Definition: The word "c circa" comes from the Latin word 'circa,' which means around, within a certain period of time, or in this case, between two events. Here's its definition: 1. Within a period of time: This phrase indicates that something was happening before another event happened at that time. 2. Between two events: It is used to describe the relationship between two events rather than directly comparing them as "between." For example, if you say "I'm going to do some work around 3 p.m," this means that the work will be done in about three hours before you finish it. In summary: - Within a period of time: Something happened before another event. - Between two events: The relationship between two events.
