The Cambridge handbook of morphology The Cambridge Handbook of Morphology describes the diversity of morphological phenomena in the worlds languages surveying the methodologies by which these phenomena are investigated and the theoretical interpretations that have been proposed to explain them. The Handbook provides morphologists with a comprehensive account of the interlocking issues and hypotheses that drive research in morphology; for linguists generally it presents current thought on the interface of morphology with other grammatical components and on the significance of morphology for understanding language change and the psychology of language; for students of linguistics it is a guide to the present day landscape of morphological science and to the advances that have brought it to its current state; and for readers in other fields (psychology philosophy computer science and others) it reveals just how much we know about systematic relations of form to content in a languages words and how much we have yet to learn.
