什么 vs 任何 (shénme vs rènhé): which “any” to use
什么 (shénme) is an interrogative pronoun that also serves as an indefinite 'any' in negative or question contexts, often with 都/也. 任何 (rènhé) is a formal determiner meaning 'any (kind of)' and can be used in affirmative, negative, and question sentences. The main distinction is formality and syntactic range: 任何 is more specific and formal, while 什么 is colloquial and typically restricted to negative or emphatic frames.
Both 什么 and 任何 can express the idea of 'any' in Chinese, but they belong to different parts of speech and have distinct usage patterns. 什么 is primarily an interrogative pronoun ('what') and only takes an indefinite 'any' meaning in negative sentences (e.g., 什么都不… 'not… anything') or in rhetorical questions. 任何 is a determiner that explicitly means 'any (kind, amount, etc.)' and can appear in affirmative, negative, and question sentences, often paired with 都 or 也 for emphasis. Choosing between them depends on formality, sentence polarity, and whether you need a noun modifier (任何 must be followed by a noun) or a standalone pronoun (什么 can stand alone).
When to use each
Use 什么 as 'any' primarily in negative sentences (with 不/没 + 都/也) or in questions where 'any' is implied. It is colloquial and often replaces a specific noun when the exact thing is unknown or irrelevant. For example, 我什么都没看见 (I didn't see anything). 什么 can also be used in affirmative statements with 都/也 to mean 'everything' (什么都知道 'know everything'), but this is not the same as 'any'.
In negative sentences, 什么 is very common and sounds natural; in affirmative 'any' contexts (e.g., 'any person can do this'), 什么 is ungrammatical unless used in a rhetorical question. Do not use 什么 as 'any' in formal writing or in affirmative statements without 都/也.
Use 任何 when you want to specify 'any (kind of)' in a formal or neutral context, especially before a noun. It works in affirmative, negative, and question sentences, and is often followed by 都 or 也 to emphasize 'no matter which'. For example, 任何问题都可以问 (Any question can be asked). 任何 is required when 'any' modifies a noun in a positive statement without a following verb (e.g., 任何选择都行 'Any choice is fine').
任何 is more formal than 什么 and cannot stand alone as a pronoun; it must be followed by a noun or a measure word noun phrase. In colloquial speech, 什么 is often preferred for negatives, while 任何 sounds more precise or emphatic.

Examples
- 什么我什么都没看见。Wǒ shénme dōu méi kànjiàn.I didn't see anything.什么 in a negative sentence with 都, meaning 'any thing' = 'nothing'.
- 任何他没有吃任何东西。Tā méiyǒu chī rènhé dōngxi.He didn't eat anything.任何 modifies 东西 (thing) in a negative sentence; more formal than 什么都没吃.
- 任何任何时间都可以。Rènhé shíjiān dōu kěyǐ.Any time is fine.Affirmative use: 任何 + noun + 都 + adjective/verb.
- 什么你什么都不懂！Nǐ shénme dōu bù dǒng!You don't understand anything!什么 with 都+不 in a negative-emphatic sentence.
- 什么没有什么是不可能的。Méiyǒu shénme shì bù kěnéng de.Nothing is impossible.什么 as indefinite pronoun in negative existential sentence; correct contrast with 任何.
- 任何没有任何事情是不可能的。Méiyǒu rènhé shìqing shì bù kěnéng de.Nothing is impossible.任何 + 事情 (thing) in negative existential; more formal than the 什么 version.
Common mistakes
- Using 什么 as 'any' in an affirmative statement without 都/也, e.g., '什么人可以来' to mean 'Any person can come'. Correct: 任何人都可以来 or 什么人都可以来 (with 都).
- Using 任何 as a standalone pronoun, e.g., '任何都可以' to mean 'anything is fine'. Correct: 任何东西都可以 or 什么都可以.
- Using 什么 in formal writing where 任何 is more appropriate, e.g., '如果有什么问题' is okay, but in a legal document, '如有什么问题' should be '如有任何问题'.
- Omitting 都/也 after 什么 in negative sentences for 'any' meaning, e.g., '我什么没吃' instead of '我什么都没吃'.
FAQ
- When do I use 什么 vs 任何 for 'any'?
- Use 什么 in informal, negative sentences (with 都/也) to mean 'anything' or 'nothing'. Use 任何 in more formal contexts or in affirmative sentences before a noun to specify 'any kind of'. For negative sentences, both are possible: 什么都没说 and 没有任何话说 are both correct, but the first is casual, the second more formal.
- Can I use 任何 in a sentence like 'Any person can learn'?
- Yes, in affirmative: 任何 (的) 人都能学习。 You can also use 什么 with 都: 什么人都能学习。 Both are correct, but 任何 sounds more precise and formal; 什么 with 都 is more spoken.
- Is there a difference in negation between 什么 and 任何?
- Both can appear in negative sentences, but 什么 is more common in daily speech. 任何 in negatives emphasizes 'not a single (thing/person)', e.g., 没有任何痕迹 'there is no trace at all'. 什么 in negatives is more generic, e.g., 没什么 'it's nothing'.
- Can 什么 mean 'any' in affirmative sentences without 都/也?
- No, not as 'any'. In an affirmative sentence without 都/也, 什么 keeps its interrogative meaning ('what') or can mean 'something' in a casual tone (e.g., 我想吃什么 'I want to eat something'). To express 'any' in an affirmative, use 任何 + noun (+ 都) or 什么 + noun + 都.
