I Always Look Up the Word "E-gre-gious"

Rather than being a cute book about words (c.f. Richard Lederer), this book is as elitist and erudite as its title suggests. It reaches beyond its analogues with exercises, for example: given English synonyms in Latin and Greek, what is the English synonym with an Anglo-Saxon root? If you're interested in the English language, grab this book if you can find it. (It defines zeugma, after all - how can you live without a book that does that?)
