怎么 (zěnme) is the Mandarin "how" — but it stretches further than English "how," reaching into "how come / why (with surprise)." It always sits before the verb, never at the end, and it has two readings: manner ("in what way, by what means") and cause ("how come," carrying a note of surprise or concern). Learning to hear which reading is intended — and to keep 怎么 apart from the neutral 为什么 ("why") and the standalone 怎么样 ("how is it") — is the whole job of this page.
Manner 怎么: "how / by what means"
The core use is asking how an action is done — by what method, in what manner, using what means. 怎么 goes right in front of the verb, and the answer names a method: 坐车 ("by bus / car"), 用筷子 ("with chopsticks"), 一笔一笔地 ("stroke by stroke"). Because the answer is a way-of-doing, manner-怎么 pairs naturally with verbs of action, writing, saying, cooking, and getting somewhere.
这个字怎么写？
zhège zì zěnme xiě?
How do you write this character? (neutral) — 怎么 before 写; the answer is a method of writing.
你怎么去学校？
nǐ zěnme qù xuéxiào?
How do you get to school? (informal) — asks the means; answer '坐地铁 / 走路'.
这个词用中文怎么说？
zhège cí yòng Zhōngwén zěnme shuō?
How do you say this word in Chinese? (neutral) — a survival phrase; 用中文 sets the means, 怎么说 asks the how.
米饭怎么做？
mǐfàn zěnme zuò?
How do you cook rice? (informal) — manner 怎么 before 做, asking the method.
Cause 怎么: "how come" (with surprise)
Put 怎么 in front of a negated verb, or before something unexpected, and it flips to a cause reading — "how come, why on earth." Unlike the neutral 为什么 ("for what reason"), this 怎么 carries feeling: surprise, puzzlement, mild reproach, or concern. 你怎么不吃？ isn't a neutral request for reasons — it signals "I'm surprised you're not eating." This emotional coloring is exactly why 怎么 and 为什么, though overlapping, are not interchangeable.
你怎么不吃？
nǐ zěnme bù chī?
How come you're not eating? (informal) — surprise/concern, not a neutral 'why'.
你怎么现在才来？
nǐ zěnme xiànzài cái lái?
How come you only got here now? (informal) — mild reproach; 才 underlines 'later than expected'.
The set phrase 怎么了？ (zěnme le?) is the everyday "what's wrong? / what happened?" — you say it when you notice something is off. And 怎么这么… (zěnme zhème…, "how come so…") is an exclamation of surprise at a degree, not really a question at all:
怎么了？你看起来不太高兴。
zěnme le? nǐ kànqǐlai bú tài gāoxìng.
What's wrong? You don't look too happy. (informal) — 怎么了 checks in on someone; note 不 → bú before the fourth-tone 太.
怎么这么贵！我不买了。
zěnme zhème guì! wǒ bù mǎi le.
How can it be this expensive?! I'm not buying it. (informal) — 怎么这么 voices surprise at the degree.
| Pattern | Example | Reading |
|---|---|---|
| 怎么 + 动词 (manner) | 怎么写 | how / by what method |
| 怎么 + 去 (means) | 怎么去 | how / by what means |
| 怎么 + 不/没 + 动词 | 怎么不吃 | how come (surprise) |
| 怎么了 | 怎么了？ | what's wrong |
| 怎么这么… | 怎么这么贵 | how come so… (exclamation) |
怎么 vs 怎么样: two different words
Don't let the shared 怎么 fool you: 怎么样 (zěnmeyàng) is a separate word meaning "how is it / how about," and it does not go before a verb — it stands alone as a predicate or trails the thing being judged. 这个菜怎么样？ ("how's this dish?") asks for an evaluation; 你最近怎么样？ ("how've you been?") asks after someone. You cannot swap them: manner 怎么 needs a following verb, while 怎么样 needs no verb. Full treatment on the 怎么样 page.
你最近怎么样？
nǐ zuìjìn zěnmeyàng?
How have you been lately? (informal) — 怎么样 stands alone; you couldn't use bare 怎么 here.
Common Mistakes
1. Confusing manner-怎么 with 为什么. Use 怎么 for "by what means," 为什么 for a neutral "for what reason."
❌ 你为什么去学校？（想问坐什么车）
Wrong word — 为什么 asks the reason; for 'by what means' use 怎么去学校.
✅ 你怎么去学校？
nǐ zěnme qù xuéxiào?
How do you get to school? — 怎么 asks the means of transport.
2. Putting 怎么 after the verb. 怎么 always precedes the verb.
❌ 这个字写怎么？
Incorrect — 怎么 goes before the verb: 这个字怎么写？
✅ 这个字怎么写？
zhège zì zěnme xiě?
How do you write this character? — 怎么 before 写.
3. Using 怎么 where you need 怎么样. For "how is it / how about," use the standalone 怎么样.
❌ 这个菜怎么？
Incomplete — 怎么 needs a following verb; for 'how's this dish?' say 怎么样.
✅ 这个菜怎么样？
zhège cài zěnmeyàng?
How's this dish? — 怎么样 stands alone as the predicate.
4. Adding 吗 to a 怎么 question. 怎么 already marks a content question, so no 吗.
❌ 你怎么去吗？
Incorrect — 怎么 already makes it a question; 吗 doesn't belong.
✅ 你怎么去？
nǐ zěnme qù?
How are you getting there? — no 吗 on a content question.
Key Takeaways
- 怎么 (zěnme) goes before the verb and has two readings: manner ("how, by what means") and cause ("how come," with surprise).
- Manner 怎么 answers with a method (坐车, 用筷子); it pairs with 写, 说, 做, 去.
- The cause reading — 怎么不…, 怎么了？, 怎么这么… — carries surprise, concern, or reproach, unlike neutral 为什么.
- 怎么样 is a different word ("how is it / how about"): it stands alone, takes no following verb, and can't be swapped with 怎么.
- A content question with 怎么 never takes 吗.

- 为什么 (wèishénme): WhyHSK 2 — 为什么 (wèishénme), literally 'for what', asks a neutral 'why' and sits after the subject, before the verb — 你为什么不来？ — with the answer framed by 因为 (yīnwèi) 'because'.
- 怎么样 (zěnmeyàng): How About / How Is ItHSK 2 — 怎么样 (zěnmeyàng) asks for an evaluation ('how is it?') or floats a suggestion ('how about…?') and sits at the end as a stand-alone predicate — 你怎么样？, 这个怎么样？ — with no 是 and no other verb.
- 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.
- 用 (yòng): With / Using (Instrument)HSK 1 — 用 (yòng) marks the tool or method 'with / using', sitting before the main verb: 用筷子吃饭 (eat with chopsticks), 用中文写 (write in Chinese), 用手机付钱 (pay with a phone). The instrument phrase always comes first: Subject + 用 + tool + Verb. Keep instrumental 'with' (用) separate from comitative 'with a person' (跟/和).
