The current volume contains a selection from papers presented at the 45th meeting of the Linguistic Symposium on Romance Languages (LSRL 45), which took place from May 6 to 9, 2015 at the University of Campinas, Brazil. A volume of selected papers, such as this one, will ultimately be successful contingent upon the success of the event itself, which proved a strong commitment to theoretical and empirical rigor to the studies in Romance linguistics. All the chapters in this volume are high-quality papers on the state-of-the-art in linguistic research into Romance languages. The studies offer a variety of topics on the syntax, phonology, semantics-pragmatics, L2 acquisition and contact situations of Romance languages (Peninsular and American Spanish; European, Brazilian and African Portuguese; French; Italian), Romance dialects (Borgomanerese) and Romance-based creoles (Palenquero).
