What is the Latin term for a conspiracy or plot?

The term "coniuratio" in Latin specifically denotes a conspiracy or plot, especially one formed by a group of people acting together with a secretive or malevolent intent. This word derives from the root "coniurare," which means to swear together, indicating a formal agreement or pact among conspirators.

In Roman contexts, "coniuratio" often referred to secret plans against individuals or the state, thereby having a significant connotation in political and social discourse. Its use aligns with Cicero's own writings, where themes of conspiracies, political plots, and alliances are prevalent, reinforcing the importance of understanding this term in the study of Latin literature and history.

The other choices represent different meanings: "particeps" refers to a participant or accomplice; "furor" indicates madness or rage; and "abutor" means to abuse or misuse something. None of these terms convey the specific notion of a conspiracy or plot as effectively as "coniuratio" does.
