The interrobang (/ɪnˈtɛrəbæŋ/),[1] also known as the interabang[2] (often represented by any of ?!, !?, ?!? or !?!), is an unconventional punctuation mark used in various written languages and intended to combine the functions of the question mark, or interrogative point,[3] and the exclamation mark, or exclamation point, known in the jargon of printers and programmers as a "bang". The glyph is a ligature of these two marks[4] and was first proposed in 1962 by Martin K. Speckter.[5]
