The book is a tribute to the legacy of Michael Clyne, researcher and advocate of multilingualism in Australia and abroad over a lifetime, and source of lasting inspiration for his many colleagues around the world, including those who contributed to this book with case studies across Australia, Europe and Asia. Australia has been a continent of immigration for many people and newborn generations with a wide spectrum of European roots. In its turn, this book will function as a rich source of learning and inspiration for many interested researchers and students who have witnessed and experienced the passage of Europe from a continent of emigration to immigration.
