没用

• 拼音: méi yòng
• 汉字拆解: 没 = 氵(water) + 殳 (strike), originally meaning to sink or submerge, extended to mean not/without; 用 = pictograph of a container, meaning to use

含义

Useless; no use; pointless. Describes something or someone that serves no practical purpose.

Used very frequently in spoken Chinese. Can describe objects (没用的东西 = useless thing), actions (说了也没用 = it's no use saying it), or people (you're useless — though this is quite harsh). The opposite is 有用 (useful). Often used in frustration or dismissal. Can function as both an adjective and a predicate.

例句

1. 你说再多也没用，他不会改的。
2. 这些旧东西都没用了，扔了吧。
3. 光着急没用，得想办法解决问题。
