不 vs 没 vs 无: Negating possession and existence
When negating the verb 有 (to have) or expressing absence of possession or existence, use 没 (méi) or 没有 — never 不 (bù). 无 (wú) is a formal/literary synonym of 没(有), used in fixed expressions, idioms, and formal writing. This page explains when to choose each term.
The choice between 不, 没, and 无 depends on whether you're negating possession/existence, the register of speech, and the grammatical context. 不 cannot directly negate 有; instead, 没 (or 没有) is the standard negation for 'have' and for indicating that something does not exist or is not present. 无 is a more formal, literary alternative that can replace 没有 in certain fixed phrases and written registers, but it does not function as a standalone verb in spoken Mandarin.
When to use each
不 is used to negate verbs other than 有, adjectives, and modal verbs. It expresses negation of actions, states, habits, or volition (e.g., 不去, 不好, 不喜欢). It is never used directly before 有 in modern Mandarin to negate possession or existence.
In classical Chinese or a few fixed expressions, 不 can appear before 有 (e.g., 不有命乎), but these are rare and not productive in everyday modern Mandarin.
没 (or the longer form 没有) is the standard negation for 有 when indicating lack of possession, existence, or occurrence. It can function alone as a verb meaning 'not have' (e.g., 我没钱, 屋里没人). It is also used to negate completed actions (e.g., 没去).
没 can replace 没有 in most contexts; 没 is slightly more informal but completely standard and natural. In negative answers to 有 questions, 没 alone is correct (e.g., 有吗?— 没).
无 is a formal/literary word meaning 'without' or 'not have'. It is used in set phrases, idioms (e.g., 无能为力, 无人不知), formal writing, and when a classical tone is desired. It is not used as a standalone verb in spoken conversation; instead, 没(有) is preferred.

Examples
- 不我不喜欢咖啡。Wǒ bù xǐhuān kāfēi.I don't like coffee.不 negates the verb 喜欢, not possession.
- 没我没有钱。Wǒ méiyǒu qián.I don't have money.没(有) correctly negates possession.
- 没屋里没人。Wū lǐ méi rén.There is no one in the room.没 alone means 'not have' (existence).
- 无无家可归。Wú jiā kě guī.Homeless (without home to return to).无 in a fixed idiom; cannot be replaced by 没 here.
- 不✗我不有钱。Wǒ bù yǒu qián.I don't have money. (incorrect)✗ Wrong: 不 cannot negate 有; use 没有钱.
- 无这个问题无意义。Zhège wèntí wú yìyì.This question is meaningless.无 used in a formal expression; 没有意义 is also possible but less formal.
Common mistakes
- Using 不 with 有 to negate possession: '不有' is not standard modern Chinese; use 没(有).
- Using 没 to negate habitual actions (e.g., '我每天没去' for 'I don't go every day') — should use 不: 我每天不去.
- Using 无 as a standalone verb in spoken Chinese (e.g., '我无钱' instead of '我没有钱') — sounds unnatural and overly literary.
- Confusing 没 with 不 when negating adjectives (e.g., '没好' for 'not good') — use 不好.
FAQ
- When do I use 没 vs 不 to negate possession?
- Always use 没 (or 没有) to negate 有 or to say 'not have'. 不 is never correct with 有 in modern Mandarin.
- Can I use 无 like 没有 in everyday conversation?
- Not usually. 无 is considered literary and appears in idioms, written Chinese, or formal speech. In daily conversation, stick with 没(有).
- Is '没有' always interchangeable with '没'?
- Yes, in most contexts they are, but 没 is slightly more informal and is preferred in short negatives (e.g., 有没有? — 没). 没有 is also fine.
