The power of language to create social, political, and racial identity was of central concern to Americans in the nineteenth century, and the implications of language in this regard are strikingly revealed in the writings of Howells, the most influential critic and editor of his age.In this first full-scale treatment of Howells as a writer about language, Elsa Nettels offers a historicNational characteristics, American, in literatureSpeech and social statusUnited StatesLanguage and languages in literatureEnglish languageUnited StatesSocial classes in literatureAmericanisms in literatureRace in literatureNational characteristics, American, in literature.Speech and social statusLanguage and languages in literature.English languageSocial classes in literature.Americanisms in literature.Race in literature.818/.409Nettels Elsa1504891MiAaPQMiAaPQMiAaPQBOOK9910787467903321Language, race, and social class in Howells's America3734177UNINA
