Dickens was famously drawn to the vernacular language of London's streets, but this book is the first to call attention to how he employed phrases that embody actions, ideas, and social relations for specific narrative and thematic purposes. Focusing on the mid- to late career novels Dombey and Son, David Copperfield, Bleak House, Great Expectations, and Our Mutual Friend, Capuano demonstrates how Dickens came to relish using common idioms in uncommon ways and the possibilities they opened up for artistic expression. Dickens's Idiomatic Imagination establishes a unique framework within the social history of language alteration in nineteenth-century Britain for rethinking Dickens's literary trajectory and its impact on the vocabularies of generations of novelists, critics, and speakers of English.
