Apophasis

Apophasis (; from Ancient Greekἀπόφασις (apóphasis), from ἀπόφημι (apóphemi)'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. A classic example of apophasis is "I'm not going to say that I told you so".

The device is also called paralipsis (παράλειψις) – also spelled paraleipsis or paralepsis – or occupatio or occultatio, and known also as praeteritio, preterition, or parasiopesis (παρασιώπησις).
