Yorkshire covers a large area – around 2.9 million acres! A wide variety of accents and dialects are spoken across and within its individual counties of North, West, East and South Yorkshire.  North Yorkshire is one of the largest counties in England and the language in and around the North York Moors is quite different from what many people would recognise as ‘Yorkshire’. Here we explore the fascinating story behind the development of this unique dialect, and the work of the fieldworkers from the Survey of English Dialects to record it.
