This volume represents the first work published in English dealing with the historical grammar of Romanian from a modern theoretical perspective. It consists of a selection of papers focusing on the historical grammar of Romanian, bringing together diverse theoretical approaches in order to address a number of key morphological and syntactic issues in the history of the morphosyntactic development of Romanian. The majority of papers in this volume deal with topics in Romanian historical syntax, drawing on modern research methods and current linguistic theory, with a clear preference for parametric syntax. The most significant areas of grammar, namely the nominal domain and the verbal domain, are well represented in this volume.In the context of current research on the history of the Romance languages, this volume is auxiliary to recent works such as Maiden, Smith, and Ledgeway's Cambridge History of the Romance Languages (Cambridge University Press, 2011) and Ledgeway's From Latin to Romance. Morphosyntactic Typology and Change (Oxford University Press, 2012), which contain relatively few references to Romanian.The volume will be of interest to advanced graduate and postgraduate students in diachronic linguistics, theoretical linguistics, and Romance and Romanian linguistics, as well as researchers in the fields of historical and typological linguistics, morphosyntactic theory and the history of the Romance languages.
