Do you cringe when a talking head pronounces "niche" as NITCH? Do you get bent out of shape when your teenager begins a sentence with "and"? Do you think British spellings are more "civilised" than the American versions? If you answered yes to any of those questions, you're myth-informed.

In Origins of the Specious, word mavens Patricia T. O'Conner and Stewart Kellerman reveal why some of grammar's best-known "rules" aren't-and never were-rules at all. This playfully witty, rigorously researched book sets the record straight about bogus word origins, politically correct fictions, phony français, fake acronyms, and more. Here are some shockers: "They" was once commonly used for both singular and plural, much the way "you" is today. And an eighteenth-century female grammarian, of all people, is largely responsible for the all-purpose "he." From the Queen's English to street slang, this eye-opening romp will be the toast of grammarphiles and the salvation of grammarphobes. Take our word for it.
