Noreen Malone — who admits to being an em-dash abuser herself — makes an appeal for everyone to just leave the em-dash alone!
According to the Associated Press Stylebook — Slate‘s bible for all things punctuation- and grammar-related — there are two main prose uses— the abrupt change and the series within a phrase — for the em dash. The guide does not explicitly say that writers can use the dash in lieu of properly crafting sentences, or instead of a comma or a parenthetical or a colon — and yet in practical usage, we do. A lot — or so I have observed lately. America’s finest prose — in blogs, magazines, newspapers, or novels — is littered with so many dashes among the dots it’s as if the language is signaling distress in Morse code.
What’s the matter with an em dash or two, you ask? — or so I like to imagine. What’s not to like about a sentence that explores in full all the punctuational options — sometimes a dash, sometimes an ellipsis, sometimes a nice semicolon at just the right moment — in order to seem more complex and syntactically interesting, to reach its full potential? Doesn’t a dash — if done right — let the writer maintain an elegant, sinewy flow to her sentences?
Nope — or that’s my take, anyway. Now, I’m the first to admit — before you Google and shame me with a thousand examples in the comments — that I’m no saint when it comes to the em dash. I never met a sentence I didn’t want to make just a bit longer — and so the dash is my embarrassing best friend. When the New York Times‘ associate managing editor for standards — Philip B. Corbett, for the record — wrote a blog post scolding Times writers for overusing the dash (as many as five dashes snuck their way into a single 3.5-paragraph story on A1, to his horror), an old friend from my college newspaper emailed it to me. “Reminded me of our battles over long dashes,” he wrote — and, to tell the truth, I wasn’t on the anti-dash side back then. But as I’ve read and written more in the ensuing years, my reliance on the dash has come to feel like a pack-a-day cigarette habit — I know it makes me look and sound and feel terrible — and so I’m trying to quit.
Bloggers (some of us, anyway) tend to use the em-dash a bit too frequently, and that’s one of the downsides to being one-person shows — there’s no kindly editor to strike through the excess punctuation with a red pen.
