Since I posted the link to Nathan Bransford's blog on errors in usage of the English language, I've been noticing and writing down egregious examples of such erroneous usage in printed work:
Shutter used in place of shudder, dribble used in place of drivel, diary used instead of dairy, viscous instead of vicious, hurtling instead of hurling, pummeling instead of plummeting ("pummeling through the sky"!), and whicker (an animal sound) used where the word should have been wicker (a type of furniture).
Some of these examples should never have made it past a competent editor.
Then there was the email I received a week ago from an actual e-book vendor who should have known better: "The Oscar's aired this week and we have alot of the Academy award winner's movie tie-in eBooks featured at . . ."
Gahhhhh!
