Usage of 自从
The word 自从 (zì cóng) is a conjunction used to indicate the starting point of an action or state continuing up to the present. It is often translated as "since" in English and is followed by a time phrase or event.
Common Collocations
- 自从 + [time/event], + [result or ongoing action]
Nuances and Usage Notes
自从 emphasizes the starting point of a change or continuous state. It is typically used in formal or neutral contexts and often appears at the beginning of a sentence or clause.
Unlike 以后 (yǐhòu, "after"), 自从 stresses the origin point rather than the subsequent time frame.
Common Confusions
Do not confuse 自从 with 从 (cóng) alone, which means "from" but does not imply continuation. 自从 always introduces a temporal clause indicating a starting point for an ongoing situation.
Summary
Use 自从 when you want to express "since (a certain time or event)" to highlight when something began and has continued until now. It is a useful word for storytelling, describing changes, or explaining ongoing habits or states.
