Forms

mystifier[1]

Etymology

It is a jocular formation from French μύστης (mústēs, “one initiated into the mysteries”) + -ifier + lang1=grc.[2][3][4][5] Wiktionary instead derives it from the Latin form mysta.[1] The word arose in the playful societies of the mid-18th century, where mock initiations were staged at the expense of credulous people; the best known victim was the writer Poinsinet, who was even made to believe that the King of Prussia wanted him to tutor the crown prince.[5][3][6] Littré thought its makers may have remembered the 16th-century words mistigouri and mystigorfier, of unknown formation, and rejected Latin maestificō (“to sadden”) as the source.[6] It is related to mystère and mystique.[3]

Earliest recorded meaning

It is first recorded as a past participle in 1760, in Favart's memoirs and letters, and as an infinitive in 1764 in Grimm's Correspondance littéraire, meaning to fool a naive person for amusement.[2][4]

Semantic evolution

The first sense was to deceive someone by abusing his credulity in order to laugh at him.[3][2] From 1831 (Balzac) it was also used of misleading a person or a whole public by distorting or embellishing reality, and in current use it mostly means to deceive collectively on an intellectual or moral level.[3][2] The verb soon gave mystification (1768) and mystificateur (1770);[5][3] the opposite démystifier was coined by Sartre in 1948.[3] English mystify (1798) was taken from the French verb.[7]
