This book offers full coverage of such common mistakes as commas splices, sentence fragments, words frequently confused, words frequently misspelled, mixed metaphors, and subject-verb agreement errors. In each case the problem is clearly explained, with examples illustrating both the nature of the trouble and how to put it right. This fifth edition includes coverage of CBE (Council of Biology Editors) as well as MLA, APA, and Chicago style; new sections on academic writing and on business writing; and a chapter for those whose native language is not English.
