Elizabeth Anscombe coined the term scare quotes as it refers to punctuation marks in 1956, in an essay entitled "Aristotle and the Sea Battle", published in Mind.[7] The use of a graphic symbol on an expression to indicate irony or dubiousness goes back much further: Authors of ancient Greece used a mark called a diple periestigmene for that purpose.[8] Beginning in the 1990s, the use of scare quotes suddenly became very widespread.[9][10][11] Postmodernist authors in particular have theorized about bracketing punctuation, including scare quotes, and have found reasons for their frequent use in their writings.[6][12]
