帮 vs 帮助 vs 帮忙 (bāng vs bāngzhù vs bāngmáng): helping verbs in Chinese
帮 and 帮助 are transitive verbs that take a direct object (the person or task being helped), while 帮忙 is an intransitive verb-object compound meaning “to do a favor” and cannot take a direct object. To specify who is helped with 帮忙, you must either insert the person between 帮 and 忙 (帮某人的忙) or use a preposition like 给 (给某人帮忙).
All three words convey 'to help', but they differ in transitivity and formality. 帮 is the colloquial transitive verb used in everyday speech; it directly takes a person or task as object. 帮助 is a more formal equivalent, also transitive, and can be used as a noun meaning 'help/assistance'. 帮忙 is a verb‑object compound (帮 'help' + 忙 'busy/favor') that functions as an intransitive predicate: it cannot take a direct object. To include the person helped with 帮忙, you separate the compound (帮他的忙) or use a prepositional phrase (给他帮忙).
When to use each
Use 帮 in informal spoken Chinese when you need a transitive verb. It directly takes a person or a task as its object, e.g., 帮我 (help me), 帮他搬东西 (help him move things). It is the most common choice in daily conversation.
Use 帮助 in formal writing, speeches, or when you want a more polite/serious tone. It is transitive like 帮 and can take a person or task as object. 帮助 can also be a noun meaning 'help' or 'assistance'.
Unlike 帮, 帮助 cannot be used with a directly attached 忙-like element; it is always a single unit.
Use 帮忙 to express 'to help out' or 'to do a favor' without specifying the person or task. It is a verb‑object compound and cannot take a direct object. To specify who is helped, either split the compound (帮+person+的+忙) or use the preposition 给 (给+person+帮忙). You can also use 帮忙 standalone (我来帮忙) or with modifiers (帮个忙).
Since 忙 is a nominal element, 帮忙 can take aspect markers (帮过忙, 帮帮忙) and degree complements, but never a direct object.

Common mistakes
- Using 帮忙 with a direct object: ✗ 帮忙我 → ✓ 帮我 or 帮助我 or 给我帮忙.
- Using 帮 in formal writing when 帮助 is more appropriate (e.g., in official documents).
- Forgetting to separate 帮忙 when specifying the person: ✗ 帮忙他 → ✓ 帮他的忙 or 给他帮忙.
- Using 帮助 in very casual commands where 帮 sounds more natural (e.g., 帮我一下, not 帮助我一下).
- Treating 帮忙 as a two‑syllable transitive verb: cannot say *我帮忙他.
