A state-of-the-art survey of complex words, this volume brings together a team of leading international morphologists to demonstrate the wealth and breadth of the study of word-formation.Encompassing methodological, empirical and theoretical approaches, each chapter presents the results of cutting-edge research into linguistic complexity, including lexico-semantic aspects of complex words, the structure of complex words, and corpus-based case studies.Drawing on examples from a wide range of languages, it covers both general aspects of word-formation, and aspects specific to particular languages, such as English, French, Greek, Basque, Spanish, German and Slovak.Theoretical considerations are supported by a number of in-depth case studies focusing on the role of affixes, as well as word-formation processes such as compounding, affixation and conversion.Attention is also devoted to typological issues in word-formation. The book will be an invaluable resource for academic researchers and graduate students interested in morphology, linguistic typology and corpus linguistics.
