This volume brings together selected papers from the 48th annual Linguistics Symposium on Romance Languages, held at York University in Toronto, Canada, in April 2018. It presents original research on a wide variety of Romance languages both past (Latin, Old Catalan, Old Iberian Romance, Old Spanish, Old Portuguese, and West-Iberian Medieval Latin) and present (Brazilian Portuguese, Catalan, French, Picard, Portuguese, Romanian, and Spanish) along with a number of contemporary dialects, including Basque Country Spanish, Dominican Spanish, Maine French, Neapolitan, and Picardie French. Divided into four sections — Interfaces, Bridging issues at the CP-TP-vP levels, Bridging issues at the PP-DP levels, and Bridging issues in linguistics — the volume gives researchers and advanced students access to contemporary issues and novel ideas bridging across various areas of Romance linguistics (e.g., morphology, syntax, semantics, phonology, sociolinguistics, first and second language acquisition).
