为止

为止 is an adverb meaning 'until' or 'up to a certain point.' It indicates the end of a period or action, often used to show that something continues until a specific time or event occurs.

The character 为 (wéi) originally meant 'to be' or 'for,' while 止 (zhǐ) means 'to stop' or 'halt.' Together, they convey the idea of reaching a limit or conclusion, similar to the English concept of 'until.'

为止 is commonly used in daily speech and writing to mark the endpoint of an action or time frame. For example, it can be used in phrases like '直到晚上为止' (until evening) or '到明年为止' (until next year). It is often paired with time expressions or events to clarify the scope of an action or condition.
