The phenomena discussed by the authors range from synthetic compounding in English to agreement alternations in Arabic and complementizer agreement in dialects of Dutch. Their exposition combines insights from lexicalism and distributed morphology, and is expressed in terms accessible to scholars and advanced students. The features of this book are: unique exploration of interfaces of morphology with syntax and phonology; wide empirical scope with many new observations; theoretically innovative and important; and accessible to students with chapters designed for use in teaching.
