Apophasis
Apophasis 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. Also called paralipsis (παράλειψις) – also spelled paraleipsis or paralepsis – or occupatio, and known also as praeteritio, preterition, antiphrasis (ἀντίφρασις), or parasiopesis (παρασιώπησις), apophasis is usually employed to make a subversive ad hominem attack, which makes it a frequently used tactic in political speeches to make an attack on one's opponent. Using apophasis in this way is often considered to be bad form.
