The interrobang (“interabang”, with only one “r”) is variously written
- as a question mark superimposed over an exclamation mark ,
- as a question mark followed by an exclamation mark (?!), or
- the other way around (!?).
It was born in the 1960’s, but because most keyboards do not allow the typeover to combine the two marks, it did not gain wide usage.
The current AP Stylebook does not mention the interrobang.
The 17th edition of the Chicago Manual of Style mentions the interrobang only with the comment that they are making a list and considering it for the next edition. Its absence in the CMOS indicates that it is not appropriate (yet) for formal writing.
- “Can’t you see the fire?! It’s coming right at us!”
- “Will we get out in time?! Can’t you get the car started?!”
- “Did you ever see a cat wearing sunglasses!?”
Which comes first, the exclamation mark or the question mark depends upon the intent of the exclamation.
