The relationship between changes in (inflectional) morphology and the consequences of these changes in syntax has been a perennial issue in historical linguistics. The contributors to this volume address the issue of how to model the phenomena of syntactic and morphological change within recent frameworks, including the Minimalist Programme. Topics addressed include the way categories like aspect and mood interact over time with the valency of verbs; the nature of changes in verb placement; the changing division of labor between different types of argument marking--case, word order, clitics, agreement. The volume contains chapters by many of the leading scholars in the field. There is a substantial introduction which reviews the development of ideas in generative historical syntax over the last fifteen years, and assesses the distinctive properties of the generative position. The volume will appeal to those working in theoretical syntax, and also to specialists in the history of German, French and the Romance and Germanic languages more broadly.
