East Anglian English is a dialect of English spoken in East Anglia, primarily in or before the mid-20th century. East Anglian English has had a very considerable input into modern Estuary English, which has largely replaced it. However, it has received little attention from the media and is not easily recognised by people from other parts of the United Kingdom. East Anglia is not easily defined and its boundaries are not uniformly agreed upon. The Fens were traditionally an uninhabited area that was difficult to cross, so there was little dialect contact between the two sides of the Fens.
