Jennifer Smith is Professor of Sociolinguistics at the University of Glasgow. Her research is in language variation and change, concentrating on the origins and development of dialect from infancy onwards. Mercedes Durham is a Senior Lecturer in Sociolinguistics at Cardiff University. Her research looks at how linguistic variation and language change are acquired, transmitted and viewed by individual speakers and across successive generations.
