When something is 无用 (wú yòng), it means it's useless or serves no purpose. Imagine a broken toy that can't be played with anymore – it's 无用. Or maybe you have a tool that doesn't work for the job you need to do, it's also 无用.
You can use 无用 to describe objects, ideas, or even efforts that don't achieve anything. It's a straightforward way to say something isn't helpful or effective.
When we say something is 无用 (wú yòng), we mean it's useless or serves no purpose. This adjective is straightforward and frequently used in everyday conversation.
For example, if a tool breaks and can no longer be used, you can describe it as 无用. Similarly, if advice or information doesn't help solve a problem, you might say it's 无用.
It's a practical word to know as it directly communicates the lack of utility or effectiveness of something.

- Not useful
- No purpose
- Ineffective
Okay, let's talk about the word 无用 (wú yòng). It's a straightforward adjective in Chinese that means 'useless'. You'll hear it and see it pretty often, so it's a good one to get comfortable with.
- DEFINITION
- Useless; of no use.
§ Basic Sentence Structure with 无用
Like many Chinese adjectives, 无用 can be used directly after a noun to describe it, or it can follow verbs like 'is' (是 shì) or 'feel' (觉得 juéde).
这个东西很无用。
Zhège dōngxi hěn wúyòng.
This thing is very useless.
我觉得这个建议是无用的。
Wǒ juéde zhège jiànyì shì wúyòng de.
I feel this suggestion is useless.
§ Using 无用 with 'De' (的)
When 无用 modifies a noun, especially if it's acting more like an attributive adjective, you'll often see the particle 的 (de) after it. This is standard for adjectives modifying nouns in Chinese.
这是个无用的工具。
Zhè shì ge wúyòng de gōngjù.
This is a useless tool.
无用的争论只会浪费时间。
Wúyòng de zhēnglùn zhī huì làngfèi shíjiān.
Useless arguments only waste time.
§ Common Phrases and Patterns
You'll often see 无用 in a few common patterns. Let's look at some.
- 对...无用 (duì...wúyòng): Useless to/for...
This structure is super common when you want to specify *what* something is useless for or to. Think of 对 (duì) here as 'to' or 'for' in this context.
这个方法对你可能无用。
Zhège fāngfǎ duì nǐ kěnéng wúyòng.
This method might be useless for you.
- 毫无用处 (háowú yòngchù): Completely useless
This is a stronger way to say 'useless'. 毫无 (háowú) means 'not in the least bit' or 'completely without'. 用处 (yòngchù) means 'use' or 'application'. So, literally, it's 'completely without use'.
你说的那些话毫无用处。
Nǐ shuō de nàxiē huà háowú yòngchù.
Those words you said are completely useless.
§ Don't Overthink It
The key is to use it naturally. Don't get stuck trying to find a perfect English equivalent for every particle. Focus on getting the core meaning across. For a word like 无用, it's usually quite direct.
Practice making simple sentences. What objects around you are 无用? What advice have you heard that was 无用? The more you use it, the more natural it will feel.
§ Don't Confuse it with 'No Use' in English
Many English speakers learning Chinese try to directly translate phrases. While '无用' means 'useless', it doesn't always map perfectly to every instance where you might say 'no use' in English. For example, if you want to say 'it's no use crying over spilled milk,' you wouldn't directly translate that with '无用'. Instead, you'd use a more idiomatic expression like '后悔也来不及了' (hòuhuǐ yě láibují le), meaning 'it's too late to regret it'.
§ Using it for People
While you can describe a person as 'useless' in English, using '无用' to describe a person in Chinese can be quite harsh and insulting. It generally implies someone is completely incapable or contributes nothing. If you want to say someone is not good at something, or not performing well, there are softer and more appropriate phrases.
- Bad example
- 他很无用。(Tā hěn wúyòng.) - He is very useless.
This sounds quite strong. Instead, you might say:
他不太擅长这个。(Tā bù tài shàncháng zhège.) - He's not very good at this.
他没什么用。(Tā méi shénme yòng.) - He's not much use. (Still a bit direct, but better than '很无用'.)
§ Incorrect Placement in Sentences
'无用' is an adjective, so it functions like other adjectives. It can come before a noun (e.g., '无用的东西' - useless thing) or after a verb like '是' (shì) or '变得' (biànde).
- Correct usage
- 这个工具很无用。(Zhège gōngjù hěn wúyòng.) - This tool is very useless.
这些建议对他来说是无用的。(Zhèxiē jiànyì duì tā lái shuō shì wúyòng de.) - These suggestions are useless to him.
- Incorrect usage
- 他无用这个工具。(Tā wúyòng zhège gōngjù.) - He useless this tool. (Grammatically incorrect.)
You need to use a verb like '使用' (shǐyòng - to use) or '觉得' (juéde - to feel/think) with '无用'.
他觉得这个工具很无用。(Tā juéde zhège gōngjù hěn wúyòng.) - He thinks this tool is very useless.
§ Overusing it
Like in English, constantly repeating 'useless' can sound repetitive. Chinese has other ways to express similar ideas, such as '没用' (méiyòng - no use, ineffective) which is often more colloquial and slightly less formal than '无用'.
这个方法没用。(Zhège fāngfǎ méiyòng.) - This method is useless/doesn't work.
§ 无用 (wú yòng): The general term
无用 is your go-to word for "useless." It's direct, versatile, and applies to a wide range of situations. Think of it as the default option when something simply has no purpose or value.
这个计划是无用的。
Translation hint: This plan is useless.
这些旧电池已经无用了。
Translation hint: These old batteries are already useless.
§ 没用 (méi yòng): More colloquial and slightly more personal
没用 is very similar to 无用, but it often carries a slightly more colloquial and sometimes more personal tone. You'll hear it more in everyday conversations. While 无用 is simply stating a fact, 没用 can sometimes imply a bit more frustration or disappointment, especially when referring to efforts or advice.
- DEFINITION
- useless; no use
我说了这么多，真是没用。
Translation hint: I said so much, it was really useless.
这个工具太旧了，已经没用了。
Translation hint: This tool is too old, it's already useless.
§ 废物 (fèi wù): A useless thing or person (often derogatory)
废物 is a noun. It refers to a "waste product" or, more strongly, a "good-for-nothing" person. Be careful with this one. When applied to people, it's quite harsh and derogatory. Use it for inanimate objects or as a strong insult.
- DEFINITION
- waste material; good-for-nothing; worthless person
这些旧电器都是废物。
Translation hint: These old appliances are all waste products.
他真是个废物，什么都做不好。
Translation hint: He's really a good-for-nothing, can't do anything right.
§ 冗余 (rǒng yú): Superfluous, redundant, excessive
冗余 is a more formal and technical term, often used in contexts like technology, writing, or systems. It means something is extra, unnecessary, and could be removed without losing essential function. It implies more about efficiency and streamlining rather than just general uselessness.
- DEFINITION
- redundant; superfluous; wordy
这段代码包含很多冗余信息。
Translation hint: This code contains a lot of redundant information.
会议上有很多冗余的讨论。
Translation hint: There were a lot of superfluous discussions at the meeting.
§ When to use which: A quick summary
无用 (wú yòng): General, neutral, covers most situations where something is useless.
没用 (méi yòng): More colloquial, everyday, can imply slight frustration, similar to 无用.
废物 (fèi wù): Noun. For waste materials or, as a harsh insult, a good-for-nothing person. Be careful!
冗余 (rǒng yú): Formal, technical. Used for things that are redundant, superfluous, or excessive, implying they could be streamlined or removed for efficiency.
Start with 无用. If you're talking casually, 没用 works great. Save 废物 for actual waste or when you really want to insult someone (maybe don't do that). Use 冗余 for technical or formal contexts where you mean "redundant."
How Formal Is It?
"我们需要删除那些冗余的信息。(We need to delete that redundant information.)"
"这个旧手机已经没有用了。(This old phone is already useless.)"
"说再多也是白搭，他根本听不进去。(Talking more is useless, he won't listen at all.)"
"这个坏掉的玩具没用处了。(This broken toy is of no use anymore.)"
"你这人真是废了，什么都做不好。(You're really useless, can't do anything right.)"
재미있는 사실
The character 无 (wú) means 'none' or 'without', and 用 (yòng) means 'to use' or 'use'. So, '无用' literally means 'without use'.
발음 가이드
- Don't pronounce the 'u' in 'wu' like the 'u' in 'put'. It's more like the 'oo' in 'moon'.

Sample answer
我认为在当前的数字时代，传统的手写信件能力变得越来越无用。虽然它具有一定的艺术性和个人魅力，但在日常工作交流中，电子邮件和即时通讯工具已经完全取代了它的地位，效率更高，也更符合现代社会的需求。花时间练习复杂的笔迹和信函格式，对于提升职业竞争力而言，其投入产出比已经非常低。
假设你正在进行一场关于环境保护的辩论，你的论点是某些现有的环保措施是“无用”的。请阐述你的观点并提供至少两个理由。
Well written! Good try! Check the sample answer below.
Sample answer
在环境保护的辩论中，我认为一些现有的环保措施确实显得无用。首先，许多地方推广的分类垃圾桶，在实际操作中并没有得到严格执行，各种垃圾最终仍被混合处理，这使得最初的分类努力形同虚设，浪费了资源和人力。其次，部分旨在限制某种特定污染物的法规，由于技术更新或替代方案的出现，已经变得过时甚至阻碍了更有效的新技术发展，反而成为了进步的绊脚石。这些“无用”的措施不仅没有解决问题，反而可能造成了新的资源浪费和效率低下。

This sentence means 'Ultimately, these findings of his are useless.' The structure is 'Subject (他 的 这些 发现) + 是 (is) + Adjective (无用 的)'. '最终' (ultimately) acts as an adverb modifying the entire statement.
