Book excerpt: The annual Going Romance conference has developed into the major European discussion forum for theoretically relevant research on Romance languages where current ideas about language in general and about Romance languages in particular are tested. The twenty-third Going Romance conference was a very special one: for the first time it was not hosted by one of the Dutch universities, but was co-organized by the Radboud University Nijmegen and the Université de Nice-Sophia Antipolis and held in France at the Maison du Séminaire in Nice from 3–5 December 2009. The present volume contains a broad range of peer-reviewed articles dealing with syntax, phonology, morphology, semantics and acquisition of the Romance languages as well as selected papers from the special workshop dealing with linguistic change in relation to linguistic theory.
