没有 vs 无 (méiyǒu vs wú): absence and lack in spoken vs literary Chinese
Both 没有 and 无 express absence or lack, but they differ drastically in register and syntax. 没有 is the everyday spoken word for 'not have' or 'there is not', used freely as a verb or adverb. 无 is a classical/literary word that appears mainly in fixed compounds (无关, 无效) and formal writing; it cannot stand alone as a verb. Use 没有 for general negation of possession or existence, and 无 only in set phrases or formal contexts.
没有 (méiyǒu) and 无 (wú) both convey that something is absent, lacking, or not present. However, they operate in different registers and syntactic environments. 没有 is a free morpheme that functions as both a verb (negating 有 'have') and an adverb (negating past actions or states). It is the standard choice in everyday speech and writing. 无 is a bound morpheme derived from Classical Chinese; it never appears alone as a verb and is always part of fixed expressions (e.g., 无关 'unrelated', 无效 'invalid') or formal compounds (e.g., 无线 'wireless'). Choosing 无 in place of 没有 in a simple statement like 'I have no money' would sound archaic or unnatural.
When to use each
Use 没有 in general spoken and written language to express: (1) lack of possession – 我没有钱 (I have no money); (2) existential negation – 没有人在家 (There is no one at home); (3) negation of past actions – 我没去 (I did not go). It is the default, free-standing form and can be negated by 没 alone in informal speech (e.g., 没钱).
In colloquial Chinese, 没 alone can replace 没有 before verbs (e.g., 我没吃饭), but 没有 is always used for possession (没有钱) and existential negation (没有人).
Use 无 in formal, literary, or fixed expressions. It always appears attached to a noun or in compound words: e.g., 无关 (irrelevant), 无效 (invalid), 无家可归 (homeless). 无 is also common in idioms and classical quotations. It cannot function as a standalone verb; saying *我无钱 is grammatically incorrect in modern Chinese.
Some set phrases with 无 are even used in everyday language, like 无聊 (bored, boring) and 无赖 (rascal). In these cases, 无 is inseparable from the word – you cannot replace it with 没有.

Examples
- 没有我没有钱买这本书。Wǒ méi yǒu qián mǎi zhè běn shū.I don't have money to buy this book.Possession negation – 无 would be incorrect here.
- 无这件事与我无关。Zhè jiàn shì yǔ wǒ wú guān.This matter has nothing to do with me.Fixed expression 无关 (unrelated); 没有 cannot replace 无.
- 没有没有人知道答案。Méi yǒu rén zhī dào dá àn.No one knows the answer.Existential negation – standard in speech and writing.
- 无这个产品无效。Zhè ge chǎn pǐn wú xiào.This product is invalid / not effective.Compound 无效 (invalid); formal usage.
- 没有昨天我没有去公司。Zuó tiān wǒ méi yǒu qù gōng sī.Yesterday I did not go to the company.Past action negation – 无 cannot be used here.
- 无他成了无家可归的人。Tā chéng le wú jiā kě guī de rén.He became a homeless person.Set phrase 无家可归 (homeless); literary origin, still used.
Common mistakes
- Using 无 instead of 没有 in possession statements: e.g., *我无钱 is archaic/wrong – use 我没有钱.
- Using 没有 to replace 无 in fixed compounds: e.g., *没有关 instead of 无关 (unrelated) – 没有 cannot attach to nouns like that.
- Overusing 无 in casual speech where it sounds overly formal: e.g., *我无时间 (I have no time) – use 我没有时间.
- Confusing 没有 with 没 in front of verbs: 没 alone is fine (我没看), but 无 cannot be used for verb negation at all.
FAQ
- When do I use 没有 vs 无?
- Use 没有 for everyday negation of possession (没有钱), existence (没有人), and past actions (没有去). Use 无 only in fixed expressions (无关, 无效) or formal writing; do not use 无 as a standalone verb in modern Chinese.
- Can 无 ever be replaced by 没有 in fixed phrases like 无聊?
- No. 无聊 (bored/boring) is a fixed compound; replacing 无 with 没有 would produce nonsense (*没有聊). Similarly for 无赖, 无礼, etc.
- Is 无 used in spoken Chinese at all?
- Only in a few common set expressions (e.g., 无所谓 'doesn't matter', 无论如何 'regardless'), but even these are somewhat formal. For everyday speech, stick with 没有.
- What about 没 vs 没有? Is that the same as the 没有 vs 无 distinction?
- No. 没 is just a short form of 没有 used before verbs (e.g., 没钱 = 没有钱, 没看 = 没有看). 无 is a completely different word not interchangeable with 没.
