Etymologyedit

The interjection and noun are derived from made-up pseudo-Latin magical incantations used by conjurers (formerly called “jugglers”) such as “hocus pocus, tontus talontus, vade celeriter jubeo” (with a particular 17th-century conjurer adopting Hocus Pocus as his name)[1] and “hax pax max Deus adimax”.[2][3] The suggestion that the term is a corruption of words from the Roman Catholic liturgy of the Eucharist, “hoc est enim corpus meum” (“this is my [i.e., Jesus’s] body”), was made in a sermon by the Archbishop of Canterbury, John Tillotson (1630–1694),[4] but is not generally accepted.[3]

The verb is derived from the noun.[5]
