不用 (don't need to)

• 拼音: bùyòng
• 结构: Subject + 不用 + Verb Phrase
• 汉字拆解: 不 = simple negative character; 用 = pictograph of a fence or enclosure, extended to mean 'to use'

含义

The phrase 不用 means 'don't need to' or 'there's no need to.' It negates necessity and is commonly used to tell someone they can skip an action because it is unnecessary.

Unlike 不要 (don't), which is a command or prohibition, 不用 is about necessity — it tells someone an action is not required, often as a reassurance or polite gesture. For example, 不用谢 (no need to thank me) is a standard polite response. 不用 is the negation of 用 in its sense of 'to need,' and it functions similarly to 不必, though 不必 is more formal. In daily speech, 不用 is far more common than 不必. It can be used independently as a short response: 不用了 (no need). The pattern is straightforward and appears across all contexts.

例句

1. 明天不用上班，可以睡个懒觉。

3. 这件事不用你管，我自己来。

错误说法

起源与历史

不 means 'not' and 用 means 'to use' or 'to need.' The combination 不用 as 'no need to' developed from the sense of 'no use in doing,' which evolved into a straightforward negation of necessity.
