This volume is a selection of twenty peer-reviewed articles first presented at the 41st annual Linguistic Symposium on Romance Languages (LSRL), held at the University of Ottawa in 2011. They are thematically linked by a broad notion of variation across languages, dialects, speakers, time, linguistic contexts, and communicative situations. Furthermore, the articles address common theoretical and empirical issues from different formal, experimental, or corpus-based perspectives. The languages analyzed belong to the main members of the Romance family, Spanish, Portuguese, Catalan, French, Ladin, Italian, Sardinian, and Romanian, and a variety of topics across a wide spectrum of linguistic subfields, from phonetics to semantics, as well as historical linguistics, bilingualism and second-language learning, is covered.
