Usage of 直到
'直到' is a preposition used to indicate the time or condition up to which an action or state continues. It often marks the endpoint of a duration or the moment when something changes.
Common contexts
It frequently appears in sentences describing time limits or conditions, such as waiting for an event to happen or continuing an action until a certain point.
Typical collocations
- 直到 + time point: to specify the exact time something lasts until.
- 直到 + clause: to indicate the condition or event that must occur before something else happens.
Nuances
Using '直到' emphasizes the continuation or persistence of an action or state up to a particular moment. It often implies that something does not happen before that point.
Common confusion
Do not confuse '直到' with '到' alone; '直到' stresses the duration or limit up to a point, while '到' can simply mean 'arrive' or 'reach' without the temporal continuation nuance.
