This is the first text book to offer a comprehensive approach to Old Frisian. Part One begins with a succinct survey of the history of the Frisians during the Middle Ages, their society and literary culture. Next follow chapters on the phonology, morphology, word formation and syntax of Old Frisian. This part is concluded by a chapter on the Old Frisian dialects and one on problems regarding the periodization of Frisian and the close relationship between (Old) Frisian and (Old) English. Part Two consists of a reader with a representative selection of twenty-one texts with explanatory notes and a full glossary. A bibliography and a select index complete the book.
