This volume assembles a significant number of selected papers that were presented at the 21st edition of Going Romance, which was organized by the Chair of Romance Linguistics of the University of Amsterdam in December 2007. The range of languages (both standard and non-standard varieties) analyzed in this volume is quite significant: Catalan, French, Italian, European and Brazilian Portuguese, Romanian and Spanish. The volume is quite representative of the spread of the variety of research carried out nowadays on Romance languages within theoretical linguistics and shows the vitality of this research.
