History and Etymology for mystify

borrowed from French mystifier "to hoodwink, dupe," from Greek mýstēs "person initiated (into a religious cult)" + French -ifier -ify — more at mystic entry 1

Note: French mystifier was used by 18th-century literati in the context of elaborate practical jokes in which some pseudo-magical procedure would be performed on the subject of the joke as a sort of mock initiation. Such a joke is described by the playwright Charles-Simon Favart (1710-92) in a letter of June 24, 1760, apparently the earliest known occurrence of the verb: one Poinsinet is persuaded that the application of a magic ointment has made him invisible and he then becomes the butt of various jests. According to Favart, Poinsinet was dubbed le mystifié (presumably, "one made an inititate") as a result of the jests, which he refers to collectively as la mystification. (See Mémoires et correspondances littéraires, dramatiques et anecdotiques de C.S. Favart, tome 1, Paris, 1808, p. 50-52.) The meaning of the English word has been influenced by mystery entry 1, mystical, etc.
