I see a new combination of punctuation emerging, and demanding formal recognition. Consider an example in which the writer of an email, say, asks the recipient about possible meeting times. Some options for punctuation:
- Can we meet at any of these times: 12:30, 3:00, 4:30.
- Can we meet at any of these times? 12:30, 3:00, 4:30.
- Can we meet at any of these times: 12:30, 3:00, 4:30?
- Can we meet at any of these times?: 12:30, 3:00, 4:30.
Options 1 and 2 won’t work, as each one requires breaking grammatical form. In option 1, the writer abandons the requisite question mark; in option 2, no colon introduces the list of times, which thus becomes an incomplete sentence. Option 3 is more plausible, but the deferred question mark makes the opening interrogative clause “feel” wrong until one arrives at the end of the sentence.
Option 4, which I use often and hope will spread, accomplishes the goal of the sentence while keeping both question mark and colon in close proximity to the clauses to which they’re meant to apply.
I propose combining the two characters, ? and :, and naming the new mark the “interrolimb.”
The word follows the pattern established by the interrobang (a single character that can be used in place of !? or ?!), with a nod to the Greek roots of the word “colon”—which meant “limb” and so was also used in rhetoric to refer to clauses within sentences (just as we sometimes use “limb” to do).
As a first stab—and I’m no typographer—what do you think of these, set in Times?:
