帮 / 帮助 / 帮忙 (bāng…) — to help | Chinese (Mandarin) Grammar

帮 (bāng) is the everyday verb for helping, and it comes with two close relatives you have to keep straight: 帮助 (bāngzhù), a slightly more formal twin that is also the noun "help," and 帮忙 (bāngmáng) "to help out," which behaves completely differently in the grammar. The trap is not the meaning — all three are "help" — it's that 帮忙 splits in two and can never take a direct object, so the beginner instinct to say *帮忙我 ("help-out me") is ungrammatical. Learn the three patterns once and the whole family clicks into place.

帮 + person (+ verb): the everyday helper

The core pattern is 帮 + person (+ what you help them do). 帮 takes the person directly, and you can tack on a second verb phrase — this is a pivotal structure, "help someone do something." This is the form you reach for in real conversation.

你能帮我吗？

nǐ néng bāng wǒ ma

Can you help me? (informal) — 帮 takes the person 我 directly.

我帮你搬桌子。

wǒ bāng nǐ bān zhuōzi

I'll help you move the table. — 帮 + 你 (person) + 搬桌子 (what I help with).

请帮我一下。

qǐng bāng wǒ yíxià

Please give me a hand. (polite) — 一下 softens it to 'a quick favor'.

帮忙 (help out): a separable verb, no object allowed

帮忙 is a separable verb (离合词, líhécí): it is built from 帮 "help" + 忙 "a busy task," so it literally already means "help-with-a-task." Because 忙 is already the object slot, you cannot bolt another object on — 帮忙我 is impossible. To name the person you help, you either switch to plain 帮 (帮我), or you split 帮忙 open and slide the person inside as a possessor: *帮我的忙 or 帮我个忙.

你能帮个忙吗？

nǐ néng bāng ge máng ma

Can you do me a favor? — 帮忙 split by 个; no person named here.

你帮我个忙好吗？

nǐ bāng wǒ ge máng hǎo ma

Would you do me a favor? — the person 我 goes INSIDE the split verb, not after it.

他帮了我一个大忙。

tā bāng le wǒ yí ge dà máng

He did me a big favor. — 了 lands on 帮, and 我 + 一个大忙 fill the split.

💡

The moment you want to say "help ME," 帮忙 splits. There is no *帮忙我 — say 帮我 (plain 帮) or 帮我的忙 / 帮我个忙 (person tucked into the split). This one habit fixes the single most common error with this verb.

帮助 (bāngzhù): the formal verb and the noun "help"

帮助 is the register-lifted version. As a verb it takes a plain object like 帮 (帮助学生), but it sounds more written and weightier — you'll meet it in news, textbooks, and formal speech far more than in casual chat. Its second job is as a noun, "help / assistance," where 帮 and 帮忙 cannot substitute.

老师经常帮助学习困难的学生。

lǎoshī jīngcháng bāngzhù xuéxí kùnnan de xuésheng

The teacher often helps students who struggle. (neutral/formal) — 帮助 + object, more written than 帮.

谢谢你的帮助。

xièxie nǐ de bāngzhù

Thank you for your help. — here 帮助 is a NOUN; you can't say *谢谢你的帮忙 in standard usage.

遇到困难可以向我们求助，我们会提供帮助。

yùdào kùnnan kěyǐ xiàng wǒmen qiúzhù, wǒmen huì tígōng bāngzhù

If you run into trouble you can ask us; we'll provide help. (formal) — 提供帮助, noun collocation.

Key collocations

Phrase	Pinyin	Meaning / note
帮我	bāng wǒ	help me — plain 帮 + person
帮忙	bāngmáng	help out — separable, no object
帮个忙	bāng ge máng	do a favor — 帮忙 split by 个
帮我的忙	bāng wǒ de máng	help me out — person inside the split
帮倒忙	bāng dàománg	"help" that makes things worse
帮助 (v.)	bāngzhù	to help (formal) — takes an object
帮助 (n.)	bāngzhù	help, assistance (a noun)

你别帮倒忙了，让我自己来。

nǐ bié bāng dàománg le, ràng wǒ zìjǐ lái

Stop 'helping' and making it worse — let me do it myself. — 帮倒忙, a fixed ironic phrase.

Choosing between them

The three overlap but split cleanly by grammar and register: 帮 for everyday spoken help (takes a person, links to a second verb), 帮忙 for "lend a hand" in general (no object, splits when a person appears), and 帮助 for formal writing and for the noun "help." For the full decision tree — including when 帮助 sounds too stiff and when only 帮忙 will do — see 帮 vs 帮助 vs 帮忙.

Common Mistakes

1. Putting an object after 帮忙. 帮忙 already contains its object (忙), so it cannot take another.

❌ 你能帮忙我吗？

Incorrect — 帮忙 can't take an object. Use 帮我 or split it: 帮我个忙.

✅ 你能帮我吗？

nǐ néng bāng wǒ ma

Can you help me? — plain 帮 takes the person.

2. Leaving 帮助 or 帮 dangling with no object. As transitive verbs they need something to help.

❌ 谢谢你帮助。

Incorrect — a verb with no object. Either add one (帮助我) or use the noun form (你的帮助).

✅ 谢谢你帮我。

xièxie nǐ bāng wǒ

Thanks for helping me. — object 我 supplied.

3. Using the noun 帮助 as if it were 帮忙. For "your help" as a noun, only 帮助 works.

❌ 谢谢你的帮忙。

Nonstandard as a noun — say 谢谢你的帮助 (noun) or 谢谢你帮忙 (verb).

✅ 谢谢你的帮助。

xièxie nǐ de bāngzhù

Thank you for your help. — 帮助 is the noun.

4. Stranding 了 or a person outside the split verb. With 帮忙, aspect markers and the person go inside.

❌ 他帮忙了我。

Incorrect — 了 and 我 can't sit outside 帮忙. Say 他帮了我个忙 / 他帮了我的忙.

✅ 他帮了我一个大忙。

tā bāng le wǒ yí ge dà máng

He did me a big favor. — 了 on 帮, person and 忙 fill the split.

Key Takeaways

帮 = the everyday spoken "help"; takes a person directly and can chain into a second verb (帮我搬东西).
帮忙 = "help out," a separable verb with a built-in object (忙); never *帮忙我 — split it (帮我个忙 / 帮我的忙) or switch to 帮.
帮助 = the formal verb and the noun "help / assistance"; use it in writing and wherever you need a noun (提供帮助, 你的帮助).
Aspect and the person both go inside 帮忙: 帮了我个忙, not *帮忙了我.
