Book excerpt: Drawing on detailed case studies across a range of languages, including English, German, Dutch, Italian, Portuguese, Polish, Czech, Russian, Lithuanian and Greek, this book examines the different factors that determine the outcome of the interaction between borrowing and word formation. Historically, borrowing has largely been studied from etymological and lexicographical perspectives and word formation has been included in morphology. However, this book focuses on their mutual influence and interaction. Bringing together a range of contributors, each chapter illustrates how borrowing and word formation are in competition as alternative naming processes, while also showing how they can influence each other. The case studies are framed by an introduction that describes the general background and a conclusion that summarises the main findings.
