Three of the first words a learner meets — 帮, 帮助, 帮忙 — all mean "help," and they are not interchangeable synonyms you can pick by feel. What separates them is pure grammar: how each one attaches to a person and a task. 帮 wants a person and the thing to do — help someone do something. 帮助 is the heavier, more formal verb that can stand on its own with an object or even work as a noun ("your help"). 帮忙 looks like a verb but is secretly a verb-object compound (离合词) — 帮 "help" plus 忙 "a busy task" — which means it is already "full up" and cannot take another object behind it. That one structural fact is behind the single most common error here: *帮忙我. This page sorts the three by their grammar; the everyday spoken uses of "help me" are gathered on help me — 帮忙.
The decision grid
| Word | Structure | Takes an object? | Example |
|---|---|---|---|
| 帮 (bāng) | 帮 + person + verb | yes — a person, then the task | 帮我搬桌子 (help me move the table) |
| 帮助 (bāngzhù) | verb or noun | yes — object directly; also a noun | 帮助学生 / 你的帮助 (help students / your help) |
| 帮忙 (bāngmáng) | 离合词 (帮 + 忙) | NO direct object — it splits instead | 帮个忙 / 帮我一个忙 (lend a hand / do me a favor) |
帮: help someone DO something
帮 is the workhorse of casual speech. Its natural shape is 帮 + person + verb phrase — you name who you're helping and what they're doing. It's quick, warm, and everywhere in daily life.
你能帮我搬一下桌子吗？
nǐ néng bāng wǒ bān yíxià zhuōzi ma?

帮助: the fuller, formal verb — and a noun
帮助 is 帮's dressed-up relative. As a verb it takes an object directly and suits formal, abstract, or written contexts — helping students, helping the poor, helping a cause. Uniquely, it also works as a noun: "help / assistance."
老师很耐心地帮助每一个学生。
lǎoshī hěn nàixīn de bāngzhù měi yí ge xuésheng

帮忙: lend a hand — but hold no object
帮忙 means "help out, lend a hand," and it is intransitive: it stands alone or splits, but it never takes a following object. When you need to name the person, you either switch to 帮 (帮我) or split the compound and insert the person: 帮 + 我 + 一个 + 忙. The 离合词 also splits for 了, measure phrases, and question words — a pattern shared across separable verbs.
你能帮个忙吗？我一个人搬不动。
nǐ néng bāng ge máng ma? wǒ yí ge rén bān bu dòng
Can you lend a hand? I can't move it by myself. (informal) — 帮个忙, split by 个.
大家都来帮忙，很快就干完了。
dàjiā dōu lái bāngmáng, hěn kuài jiù gàn wán le

zhè cì zhēnshì máfan nǐ le, bāng le wǒ yí ge dà máng
I really put you out this time — you did me a huge favor. (informal) — split wide open: 帮 + 了 + 我 + 一个大 + 忙.
不好意思，我帮不上什么忙。
bù hǎoyìsi, wǒ bāng bu shàng shénme máng
Sorry, I'm not able to be of much help. (informal) — potential complement 帮不上…忙, still split.
Common Mistakes
1. Giving 帮忙 a direct object. 帮忙 already holds 忙; use 帮 + person, or split it as 帮…忙.
❌ 你能帮忙我吗？
Wrong — 帮忙 can't take an object; say 你能帮我吗 or 你能帮我一个忙吗？
✅ 你能帮我一个忙吗？
nǐ néng bāng wǒ yí ge máng ma?
Can you do me a favor? — the person 我 goes INSIDE the split 帮…忙.
2. Treating 帮 as a noun. "Your help" is 帮助, not 帮; 帮 is only a verb.
❌ 谢谢你的帮。
Wrong — the noun is 帮助: 谢谢你的帮助。
✅ 谢谢你的帮助，我一个人真做不完。
xièxie nǐ de bāngzhù, wǒ yí ge rén zhēn zuò bu wán
Thanks for your help — I really couldn't finish alone. — noun 帮助.
3. Using formal 帮助 for a quick everyday favor. For a small hands-on task, 帮 is what people actually say; 帮助 sounds stiff.
❌ 你能帮助我搬桌子吗？
Grammatical but stiff for a small task — natural speech is 你能帮我搬桌子吗？
✅ 你能帮我搬桌子吗？
nǐ néng bāng wǒ bān zhuōzi ma?
Can you help me move the table? — everyday 帮 for a quick favor.
4. Splitting 帮忙 wrongly when there's an object. The 了 and the person all go inside the compound, not after 帮忙.
❌ 他帮忙了我一个大忙。
Wrong — 了 and the object go inside: 他帮了我一个大忙。
✅ 他帮了我一个大忙，我得请他吃饭。
tā bāng le wǒ yí ge dà máng, wǒ děi qǐng tā chī fàn
He did me a big favor — I ought to treat him to a meal. — the split holds 了, 我, and 一个大.
Key Takeaways
- 帮 = help someone DO something: 帮 + person + verb (帮我搬桌子) — the everyday spoken choice.
- 帮助 = a fuller, more formal verb that takes an object directly, and can also be a noun (你的帮助).
- 帮忙 = a 离合词 meaning "lend a hand" — intransitive, so it never takes a following object.
- To say "help me" with 帮忙, split it: 帮我一个忙; the person and 了 go inside, never after (*帮忙我).
- Use 帮 for quick favors, 帮助 for formal or abstract help and for the noun "help."

- Asking for Help: 帮我/帮忙HSK 2 — To ask for help you frame the verb 帮 politely: 帮我 + verb ('help me [do]' — 帮我看看) for a named task, or the separable 帮忙 / 帮个忙 ('give me a hand / do me a favor') for help in general. The strategy is wrapping either in a modal question — 你能帮我…吗？麻烦你帮个忙 — so you're asking, not ordering.
