Usage of 能否
The phrase 能否 is a formal way to ask whether something is possible or whether someone is able to do something. It is often used in polite requests or inquiries, especially in written or formal spoken Chinese.
Common contexts
- Asking for permission or ability: "你能否帮我？" (Can you help me?)
- Inquiring about feasibility or possibility: "能否完成任务？" (Is it possible to complete the task?)
- Confirming attendance or participation: "能否参加会议？" (Can you attend the meeting?)
Collocations and patterns
- 能否 + verb phrase: used to ask if an action can be done.
- 请 + 能否 + verb phrase: polite request for confirmation.
Nuances
Using 能否 instead of just 能 adds a more formal and sometimes more tentative tone. It is less direct than simply asking "你能...吗？" and is common in business, official, or polite contexts.
Common confusion
Don't confuse 能否 with 还是 (or) or 不能 (cannot). 能否 specifically asks about the possibility or ability, not a choice or negation.
