Explanation 无误 in your Level:

At the A1 level, you are just starting to learn basic words for 'yes' and 'no.' While '无误' (wú wù) might seem a bit advanced, you can think of it as a very strong and formal way to say 'correct.' It is made of two parts: '无' (no/none) and '误' (mistake). So, it literally means 'no mistake.' You will mostly see this word on buttons in apps or on forms. For example, if you see a button that says '确认无误,' it just means 'Confirm it is correct.' You don't need to use it in your own speaking yet, but recognizing it will help you navigate Chinese websites and apps. Just remember: it's like a formal 'check mark' for information like your name, phone number, or the price of something you are buying.

At the A2 level, you should begin to recognize '无误' (wú wù) as a formal adjective. It is commonly used when you are checking information. Unlike the word '对' (duì), which you use with friends, '无误' is used in shops, banks, and offices. A common phrase is '核对无误' (héduì wúwù), which means 'checked and found to be correct.' You can use it in simple sentences like '信息无误' (The information is correct). It shows that you are being careful and professional. If you are filling out a form in a Chinese class or at a registration desk, and the clerk asks you to check your name, you can say '无误' to sound more like a native speaker who is paying attention to detail.

For B1 learners, '无误' (wú wù) becomes a useful tool for business and official communication. You should understand that it functions as a predicative adjective, meaning it usually comes after the noun it describes (e.g., '数据无误'). You should also start using the four-character phrase '准确无误' (zhǔnquè wúwù) to describe things that are both accurate and free of errors. This is very common in work reports or when giving instructions. For example, '请确保报告中的数据准确无误' (Please ensure the data in the report is accurate and without error). At this level, you should also be able to distinguish '无误' from '正确'—the former implies a verification process, while the latter is more general.

At the B2 level, you should be comfortable using '无误' (wú wù) in a variety of formal contexts, including legal, financial, and technical discussions. You should understand the nuance that '无误' is an absolute state; something is either error-free or it isn't. Therefore, you wouldn't typically use degree adverbs like '很' (very) with it, but you might use '完全' (completely) or '确实' (indeed). You should also be familiar with its antonym '有误' (yǒu wù) and use them together in proofreading contexts. For instance, '如果发现有误，请及时更正；若核对无误，请签字确认' (If errors are found, please correct them promptly; if confirmed without error, please sign). This level of precision is expected in professional B2-level communication.

At the C1 level, you should appreciate the stylistic value of '无误' (wú wù) in formal writing and literature. It is often used to create a tone of authority and meticulousness. You should be able to identify its use in classical-leaning modern Chinese (Shūmiànyǔ), where '无' and '有' are preferred over '没有' and '有.' You might encounter it in academic papers where '实验结果无误' (experimental results are without error) serves as a foundational claim for further argument. Furthermore, you should be able to use it in complex sentence structures, such as '在确保万无一失的前提下，力求做到数据的准确无误' (On the premise of ensuring nothing goes wrong, strive for the accuracy and error-free nature of the data). Your usage should reflect an understanding of its formal register.

For C2 learners, '无误' (wú wù) is a standard part of your high-level vocabulary, used with precision and stylistic flair. You should be able to use it in legal drafting, high-level diplomatic communication, or complex technical specifications. You understand its historical roots and how the character '误' can also imply 'delay' or 'neglect' in certain classical contexts, though in '无误' it strictly means 'error.' You can use it to construct sophisticated rhetorical structures, perhaps contrasting the 'apparent' correctness with the 'verified' (无误) reality. Your mastery involves knowing exactly when '无误' provides the necessary weight to a statement that '正确' or '对' simply cannot provide, ensuring your professional persona in Chinese is impeccable.

无误 in 30 Seconds

无误 (wú wù) is a formal Chinese adjective meaning 'without error' or 'correct,' often used for verified data.
It is commonly found in phrases like '确认无误' (confirmed correct) in banks, apps, and official forms.
Unlike the casual '对' (right), '无误' implies a process of checking or auditing information for accuracy.
It is a key term for professional Chinese, ensuring that names, numbers, and facts are perfectly accurate.

The Chinese term 无误 (wú wù) is an adjective that translates directly to 'without error' or 'correct.' In the landscape of the Chinese language, it occupies a space of formal verification and absolute certainty. It is composed of two characters: 无 (wú), which is a negation meaning 'none' or 'without,' and 误 (wù), which means 'error,' 'mistake,' or 'misunderstanding.' When these two are combined, they describe a state where something has been scrutinized and found to be perfectly accurate. While the word '正确' (zhèngquè) simply means 'correct,' 无误 carries a stronger nuance of having been checked or verified against a standard. It is the language of auditors, bank tellers, software developers, and meticulous planners. You won't typically hear a child say their math homework is '无误' in a casual conversation; instead, you'll hear it in professional environments where the cost of a mistake is high.

Morphology: The character 无 (wú) is the simplified version of 無, representing the absence of something. 误 (wù) contains the speech radical 讠, suggesting that many errors originate in communication or misinterpretation.

In modern usage, 无误 is most frequently seen in the phrase '确认无误' (quèrèn wúwù), which means 'to confirm that there are no errors.' This is a standard button label in banking apps, a standard line in legal contracts, and a common verbal confirmation in logistics. It implies a process of comparison. For example, if you are checking a list of names against a set of ID cards, once the match is perfect, you declare the results '无误.' It is a binary state: either there is an error, or there is 无误. This makes it a very powerful word in technical writing and formal speech because it leaves no room for ambiguity. It is not about being 'mostly right'; it is about being 'entirely without fault.'

经核对，这本账目记录无误。(Jīng héduì, zhè běn zhàngmù jìlù wúwù.) - After checking, these account records are without error.

Register: Formal and Written. It is rarely used in casual slang but is essential for business Chinese and official documentation.

Furthermore, the word is often used in the context of time and schedules. If a train arrives exactly when it is supposed to, or if a sequence of events follows a plan perfectly, one might say the execution was '准确无误' (zhǔnquè wúwù). This four-character idiom (chengyu-like structure) combines 'accurate' with 'without error' to emphasize extreme precision. For a learner at the A2 level, understanding this word helps transition from basic 'yes/no' or 'right/wrong' vocabulary into the more nuanced world of professional Chinese. It signals to the listener that you are paying attention to detail and that you value accuracy.

请确保您的地址填写无误。(Qǐng quèbǎo nín de dìzhǐ tiánxiě wúwù.) - Please ensure your address is filled out without error.

In summary, 无误 is your 'stamp of approval.' It is the word used when the checking is done and the result is perfect. Whether you are dealing with numbers, names, or logic, 无误 is the gold standard for correctness in the Chinese administrative and professional world. By mastering its use, you demonstrate a higher level of linguistic sophistication and a commitment to precision that is highly valued in Chinese culture.

Cultural Context: In Chinese society, 'mianzi' (face) is often tied to accuracy in work. Using '无误' provides a formal assurance that protects the reputation of the person providing the information.

实验结果经过多次验证，准确无误。(Shíyàn jiéguǒ jīngguò duōcì yànzhèng, zhǔnquè wúwù.) - The experimental results have been verified many times and are accurate and without error.

这份合同的内容无误，可以签字了。(Zhè fèn hétóng de nèiróng wúwù, kěyǐ qiānzì le.) - The content of this contract is without error; it can be signed.

Using 无误 (wú wù) correctly requires understanding its role as a predicative adjective. Unlike '正确' (zhèngquè), which can easily function as an attributive adjective (e.g., '一个正确的答案' - a correct answer), 无误 is most commonly found at the end of a clause or sentence to describe a state of being. It often follows a noun that represents information, data, or a document. For example, you would say '信息无误' (The information is correct) rather than '无误的信息' (though the latter is grammatically possible in some specific technical contexts, it sounds unnatural in daily speech). This structure emphasizes the conclusion reached after a verification process.

Common Subject Types: Common subjects for 无误 include: 数据 (shùjù - data), 账目 (zhàngmù - accounts), 事实 (shìshí - facts), 地址 (dìzhǐ - address), 姓名 (xìngmíng - name), and 结果 (jiéguǒ - results).

One of the most frequent patterns is '[Noun] + 确认 + 无误.' This means '[Noun] has been confirmed to be without error.' For instance, '身份证号码确认无误' (The ID card number is confirmed to be correct). This pattern is ubiquitous in digital interfaces. When you use an ATM in China, after entering the amount, the screen might ask you to '确认金额无误' (confirm the amount is correct). Here, 无误 acts as the complement to the confirmation action. It specifies the condition that must be met before the user proceeds to the next step.

请在签字前核对个人信息无误。(Qǐng zài qiānzì qián héduì gèrén xìnxī wúwù.) - Please check that your personal information is without error before signing.

Another important usage is in the four-character phrase '万无一失' (wàn wú yī shī), which is related in spirit. While not using the word '无误' directly, it shares the '无' (none) prefix and implies a state where no mistake can possibly happen. However, focusing back on 无误, it can also be modified by adverbs of degree like '完全' (wánquán - completely) or '确实' (quèshí - indeed), though it is less common to see it modified by '很' (hěn - very) because 'without error' is usually seen as an absolute state. You are either without error, or you have an error.

Sentence Pattern 1: [Subject] + [Verb: 核对/检查/确认] + 无误. (Subject is checked/confirmed to be without error.)

In professional writing, you will see 无误 used to provide assurance. A report might conclude with '以上数据经审计无误' (The above data has been audited and found to be without error). This usage is very common in financial and legal documents. It provides a formal 'all clear.' If you are writing an email to a colleague in Chinese, using 无误 instead of '对' (duì) makes you sound more professional and thorough. It shows that you haven't just glanced at the work, but you have verified it.

经过仔细检查，我们发现系统运行无误。(Jīngguò zǐxì jiǎnchá, wǒmen fāxiàn xìtǒng yùnxíng wúwù.) - After careful inspection, we found the system is running without error.

Sentence Pattern 2: 确保 (Quèbǎo) + [Object] + 无误. (Ensure [Object] is without error.)

Finally, consider the negative potential. While 无误 itself means 'no error,' if you want to say something *does* have an error, you would use '有误' (yǒu wù). This creates a neat symmetrical pair: 无误 (no error) vs. 有误 (has error). This pair is used constantly in proofreading and data validation. '如果发现有误，请及时联系我们' (If you find errors, please contact us promptly). By learning 无误, you automatically gain the ability to use its counterpart, 有误, effectively doubling your utility in professional Chinese communication.

报告中的每一项事实都必须做到准确无误。(Bàogào zhōng de měi yī xiàng shìshí dōu bìxū zuò dào zhǔnquè wúwù.) - Every fact in the report must be accurate and without error.

你的回答完全无误，非常棒！(Nǐ de huídá wánquán wúwù, fēicháng bàng!) - Your answer is completely without error, excellent!

If you are living in or visiting a Chinese-speaking environment, you will encounter 无误 (wú wù) in several specific, high-stakes contexts. One of the most common places is the bank. Whether you are filling out a deposit slip or setting up a mobile banking app, the staff or the interface will repeatedly ask you to '确认信息无误' (confirm the information is correct). In this setting, the word acts as a legal safeguard. By confirming that the data is '无误,' you are taking responsibility for its accuracy. You might hear a bank teller say: '请核对一下金额，如果没有问题，请在确认无误处签字' (Please check the amount; if there are no problems, please sign where it says 'confirmed without error').

Context: Logistics & Deliveries: When receiving a package from a courier (kuàidì), you might be asked to check the contents. If everything is there, the courier might say, '请确认货物无误后签收' (Please sign after confirming the goods are correct).

Another frequent environment for this word is the airport or train station. When you present your passport or ID card, the official is performing a '核对' (héduì - verification). If your document matches their records, they might internally note that the '身份信息无误' (identity information is without error). If you are listening to announcements or reading instructions on automated kiosks, '无误' will appear as the standard term for 'validated' or 'correct.' It is a word that provides a sense of security and finality in these bureaucratic processes.

请检查您的登机牌信息是否无误。(Qǐng jiǎnchá nín de dēngjīpái xìnxī shìfǒu wúwù.) - Please check if your boarding pass information is without error.

In the workplace, particularly in fields like accounting, engineering, or IT, 无误 is part of the daily jargon. During a code review, a programmer might say, '这段代码逻辑无误' (The logic of this code segment is without error). In a meeting, a manager might ask, '数据核对过了吗？是否无误？' (Has the data been checked? Is it without error?). It is a word used to communicate reliability. If you describe your work as '无误,' you are making a strong claim about its quality. It is also used in academic settings, especially in mathematics and science, to describe the correctness of a proof or a calculation result.

Context: Healthcare: Nurses and doctors use '无误' when verifying patient names and medication dosages to prevent medical errors. '患者姓名确认无误' (Patient name confirmed without error).

You will also see it on official websites and apps. When you are registering for a service, after you enter your phone number and the verification code, the system might display a message like '验证无误' (Verification successful/without error). This digital context is perhaps where younger speakers encounter the word most frequently today. It has become the standard UI (User Interface) term for successful validation. Even in casual shopping, if you are buying something expensive, the salesperson will likely say, '请您再次核对一下商品，确认无误后我们为您包装' (Please check the item again; once confirmed without error, we will pack it for you).

经专家组评审，该方案设计无误。(Jīng zhuānjiāzǔ píngshěn, gāi fāng'àn shèjì wúwù.) - After review by the expert group, the design of the plan is without error.

点击按钮前，请确认所选项目无误。(Diǎnjī ànniǔ qián, qǐng quèrèn suǒxuǎn xiàngmù wúwù.) - Before clicking the button, please confirm that the selected items are without error.

One of the most frequent mistakes English speakers make when using 无误 (wú wù) is treating it as a direct synonym for 'right' or 'correct' in all contexts. In English, we use 'right' for everything: 'You are right,' 'That's the right way,' 'This answer is right.' However, in Chinese, 无误 is much more specific. You should not use it to agree with someone's opinion. If a friend says, 'I think we should go to the park,' and you agree, saying '无误' would sound extremely strange and overly formal, like an auditor approving a financial statement. In that case, you should use '对' (duì) or '没错' (méicuò).

Mistake 1: Casual Agreement: Incorrect: '你说得无误。' (Nǐ shuō de wúwù.) - Sounds like a robot. Correct: '你说得对。' (Nǐ shuō de duì.)

Another common error is using 无误 as a verb. Some learners try to say 'I will 无误 this paper,' meaning 'I will make this paper error-free.' This is incorrect. 无误 is an adjective describing a state. If you want to say 'to correct errors,' you should use '纠正' (jiūzhèng) or '修改' (xiūgǎi). You can use 无误 as the *result* of the action, but not the action itself. For example, '把文章修改到无误为止' (Modify the article until it is without error). Notice how 无误 follows '到...为止' (until), describing the final state.

错误：我要无误我的作业。(Incorrect: I want to 'without error' my homework.)

Confusion with the word '错误' (cuòwù) is also common. '错误' is a noun or adjective meaning 'error' or 'wrong.' Some learners might accidentally say '无错误' (wú cuòwù). While '无错误' is technically understandable, it's redundant because '无误' already means 'no error.' The character '误' in '无误' already carries the meaning of '错误.' Using '无误' is the more natural, native way to express the absence of mistakes in a formal context.

Mistake 2: Degree Modifiers: Avoid saying '很无误' (very without error). Since it's an absolute state, 'very' doesn't make much sense. Use '完全无误' (completely without error) instead.

Lastly, learners sometimes forget the '核对' (héduì) or '确认' (quèrèn) aspect. In English, we might say 'The data is correct.' In Chinese, while you can say '数据无误,' it is much more natural to say '数据确认无误' or '经核对，数据无误.' The word 无误 is almost always the result of an inspection. If you use it without any context of checking, it can sound a bit abrupt. Always try to pair it with the concept of verification to sound like a native speaker.

错误：他是一个无误的人。(Incorrect: He is a 'without error' person. You should use '完美' or '正直'.)

正确：经过核实，你的说法确实无误。(Correct: After verification, your statement is indeed without error.)

To truly master 无误 (wú wù), it is essential to compare it with other Chinese words that mean 'correct,' 'accurate,' or 'right.' The most basic alternative is 正确 (zhèngquè). While both can be translated as 'correct,' 正确 is much broader. It can refer to a correct answer, a correct ideology, or a correct way of doing things. 无误, on the other hand, is specifically about the *absence of errors* in factual information or data. If you are talking about a math problem, both work, but 无误 sounds like you have double-checked the work.

无误 vs. 正确: 正确 (zhèngquè) is 'correct' in a general sense. 无误 (wúwù) is 'error-free,' often implying a verification process.

Another close synonym is 准确 (zhǔnquè), which means 'accurate.' 准确 is often used for measurements, time, or predictions. While '准确无误' is a common combined phrase, they have different focuses. 准确 is about hitting a target or being precise, whereas 无误 is about not making a mistake. For example, a clock can be 准确 (accurate time), and a calculation can be 无误 (no errors). If a sniper hits a target, we say his aim is 准确, not necessarily 无误 (though 无误 could describe his records of the hits).

这台机器的测量非常准确。(Zhè tái jīqì de cèliáng fēicháng zhǔnquè.) - This machine's measurements are very accurate.

无误 vs. 精确: 精确 (jīngquè) means 'precise.' It is used in science and high-level math. 无误 is more about the binary state of 'right or wrong.'

For casual situations, the most common word is simply 对 (duì) or 没错 (méicuò). If you are confirming a dinner time with a friend, use '对.' If you are confirming the amount of money you are transferring to that friend, use '无误.' Using 无误 in casual conversation can make you sound like you're reading from a script. However, if you want to emphasize that there is absolutely no mistake, you might say '完全没错' (wánquán méicuò), which is the informal equivalent of '完全无误.'

Lastly, consider the word 恰当 (qiàdàng), which means 'appropriate' or 'proper.' This is used when something is 'correct' in a social or contextual sense. For example, using the 'correct' (恰当) words at a funeral. 无误 would never be used here because a funeral isn't a data set to be verified. In conclusion, choose 无误 when you want to sound professional, thorough, and focused on factual accuracy. Choose 正确 for general correctness, 准确 for precision, and 对 for everyday agreement.

他的判断非常准确，帮我们避开了风险。(Tā de pànduàn fēicháng zhǔnquè, bāng wǒmen bìkāile fēngxiǎn.) - His judgment was very accurate and helped us avoid risks.

老师说我的解题思路是正确的。(Lǎoshī shuō wǒ de jiětí sīlù shì zhèngquè de.) - The teacher said my way of solving the problem is correct.
