Apophasis (/əˈpɒfəsɪs/; Greek: ἀπόφασις from ἀπόφημι apophemi,[1] "to say no") is a rhetorical device wherein the speaker or writer brings up a subject by either denying it, or denying that it should be brought up. Accordingly, it can be seen as a rhetorical relative of irony.
The device is also called paralipsis (παράλειψις) – also spelled paraleipsis or paralepsis – or occupatio, and known also as praeteritio, preterition, or parasiopesis (παρασιώπησις).
As a rhetorical device, apophasis can serve a number of purposes.
It can be employed to raise an ad hominem or otherwise controversial attack while disclaiming responsibility for it, as in, "I refuse to discuss the rumor that my opponent is a drunk." This can make it a favored tactic in politics.
