This volume contains a selection of nineteen peer-reviewed papers from the 40th annual Linguistic Symposium on Romance Languages (LSRL) held at the University of Washington in March 2010. In addition to overviews of Romance linguistics by the editor and by Jurgen Klausenburger in the keynote article, contributions cover a variety of linguistic theoretical topics and a range of Romance languages, including Old and Modern French, Italian, Romanian as well as several dialects of Spanish and Portuguese. A number of papers deal with the morphophonology of Peninsular Spanish languages, agreement anomalies, generic interpretation, and the syntax/semantics of determiners, particularly of Romanian. Both the topics and the languages discussed in this volume are tied together by a number of 'leitmotifs', and several articles present phenomena not previously considered. The volume makes significant contributions both to the documentation of Romance languages and to linguistic theory, and will be of interest to Romance and general linguistics scholars.
