Paraleipsis \Par`a*leip"sis\, n. [NL., fr. Gr. ?, fr. ? to leave
   on one side, to omit; para` beside + ? to leave.] (Rhet.)
   A pretended or apparent omission; a figure by which a speaker
   artfully pretends to pass by what he really mentions; as, for
   example, if an orator should say, "I do not speak of my
   adversary's scandalous venality and rapacity, his brutal
   conduct, his treachery and malice." [Written also
   paralepsis, paralepsy, paralipsis.]
   [1913 Webster]
