What does delation mean?
Delation is a formal term denoting the act of informing against or accusing someone before a legal or governmental authority, especially through secret or malicious denunciation. Derived from the Latin verb deferre, meaning "to carry down" or "to bring before," the word entered English in the early seventeenth century and was long used in Roman-law contexts, where a delator was a professional informer who brought accusations — often for reward. In Scots law, delation carries a distinct technical meaning: the transfer of a case from one court or judge to another. Today the word appears mainly in historical and scholarly discussions of surveillance societies, from the Roman Empire to Vichy France and the Eastern Bloc, where regimes depended on citizens denouncing one another. Its connotations are invariably negative, evoking betrayal and moral compromise rather than civic duty, which distinguishes it sharply from neutral terms like "reporting."

"Under the regime, delation became routine, as neighbours informed on one another to avoid suspicion themselves."
"The historian studied how systems of surveillance relied on widespread delation by ordinary citizens."
"Under Scots procedure, delation moved the case to a higher court for determination."
The plural is uncommon but attested, typically referring to multiple instances of denunciation.
"The archive contains hundreds of delations filed during the occupation."
In occupied France and behind the Iron Curtain, "delators" were so feared that the word itself became shorthand for a society turned against itself.

Etymology of delation
Delation comes from Latin delatio, meaning "a carrying down, bringing before a court, or accusation," formed on deferre (de- "down" + ferre "to carry"), the same verb that gives English relate, translate, and dilate. It was adopted into English legal vocabulary in the early seventeenth century, chiefly through Roman-law scholarship describing the delatores, the paid informers who flourished under the Roman Empire. A parallel sense survives in Scots law, where it refers to transferring a case between jurisdictions.
How delation is actually used
A formal, literary word, largely restricted to historical, legal, and scholarly writing about informer cultures — totalitarian states, the Inquisition, Vichy France. Its connotations are strongly negative, implying betrayal and secret denunciation rather than legitimate reporting.
