Core Meaning and Usage
The word "能" (néng) primarily functions as a modal verb expressing ability or capability, similar to "can" or "be able to" in English. It indicates that someone has the skill, power, or possibility to do something.
Politeness and Permission
Besides ability, "能" is also used to ask for or grant permission politely, often in questions like "你能帮我吗？" (Can you help me?). This usage is common in everyday conversation and is less formal than other permission expressions.
Common Collocations
- 能 + Verb: Expresses ability (e.g., 能说, 能做)
- 能不能 + Verb: Polite question asking if something is possible
- 不能: Negative form meaning "cannot"
Usage Notes
"能" is often interchangeable with "会" when referring to learned skills, but "能" emphasizes capability or permission, while "会" focuses on learned ability. For example, "我能开车" (I am able to drive) vs. "我会开车" (I know how to drive).
