怎么 vs 多 (zěnme vs duō): how (manner vs degree)
怎么 (zěnme) asks about the manner, method, or reason of an action (e.g., 'how to do it'), while 多 (duō) followed by an adjective asks about the degree or extent (e.g., 'how big', 'how far'). The two are not interchangeable: 怎么 cannot measure a quality, and 多 cannot ask for a method. Knowing which one to use depends on whether you are questioning the process or the quantity of a property.
The Chinese words 怎么 (zěnme) and 多 (duō) both translate to 'how' in English, but they operate in entirely different grammatical domains. 怎么 asks about the manner, method, or reason behind an action or state — it answers questions like 'how to do something' or 'how come?'. 多, on the other hand, must be followed by a scalar adjective (e.g., 大 'big', 远 'far', 高 'tall') and asks about the degree or measurement of that property. The key to choosing correctly is to identify whether you are inquiring about a procedure (use 怎么) or about a quantifiable extent (use 多). Overlap is rare and usually ungrammatical.
When to use each
Use 怎么 when asking about the way something is done, the means of achieving something, or the reason behind an action. It can stand alone as a question word or modify a verb. For example, asking 'How do you go to school?' requires 怎么 because you want the method (e.g., by bus). 怎么 can also appear in sentences like '怎么会这样？' (How could this happen?) to express surprise or ask for a cause.
Use 多 directly before a limited set of scalar adjectives (e.g., 大, 远, 高, 长, 重, 快, 贵, etc.) to ask about the degree or measurement of that quality. It always requires an adjective immediately after it, and not a verb. For example, '多远？' means 'How far?', and '多大？' means 'How big?'. 多 cannot be used with a verb alone; if you want to ask 'how much' in terms of quantity (e.g., money), you use 多少 rather than 多 alone.
Because 多 itself means 'many/much', the combination 多 + adjective may be misinterpreted by beginners as 'very adjective' (e.g., 多大 could be misread as 'very big' instead of 'how big'). The interrogative meaning depends on context and intonation.
At a glance
| 怎么 | 多 | |
|---|---|---|
| Core meaning | Asks about manner, method, or reason | Asks about the degree of an adjective |
| Grammatical requirement | Can stand alone or modify a verb | Must be immediately followed by a scalar adjective |
| Common answers | A verb phrase describing method (e.g., 坐地铁) | A specific measurement or value (e.g., 十公里) |
| Negation pattern | 不怎么会 + verb = not very good at doing something | Not applicable (多 is not used in negation for degree questions) |
| Can it mean 'why'? | Yes, in some contexts (e.g., 怎么没来？) | No |
Examples
- 怎么你怎么去学校？Nǐ zěnme qù xuéxiào?How do you go to school?Manner question: the answer describes the method (e.g., by bus).
- 多从这里到公园多远？Cóng zhèlǐ dào gōngyuán duō yuǎn?How far is it from here to the park?Degree question: 远 is a scalar adjective; answer gives a distance.
- 怎么这个问题怎么回答？Zhège wèntí zěnme huídá?How do you answer this question?Method: the answer explains a procedure.
- 多你多大？Nǐ duō dà?How old are you?Degree question using the adjective 大 (old in age context).
- 多这座山有多高？Zhè zuò shān yǒu duō gāo?How tall is this mountain?Degree: 高 is a scalar adjective; 有 is optional before 多.
Common mistakes
- Using 怎么 to ask about degree, like '怎么大？' instead of '多大？' — this is ungrammatical and sounds like 'How, big?'.
- Using 多 alone before a verb (e.g., '多去？' to ask 'how to go?') — this is incorrect; use 怎么 for method.
- Forgetting the adjective after 多 (e.g., '多？' without a context) — the adjective is mandatory for a specific degree question.
- Confusing 多 + adjective with 多少 (how many/much) — 多少 is used for quantities of countable items or money, not for scalar properties.
FAQ
- When do I use 怎么 vs 多 to ask 'how'?
- Use 怎么 when you want to know the manner, method, or reason behind an action (e.g., 怎么去 'how to go'). Use 多 + adjective when you want to know the degree or measurement of a quality (e.g., 多大 'how big', 多远 'how far'). They are not interchangeable.
- Can 怎么 ever mean 'how much'?
- No, 怎么 does not ask about degree or quantity. For 'how much' in terms of price, use 多少钱; for 'how many', use 多少个; for degree of an adjective, use 多 + adjective. 怎么 can mean 'why' in some contexts (e.g., 怎么还不来？ 'Why aren't you here yet?').
- Why can't I say '怎么远？' to mean 'how far?'
- Because 怎么 is used for methods or reasons, not for measuring properties. To ask 'how far,' you must use the structure 多 + adjective: 多远. Saying '怎么远' would be understood as 'How (is it) far?' which is nonsensical or might be interpreted as 'Why far?' in a nonstandard way.
- Is 多 always used with adjectives? Can it be used with verbs?
- No, when asking about degree, 多 must be followed by a scalar adjective (like 大, 小, 快, 慢, 重, etc.). It cannot directly precede a verb. For example, '多跑？' is not a question about degree; that would mean 'run more' (imperative). For questions about verb manner, always use 怎么.
