This volume contains a selection of twenty-four peer-reviewed papers from the 39th annual Linguistic Symposium on Romance Languages (LSRL) held at the University of Arizona in 2009. Contributions cover a wide variety of topics in the areas of phonology, phonetics, syntax, morphology, and diachronic Romance linguistics, with an emphasis on language variation and change. Among the languages and varieties of Romance analyzed are Spanish, French, Italian, Portuguese, Romanian, Catalan, Old French, Old Occitan, and Hispano-Romance. The research in this volume points to a cohesiveness in Romance linguistics that lies in the integration of up-to-date linguistic research with a comparative tradition and the in-depth study of a language family.
