为 (for / on behalf of)

• 拼音: wèi
• 结构: Subject + 为 + Beneficiary + Verb / Adjective

含义

The preposition 为 (wèi) means 'for' or 'on behalf of' and is used to indicate the beneficiary of an action. It introduces the person or party that the action is performed for, placing them before the verb.

As a preposition meaning 'for,' 为 is more formal than 给 and is preferred in written Chinese, official statements, and elevated speech. While 给 is the everyday spoken equivalent, 为 carries a sense of purpose, dedication, or service. It frequently appears in phrases expressing sacrifice, effort, or contribution on someone's behalf. 为 can also combine with abstract nouns to express purpose (为了 + goal). In contrast to 替 which implies substitution ('in place of'), 为 emphasises benefiting the other party. Note that 为 has two pronunciations: wèi (for/on behalf of) and wéi (to be/to act as), and learners must distinguish between these.

例句

1. 父母一辈子都在为子女操劳。
