Mind the Gaffe: The Penguin Guide to Common Errors in English by R. L. Trask

Fortunately, all those who have ever feared being shown up by using one of the twenty worst words and phrases to be avoided at all costs, or confusing the complex with the complicated, can now relax and even enjoy a trouble-shooting guide to good writing. Trask's wonderfully readable and authoritative book adjudicates on hundreds of contentious issues from politically correct language to whether to write 'napkin' or 'serviette'.
