interrobang

The nonstandard punctuation mark ⟨‽⟩ (a combination of ⟨?⟩ and ⟨!⟩), which may be used at the end of a sentence to express excitement or disbelief, or to indicate that it is a rhetorical question.

Has anyone seen an interrobang? It's a newly invented punctuation mark that looks like this: ‽ A question mark with an exclamation point superimposed, it's meant to convey that nuance of feeling—a mixture of query and surprise—that people have in mind when they say "Really?", also meaning "Really!", or "How about that‽" […] The cure for incredibility is not more punctuation, but more plain talk. We don't need symbols like the interrobang that merely express our perpetual disbelief. We need plain words to express plain truths.

The Interrobang is not a font – just a single character. Yet it is so powerful a symbol, and such a flawed and original concept, that it deserves a place alongside the most adventurous typographic innovations of the last century. It is an exclamation mark and a question mark combined, a ligature looping the curve of the interrogation with the downward force of the expletive (which compositors and printers have traditionally called a bang). When they meld, they need only one round point at their base.

A combination of a question mark and an exclamation mark; ⟨!?⟩ or ⟨?!⟩.

Interrobang — !?, ?!, or ‽ / What?! You’ve never heard of the interrobang!? Really? Well, now you have, so all is forgiven. An interrobang is […] used to end sentences where you really want both the exclamation point and the question mark. […] The word is used to describe both the two side by side (!? or ?!) or the combined symbol (‽).

For instance, Taylor (2002: 568–570) discusses the ‘incredulity response construction’ in English as an example of a CI, exemplified by expressions such as Him write a novel?! and Me worry?! The CI has the schematic form of [nom_(sbj) v_(inf) (np)?!]. When written, it is often punctuated with an interrobang (‽ or ?!).

To exclaim and question at the same time.

“I think I can help Carli, but I have to move fast. Federal agents are going to descend on this place like locusts in about twenty minutes, max, and they’ll detain everyone. It’ll be days, at least, before they’re done interrobanging around.”

"Qhoenix!?" interrobanged Lrig Lanoisnemid-Eno. "You can't do this!"
