This volume brings together two particularly dynamic areas of contemporary research on the French language. The chapters showcase the most innovative current scholarship in historical linguistics, sociolinguistics, and in the burgeoning field of historical sociolinguistics which lies at their intersection. The research across the volume is strongly data-centred, drawing on a wide range of both well-established and more novel theoretical and methodological approaches in order to open up new perspectives on the study of the French language in the twenty-first century. Although it is written in English, the work presented here is underpinned by a range of different approaches from across the Francophone and Anglophone worlds. Particular emphasis is placed on combining quantitative and qualitative approaches, on diversifying tools, methods, and objects of inquiry, and on adopting comparative and multilingual perspectives where these shed new light on important questions relating to French. In these ways, Historical and Sociolinguistic Approaches to French highlights some of the most exciting new directions for linguistic research on the French language.
