The contributors to this volume, an international group of leading specialists, guide us through different aspects of the study of Amerindian languages and societies that lie at the heart of the extensive and multi-facetted work of Willem Adelaar, the forerunning specialist in Native American studies of Meso and South America, and Professor of Amerindian Studies at Leiden University. The contributors focus on three larger regions, the Andes, Amazonia, Meso-America and the Circum-Caribbean region, giving us a state of the art overview of current linguistic and archaeological research trends that illuminate the dynamicity and historicity of the Americas, in migratory movements, contact situations, grouping and re-grouping of identities and the linguistic results thereof. This book is a must-have for all scholars of the American continent.
