East Midlands English is a traditional dialect with modern local and social variations spoken in those parts of the Midlands loosely lying east of Watling Street separating it from West Midlands English, north of a variable isogloss of the variant of Southern English of Oxfordshire and East Anglian English of Cambridgeshire and south of another that separates it from Yorkshire dialect. This covers approximately the East Midlands of England (Derbyshire, Leicestershire, Lincolnshire, Nottinghamshire, Rutland and Northamptonshire).
