How does Chinese 别 bié differ from 不 bù 要 yào in prohibitive force, and why do learners confuse them?

别 bié is the casual, everyday prohibition: 别 bié 走 zǒu ！(Don't go!) It is short, soft, and natural. 不 bù 要 yào is more emphatic or formal: 不 bù 要 yào 走 zǒu ！(Do not go!) 禁 jīn 止 zhǐ and 不 bù 许 xǔ are official/legal bans. English learners often use 不 bù 要 yào for all prohibitions, sounding stiff or parental. Spanish speakers learning Chinese must learn that 别 bié is the default, while 不 bù 要 yào carries extra weight. English 'don't' covers all registers, so the Chinese gradation is unfamiliar.

Prohibitives & Negative Commands

How languages express commands not to do something in Spanish, English and Chinese.

Compare languages

Prohibitives are commands to refrain from an action. Spanish uses no + subjunctive or imperatives with no. English uses don't + imperative. Chinese uses 不bù要yào/别bié/禁jīn止zhǐ/不bù许xǔ.

Overview

Prohibitives express commands not to perform an action. They range from polite requests to strict legal prohibitions.

Spanish: Negative imperatives use the present subjunctive forms. No vayas is the standard negative command. Public signs use nominalized forms (prohibido fumar). Softening uses the conditional or subjunctive in independent clauses.
English: Uses don’t + base verb for almost all prohibitives. No person distinctions. Public signs use gerunds (no smoking). Softening uses modal remoteness (you might not want to).
Chinese: Uses 别bié for casual prohibitions, 不bù要yào for more emphatic ones, 不bù许xǔ/禁jīn止zhǐ for strong/official bans. 千qiān万wàn别bié adds urgency.

Spanish

No + subjunctive (standard prohibition)

Spanish negative commands use the present subjunctive:

Subject	Affirmative	Negative
tú	¡Ven!	¡No vengas!
usted	¡Venga!	¡No venga!
vosotros	¡Venid!	¡No vengáis!
ustedes	¡Vengan!	¡No vengan!
nosotros	¡Vamos!	¡No vayamos!

Examples:

¡No toques eso! (Don’t touch that!)
¡No digas eso! (Don’t say that!)
¡No te preocupes! (Don’t worry!)
¡No lo hagas! (Don’t do it!)

First person negative (let’s not)

¡No vayamos! (Let’s not go!)
¡No comamos aquí! (Let’s not eat here!)

Impersonal prohibitions

Official/formal:

Prohibido fumar. (Smoking prohibited.)
Prohibido el paso. (No entry.)
No se permite la entrada. (Entry not permitted.)
Está prohibido aparcar. (Parking is prohibited.)
Vetado el paso. (Entry forbidden.)

Se + verb:

Nunca + negative command

¡Nunca digas eso! (Never say that!)

Negative command with pronoun placement

In negative commands, pronouns precede the verb:

¡No me digas! (Don’t tell me!)
¡No lo toques! (Don’t touch it!)
¡No se lo des! (Don’t give it to him!)

English

Don’t + imperative (standard)

English uses don’t for all persons in negative commands:

Don’t go!
Don’t touch!
Don’t be late!
Don’t worry!
Don’t do it!

Let’s not (first person plural)

Let’s not go.
Let’s not worry about it.

No entry.
No swimming.
No pets allowed.
No unauthorized personnel.

You must not smoke. (strong prohibition)
You may not enter. (permission denied)
You cannot park here. (impossibility = prohibition)
You are not allowed to smoke.
You are forbidden to enter.

Softened prohibitions

You might not want to do that.
I’d avoid that if I were you.
It would be better if you didn’t.
I wouldn’t do that if I were you.
Perhaps you shouldn’t…
I’m not sure you should…

Never + imperative

Never touch that!
Never say that again!
Never go there alone!

Third person (let + not)

Don’t let him go. / Let him not go. (archaic)
Don’t let it happen.

Chinese

别bié (casual prohibition)

别bié is the most common spoken prohibition, softer and more natural than 不bù要yào:

别bié走zǒu！(Don’t go!)
别bié碰pèng！(Don’t touch!)
别bié担dān心xīn！(Don’t worry!)
别bié说shuō了le！(Stop talking!)

不bù要yào (emphatic prohibition)

不bù要yào is more emphatic or formal than 别bié:

不bù要yào走zǒu！(Don’t go! — stronger)
不bù要yào迟chí到dào！(Don’t be late!)
不bù要yào忘wàng了le！(Don’t forget!)

不bù许xǔ/不bù准zhǔn/不bù能néng (strong/official prohibition)

不bù许xǔ抽chōu烟yān！(No smoking!)
不bù准zhǔn停tíng车chē！(No parking!)
不bù能néng进jìn去qù！(Can’t enter!)

禁jīn止zhǐ (formal/legal prohibition)

禁jìn止zhǐ吸xī烟yān！(Smoking prohibited!)
禁jìn止zhǐ停tíng车chē！(Parking prohibited!)
禁jìn止zhǐ入rù内nèi！(Entry prohibited!)

千qiān万wàn别bié忘wàng了le！(Whatever you do, don’t forget!)

不bù要yào/别bié + 了le (cessative)

别bié吃chī了le！(Stop eating!)
不bù要yào说shuō了le！(Stop talking!)

Note: 了le here marks cessation of an ongoing action.

Frequently Asked Questions

Why does Spanish use the subjunctive in negative commands but the indicative in affirmative ones?

Spanish affirmative commands use the imperative mood: *¡Ven!* (Come!). Negative commands use the present subjunctive: *¡No vengas!* (Don't come!). This asymmetry is unusual cross-linguistically. English uses the base form in both cases: 'Come!' and 'Don't come!' Chinese uses the same verb form with different negation markers: <ruby>来<rt>lái</rt></ruby>！(Come!) and <ruby>别<rt>bié</rt></ruby><ruby>来<rt>lái</rt></ruby>！(Don't come!). An English speaker learning Spanish must learn two different verb forms for what feels like a single negation operation. A Chinese speaker faces the same challenge, compounded by the fact that Chinese has no concept of mood inflection at all.

How does Chinese <ruby>别<rt>bié</rt></ruby> differ from <ruby>不<rt>bù</rt></ruby><ruby>要<rt>yào</rt></ruby> in prohibitive force, and why do learners confuse them?

<ruby>别<rt>bié</rt></ruby> is the casual, everyday prohibition: <ruby>别<rt>bié</rt></ruby><ruby>走<rt>zǒu</rt></ruby>！(Don't go!) It is short, soft, and natural. <ruby>不<rt>bù</rt></ruby><ruby>要<rt>yào</rt></ruby> is more emphatic or formal: <ruby>不<rt>bù</rt></ruby><ruby>要<rt>yào</rt></ruby><ruby>走<rt>zǒu</rt></ruby>！(Do not go!) <ruby>禁<rt>jīn</rt></ruby><ruby>止<rt>zhǐ</rt></ruby> and <ruby>不<rt>bù</rt></ruby><ruby>许<rt>xǔ</rt></ruby> are official/legal bans. English learners often use <ruby>不<rt>bù</rt></ruby><ruby>要<rt>yào</rt></ruby> for all prohibitions, sounding stiff or parental. Spanish speakers learning Chinese must learn that <ruby>别<rt>bié</rt></ruby> is the default, while <ruby>不<rt>bù</rt></ruby><ruby>要<rt>yào</rt></ruby> carries extra weight. English 'don't' covers all registers, so the Chinese gradation is unfamiliar.

Why do English public signs say 'No smoking' while Spanish signs say 'Prohibido fumar' and Chinese signs say <ruby>禁<rt>jīn</rt></ruby><ruby>止<rt>zhǐ</rt></ruby><ruby>吸<rt>xī</rt></ruby><ruby>烟<rt>yān</rt></ruby>?

English prefers nominalization in public signs: 'No smoking' (gerund as noun) rather than 'Do not smoke.' Spanish prefers a full sentence or participle: *Prohibido fumar* (Prohibited to smoke) or *Se prohíbe fumar* (It is prohibited to smoke). Chinese uses a formal verb compound: <ruby>禁<rt>jīn</rt></ruby><ruby>止<rt>zhǐ</rt></ruby> (prohibit-stop) + verb. These differences reflect register conventions, not grammar. An English speaker translating literally into Spanish will produce *No fumando*, which does not exist. A Spanish speaker translating literally into English will produce 'It is prohibited to smoke,' which is comprehensible but unnatural on a sign. Each language has fixed formulae for public prohibitions that must be learned as phrases.
