What does conspirator mean? A conspirator is someone engaged in a conspiracy—a secret plan by multiple people to do something evil or illegal.The word conspiracy can also refer to the act of making such plans—the act of conspiring—or to the group making the plans. In a legal context, conspiracy refers to an agreement by two or more people to commit a crime.In any of these cases, the people involved can be called conspirators. The word co-conspirator refers to a fellow conspirator—a conspirator conspiring with one or more other conspirators in a conspiracy. But, by itself, the word conspirator always implies that there are multiple people involved—there is never a single conspirator.A conspiracy theory is an explanation of an event that claims it was the result of a secret and often complex and evil plot by multiple conspirators. People who promote or formulate conspiracy theories often reject the standard or accepted explanation of unexplained or unusual events and claim that they are the doing of evil conspirators secretly conspiring behind the scenes.Example: This isn’t the work of one man—it’s a conspiracy, and there are more conspirators than you think!
