没 vs 没有 (méi vs méiyǒu): Short vs full negator
In Mandarin, 没 (méi) is a shortened form of 没有 (méiyǒu) used before a verb or noun. The key difference is that 没 cannot stand alone or end a clause, while 没有 can be used independently as a negative answer or at the end of a sentence. Learners must choose based on syntactic position and formality.
Both 没 and 没有 negate verbs in the past (indicating an action did not happen) or negate existence (meaning 'not have'). 没 is the informal shortened form that must be directly followed by a verb or noun; it cannot appear alone or at the end of a sentence. 没有 is the full form that can be used as a standalone negative answer, at the end of a clause, or before a verb/noun for added emphasis or in more formal contexts. In speech, 没 alone as an answer is perfectly natural and correct.
When to use each
Use 没 before a verb or noun to negate a past action or indicate lack of existence. It is the most common choice in informal speech when followed by a word. Never use 没 alone as a full sentence in formal writing, though it is acceptable in casual spoken answers.
In very informal spoken Chinese, 没 can stand alone as a one-word negative answer (e.g., 没. 'No.'), but this is less formal than using 没有.
Use 没有 as the full form when you need a standalone negative answer, when 没 would leave an incomplete clause (e.g., at the end of a sentence), or when you want a more formal or emphatic negation. It can also be used before a verb or noun just like 没, but is slightly more explicit.
没有 is the only form that can serve as a complete verb phrase meaning 'not have' when the object is omitted (e.g., 我有，他没有. 'I have it, he doesn't.')

Examples
- 没他没来。Tā méi lái.He didn't come.没 used before the verb 来; 没有 could also be used but is less common in spoken Chinese.
- 没有他没有钱。Tā méiyǒu qián.He doesn't have money.没有 as verb meaning 'not have'; 没 before a noun (没钱) is also correct and more casual.
- 没你吃了吗？没。Nǐ chī le ma? Méi.Did you eat? No.In informal spoken Chinese, 没 alone is a perfectly natural negative answer. Formal answer would use 没有.
- 没有我有时间，他没有。Wǒ yǒu shíjiān, tā méiyǒu.I have time, he doesn't.没有 at the end of the clause – 没 cannot be used here.
Common mistakes
- Using 没 alone as a one-word answer in formal writing (use 没有).
- Using 没 at the end of a clause, e.g., *我钱没* instead of 我没有钱 or 我没钱.
- Confusing 没 with 不; 没 is for past or lack of existence, 不 is for present or habitual negation.
- Writing 没有 as 没 when the verb or noun is omitted but the clause continues, e.g., *他没，我不* (should be 他没有，我没有).
FAQ
- When do I use 没 vs 没有?

- Can 没 stand alone as an answer?
- Yes, in informal spoken Chinese, 没 alone (e.g., 没) is a very common and correct negative answer. In formal writing or when you want to be explicit, use 没有 instead.
- Is there a difference in formality between 没 and 没有?
- Yes. 没 is generally informal and preferred in spoken language. 没有 is neutral and can be used in both formal and informal contexts. When emphasis or clarity is needed, 没有 is often chosen.
- Why can't I use 没 at the end of a sentence?
- 没 is a bound form that clings to the following word; it cannot stand alone or end a clause. For sentence-final negation, you must use 没有 (e.g., 他吃过饭，我没有).
