A linguist with attitude, R. L. Trask was a steadfast soldier in the never-ending War of Words, fighting the good fight for standard written English. Revered for its insight and legendary for its "cheek," Trask's Mind the Gaffe! is an indispensable guidebook for wordsmiths and language mavens of every stripe, providing safe passage through the ubiquitous minefields of improper usage.
