I’m taking another run at yesterday’s Q&A. I was apparently wrong about being wrong. I’d been using em dashes correctly all along, if only by accident, since we loosely follow AP style on WhatIs.com. All right … here it goes again. (Pls. note correct AP-style ellipsis. YES — I learned something else already today!)
Answer: It depends on your style.
AP style is to add spaces around the em dash; Chicago style is without spaces. What happened yesterday? I found a source that seemed authoritative and went with it. But that source was following the Chicago Manual of Style. We’re (mostly) Team AP.
See AP vs. Chicago on em dashes and ellipses. Now there’s a blog for a fake grammarian to bookmark.
