Interjections are suitable for online writing, as I say, because of the way online writing mimics speech. But newspaper and magazine writers who spell out interjections and other vocalisms run the risk of coming off as cute—as in yucky ew rather than adorable awwa. Most egregiously abused are what linguists call "discourse markers"—short sounds (it seems a stretch to call them "words") that speakers use to register hesitation, agreement, encouragement, ambivalence, and other responses. Uh, er, and um, in particular, have been flagrantly overused by feature writers and columnists to signal an impending attempt at irony or humor; the maneuver is now well beyond cliché, somewhere in the neighborhood of desperation. A LexisNexis search of major English-language newspapers for um yields 132 hits in just the last week, including a striking number in various newspapers' coverage of the Grammy Awards:
The Toronto Sun's preview: "Watch for Justin Timberlake pairing up with someone in a duet (which often can be quite, um, revealing)."
The Chicago Sun-Times, looking back on a winner of yore: "the Starland Vocal Band, who gave us the, um, unforgettable single, 'Afternoon Delight.' "
The Oregonian, referring to Christina Aguilera: "the girl who was once known as much for her, um, dirrtyness showed she cleans up real nice, too."
St. Petersburg Times: "Shakira, Wyclef, and, um, Shakira's abs teamed up for the dance smash Hips Don't Lie."
My reaction to all that?
