Everyone hates cliches, but no one does anything about them. In fact, at the end of the day, most of us would have to admit, with all due respect, that we are driven round the bend on a daily basis by friends and co-workers who can’t stop tossing out overused metaphors and meaningless catchphrases. So what to do? Run right out and pick yourself up a copy of “The Dimwit’s Dictionary,” a compendium of 5,000 of the worst abuses of the English language, as well as reasonable alternatives for the more overused and irritating entries, all authored by the man who wrote the book on tired expressions. The tome may be a work in progress, but it’s almost sure to be an overnight success with language geeks.
