Testing linguistic theory and variation to their limits: The case of Romance

Through a number of illuminating cases studies which draw in large part on the largely under-utilized data of Romance dialectal varieties, the present article sets out to highlight the importance that Romance data, especially those of non-standard varietites, can play in testing and enriching currents theories of syntax. In particular, we shall show that dialectal varieties, although frequently overlooked in the past, offer an immensely fertile and still relatively unexplored experimental territory in which to profitably investigate new ideas about language structure, change and variation. At the same time, we champion the mutual benefits for theoretical linguists and Romanists of adopting a more integrated and reciprocally-informed approach in their respective treatments of linguistic evidence, highlighting how a familiarity with the key tools and ideas established in both fields has the potential to enrich linguistic and empirical analyses considerably.
