
无效 usually functions as an adjective, often appearing after the noun it modifies or as a predicate.
• 他的解释无效。(Tā de jiě shì wú xiào.) - His explanation is ineffective.
• 这张票已经无效了。(Zhè zhāng piào yǐ jīng wú xiào le.) - This ticket is already invalid.
Think of English equivalents
When you encounter 无效, try to think of English words like 'invalid', 'ineffective', 'void', or 'futile'. This helps solidify its meaning.
Practice with examples
Write down a few sentences using 无效 in different contexts.
• 这个药对我的病无效。(Zhège yào duì wǒ de bìng wú xiào.) - This medicine is ineffective for my illness.
• 所有的努力都无效。(Suǒ yǒu de nǔ lì dōu wú xiào.) - All efforts were ineffective.
शब्द की उत्पत्ति
无效 (wú xiào) is composed of two characters: 无 (wú) meaning 'without' or 'no', and 效 (xiào) meaning 'effect' or 'result'.
मूल अर्थ: The original meaning directly combines to 'without effect' or 'no result'.
Sino-Tibetanसांस्कृतिक संदर्भ

अक्सर पूछे जाने वाले सवाल
10 सवालThat's a great question! '无效' (wúxiào) specifically means 'ineffective' or 'invalid.' Think of it as something that doesn't produce the desired result or is no longer legally binding. Other words like '没用' (méiyòng) are more general for 'useless' or 'no use,' and can apply to things that simply have no value or purpose. '无效' is more about the function or validity of something.
Generally, no. '无效' is typically used for things, actions, or processes. You wouldn't say a person is '无效.' If you want to say someone is not good at something or is unable to do something, you'd use different vocabulary, like '没能力' (méi nénglì - incapable) or '没用' (méiyòng - useless, but usually for skills or efforts rather than a person's inherent state).
You can use '无效' as an adjective. For example:
这个方法无效。
(Zhège fāngfǎ wúxiào.)
This method is ineffective.
你的票已经无效了。
(Nǐ de piào yǐjīng wúxiào le.)
Your ticket is already invalid.
'无效' is a neutral term, suitable for both formal and informal contexts. It's precise in its meaning of 'ineffective' or 'invalid,' so you'll hear it in everyday conversations as well as in official documents.
Good question! Here are a couple of common ones:
无效合同 (wúxiào hétong): invalid contract
无效票 (wúxiào piào): invalid ticket
努力无效 (nǔlì wúxiào): efforts are ineffective / to no avail
申报无效 (shēnbào wúxiào): declaration is invalid
Not directly as a verb. While it describes a state of being ineffective or invalid, you wouldn't say something '无效s' something. If you want to express 'to invalidate' or 'to render ineffective,' you'd use a verb like '使...无效' (shǐ... wúxiào - to make... ineffective/invalid) or '取消' (qǔxiāo - to cancel).
The most common opposite of '无效' is '有效' (yǒuxiào), which means 'effective' or 'valid.' It follows the same pattern: '有' (yǒu) means 'to have' and '无' (wú) means 'without' or 'lack of.'
Sure! Here's one:
因为天气恶劣，所以今天的航班全部无效了。
(Yīnwèi tiānqì èliè, suǒyǐ jīntiān de hángbān quánbù wúxiào le.)
Because of the bad weather, all flights today are canceled/invalidated.
It can imply a negative outcome, as something being ineffective or invalid is usually not desired. However, the word itself is descriptive rather than inherently negative or accusatory. It simply states a fact about something's functionality or legal standing.
Absolutely. When you're talking about something not fulfilling its intended purpose or not being legally binding, '无效' is the correct choice. For instance, a contract that isn't signed correctly is '无效合同' (wúxiào hétong), not '没用合同' (méiyòng hétong). '没用' is more for general uselessness, like '这个旧手机没用' (zhège jiù shǒujī méiyòng - this old phone is useless).
