'Circa' is a Latin word that means "around" or "approximately." It is used to express an estimated time period in history or before a certain event, like a date or a year. For instance, if you know that World War II happened around the 1940s, you could say "World War II started circa 1940." It's often used in historical or academic writing to signify a general timeframe when a fact or event happened.
