Interest in morphology has undergone rapid growth over the past two decades and the area is now seen as crucially important, both in relation to other aspects of grammar and in relation to other disciplines.

Andrew Spencer is Professor of Linguistics at the University of Essex. He has published on the theory of morphophonology and on a variety of topics in morphology. He is currently working on argument structure alternations in Russian verb classes and their nominalizations. He is author of two textbooks, Morphological Theory and Phonology (both published by Blackwell Publishers).

Arnold M. Zwicky is Professor of Linguistics at Stanford University and Ohio State University. He has published in all the major linguistics journals, with contributions to the fields of phonology, morphology, syntax and, perhaps most notably, the interrelations between these domains. He is particularly well-known for his contributions to morphophonological theory, inflectional morphology, and the theory of clitics. His first essays on clitics twenty years ago stimulated a flurry of research from a variety of scholars in what continues to be an important and developing area. In addition, he has edited a variety of collections on specific themes, including most recently serial verbs and second position clitics (with A. Halpern).
