Usage and Meaning
The word 不许 (bùxǔ) is a strong negation meaning "not allowed" or "forbidden." It is used to explicitly prohibit an action or behavior. It often appears in authoritative or formal contexts, such as rules, instructions, or commands.
Common Collocations
- 不许 + verb: to forbid doing something (e.g., 不许吸烟 - no smoking)
- 不许 + person + verb: to forbid someone from doing something (e.g., 不许学生迟到 - students are not allowed to be late)
Pragmatic Notes
Using 不许 conveys a clear and firm prohibition. It is stronger than simply saying 不可以 or 不能. It often implies that there will be consequences if the rule is broken. It is common in spoken commands and written rules.
Avoiding Confusion
Do not confuse 不许 with 不许可 (permission), which is a noun phrase meaning "permission." 不许 is a verb phrase meaning "not permit." Also, 不许 is more forceful than 不让 or 不准, which also mean "not allow" but can be softer or more formal.
Summary
Use 不许 when you want to clearly and firmly forbid an action, especially in contexts where authority or rules are involved.
