An invaluable reference tool for students and researchers in theoretical linguistics, The Wiley Blackwell Companion to Morphology brings together over 80 empirical case studies investigating the development and historiography of the field of morphology. These case studies present a set of data from a well-delimited empirical area, whose analysis has played an important role in the theoretical debates, providing the data behind well-established empirical generalisations and observations. It also draws out the theoretical relevance of these empirical data sets, but in terms that do not depend too much on the concepts and ideas of one specific theory only. Encyclopedic in length, this Companion covers a large number of subdomains of morphology, including derivational processes, inflectional processes and types of morphology, in addition to analyzing the interaction of morphology with syntax and phonology. Under the editorship of four esteemed researchers in the field, it brings together cutting-edge contributions from a global group of linguists. The Wiley Blackwell Companion to Morphology features an accessible alphabetical structure across 5 print volumes, as well as being available online. Setting the standard for the field, this is an essential and unparalleled collection of morphological research.
