Usage of 为止
The phrase 为止 (wéizhǐ) is used to indicate the endpoint of a time period or an action. It often follows a time expression or a point in a process to mark the limit or boundary up to which something happens.
Common contexts
It is frequently used in formal and informal speech to specify deadlines, durations, or limits, such as "until now," "up to this point," or "by a certain time."
Collocations and patterns
- 到...为止: indicates 'up to' a certain time or point, e.g., 到今年年底为止 (up to the end of this year).
- 从...为止: used to mark the starting point continuing to the endpoint, e.g., 从早上工作为止 (working from morning until).
Nuances
Using 为止 emphasizes the boundary or limit of an action or state. It differs from just using time expressions alone by explicitly marking the endpoint. Avoid confusing it with 直到, which also means 'until' but often focuses more on the action continuing until a point rather than marking the endpoint itself.
