This Language, A River is an introduction to the history of English that recognizes multiple varieties of the language in both current and historical contexts. The book aims to enable students to both grasp traditional histories of English, and to extend and complicate those histories. Exercises throughout provide opportunities for puzzling out concepts, committing terms and data to memory, and applying ideas. A comprehensive glossary and up-to-date bibliographies help to guide further study. This accompanying workbook includes exercises keyed to each chapter of the textbook. Exercises are graded into beginning, intermediate and advanced groupings, which will aid in making the textbook appropriate for different levels of students.
