This book aims to provide a thorough and wide-ranging introduction to approaches to morphology within linguistic theory over the last twenty years. This comprehensive survey concentrates not only on the generative linguistic mainstream, discussing the lexicalist morphology initiated by Chomsky and the syntactically orientated approaches that have developed in the '80s, but on approaches that are less fashionable or relatively unknown to English-speaking linguists. It highlights neglected European theoretical developments, focusing on German-speaking as well as English-speaking countries. The author's critical approach analyses as well as identifies the issues to give an up-to-date and intelligible overview of current morphology.
