什么 (shénme) is the first question word most learners meet, and it does more work than English "what." It asks "what" as a standalone object or subject, and — placed directly in front of a noun — it means "what kind of / which." The single most important thing to unlearn from English is word order: Chinese does not move the question word to the front. 什么 sits exactly where the answer will sit, in the same slot in the sentence. Master that "in-situ" habit here and every other question word on this guide becomes easy, because they all obey the same rule.
什么 stands in the answer's slot
English fronts its question words: "What do you want to eat?" moves "what" to the head of the clause. Mandarin does the opposite — it leaves 什么 in the object slot, so the question looks structurally identical to its own answer. Compare 你想吃什么？ ("you want to eat what?") with the reply 我想吃面条 ("I want to eat noodles"): 什么 and 面条 occupy the very same position. This is the core logic — a content question in Chinese is just a statement with a question word dropped into the blank.
这是什么？
zhè shì shénme?
What is this? (neutral) — 什么 sits in the predicate slot, where the answer '书 / 手机' would go.
你想吃什么？
nǐ xiǎng chī shénme?
What do you want to eat? (informal) — 什么 stays in the object position after 吃.
你说什么？
nǐ shuō shénme?
What did you say? (informal) — also the go-to phrase when you didn't catch something.
你叫什么名字？
nǐ jiào shénme míngzi?
What's your name? (neutral) — literally 'you are-called what name', 什么 in situ.
什么 also fills the subject slot when you're asking what causes or is something. It still doesn't move — it just sits at the front because that's where a subject already lives:
什么让你这么开心？
shénme ràng nǐ zhème kāixīn?
What's making you so happy? (informal) — here 什么 is the subject of 让.
什么 + noun = "what kind of / which N"
Put 什么 straight in front of a noun and it becomes adjectival: "what / what kind of / which." Crucially, no measure word appears — 什么书 ("what books"), never ❌什么本书. This is what separates 什么 from 哪 (nǎ, "which"), which always demands a measure word. The reason is semantic: 什么 is open-ended (any book at all), so there's nothing to count; 哪 selects from a known, countable set, so it needs a classifier.
| 什么 + noun | Pinyin | Meaning |
|---|---|---|
| 什么书 | shénme shū | what / which books |
| 什么颜色 | shénme yánsè | what color |
| 什么时候 | shénme shíhou | when (what time / occasion) |
| 什么意思 | shénme yìsi | what meaning |
| 什么名字 | shénme míngzi | what name |
你喜欢什么书？
nǐ xǐhuan shénme shū?
What kind of books do you like? (neutral) — 什么 + 书, no measure word.
你最喜欢什么颜色？
nǐ zuì xǐhuan shénme yánsè?
What's your favorite color? (informal) — 什么颜色 asks the open set of colors.
这个词是什么意思？
zhège cí shì shénme yìsi?
What does this word mean? (neutral) — 什么意思 is one of the most useful phrases for a learner.
The indefinite 什么: "anything / nothing"
Outside a question frame, 什么 flips to an indefinite — "something / anything / nothing" — much like 谁 can mean "anyone." This is why 没什么 means "nothing much" and 什么都 + verb means "anything / everything." There's no question being asked; 什么 is just a placeholder for an unspecified thing.
没什么，我只是有点累。
méi shénme, wǒ zhǐshì yǒudiǎn lèi.
It's nothing, I'm just a bit tired. (informal) — 没什么 = 'nothing much'.
我不挑，什么都行。
wǒ bù tiāo, shénme dōu xíng.
I'm not picky, anything works. (informal) — 什么…都 sweeps over the whole set.
Common Mistakes
1. Inserting a measure word after 什么. Unlike 哪, 什么 never takes a classifier before a noun.
❌ 你喜欢什么本书？
Incorrect — 什么 takes no measure word; 本 belongs with 哪.
✅ 你喜欢什么书？
nǐ xǐhuan shénme shū?
What books do you like? — 什么 attaches straight to the noun.
2. Fronting 什么 English-style. Content questions keep statement word order; 什么 stays in the answer's slot.
❌ 什么你想吃？
Incorrect — don't move 什么 to the front the way English fronts 'what'.
✅ 你想吃什么？
nǐ xiǎng chī shénme?
What do you want to eat? — 什么 stays after the verb 吃.
3. Adding 吗 to a 什么 question. 吗 (ma) makes a yes/no question; a sentence that already has 什么 is a content question and takes no 吗.
❌ 你要什么吗？
Incorrect — 什么 already marks this as a question; 吗 clashes with it.
✅ 你要什么？
nǐ yào shénme?
What do you want? — no 吗 on a content question.
4. Using 什么 to pick from a known set. When the options are in front of you, use 哪个 ("which one"), not 什么.
❌ 这两个杯子，你要什么？
Marginal — choosing among visible options calls for 哪个, not open-ended 什么.
✅ 这两个杯子，你要哪个？
zhè liǎng ge bēizi, nǐ yào nǎ ge?
Of these two cups, which one do you want? — 哪个 selects from the set.
Key Takeaways
- 什么 (shénme) means "what" and stays in situ — in the exact slot the answer will occupy, never fronted.
- Before a noun it means "what kind of / which" and takes no measure word: 什么书, 什么颜色, 什么时候.
- Contrast with 哪 (nǎ): 什么 is open-ended (no classifier); 哪 selects from a set (classifier required).
- Content questions with 什么 never take 吗 — the question word already does the job.
- Out of a question frame, 什么 is an indefinite: 没什么 ("nothing much"), 什么都行 ("anything works").
- See the question-words overview for how all of these share one in-situ rule.

- 谁 (shéi): Who / WhomHSK 1 — 谁 (shéi, also read shuí) asks 'who' and, staying in place, works as subject (谁来了？), object (你找谁？), or possessor (谁的书？= whose book). No who/whom distinction, no fronting — as an object it stays after the verb.
- 哪 (nǎ) + Measure Word: Which OneHSK 1 — 哪 (nǎ) means 'which' and, because it selects from a known set, it obligatorily takes a measure word: 哪个 (which one), 哪本书 (which book), 哪种 (which kind) — never bare 哪. Don't confuse it with 那 (nà, 'that').
- Question Words Stay In Place (In Situ)HSK 1 — The single most important rule for Chinese wh-questions: the question word sits exactly where the answer will sit. No fronting, no do-support, no reordering — 你去哪儿？ not ❌哪儿你去？ And because the question word already asks, you never add 吗.
- Why Classifiers Are ObligatoryHSK 1 — Whenever you count a noun or point at it, Chinese demands a measure word between the number/demonstrative and the noun — 三本书, not 三书 — because a bare Chinese noun names a kind of thing, not a countable unit, so a classifier is what packages it into countable units.
