This book provides a very readable and up-to-date description of language variation in American English, covering regional, ethnic, and gender-based differences. The authors include situations ranging from historically isolated, rural dialects to developing, urban ethnic varieties as they consider the descriptive, theoretical, and applied ramifications of dialects in American society. The second edition of American English includes new chapters on social and ethnic dialects, including more comprehensive discussions of Latino, Native American, Cajun English, and other varieties, samples from a wider array of US regions, and a separate chapter on African American English. Updated chapters and exercises as well as features such as a phonetic symbols key, and a section on the notion of speech community, combine to make the new edition a valuable resource for students and specialists alike.
