The question mark is such a simple thing, so why bother even looking at it? It simply goes after a question, so what’s the issue? Why is this error so vital to our writing?
Roy Peter Clark author of The Glamour of Grammar says, “The question mark, used well, may be the most profoundly human form of punctuation. Unlike the other marks, the question mark—except perhaps when used in a rhetorical question—imagines the Other. It envisions communication not as assertive by as interactive, even conversational. The question is the engine of debates and interrogations, of mysteries solved and secrets to be revealed, of conversations between student and teacher, of anticipation and explanation. There are Socratic questions, of course, where the interrogator already knows the answer. But more powerful is the open-ended question, the one that invites the other to act as the expert in telling his own experience” (Little, Brown, 2010).
