No one has an accent. It’s only other people who talk different.
But back in the nineteenth century, as railways brought greater mobility and the beginnings of standardisation of the language used country wide there were some folk who realised that the ways of speaking area by area needed recording. In 1755 Johnson published his Dictionary of the English Language.
From then until now, others have taken up the challenge of recording. Here are some of them.
John Trotter Brockett – 1847 A Glossary Of North Country Words
Joseph Wright – 1898 The English Dialect Dictionary – being the complete vocabulary of all dialect words still in use, or known to have been in use during the last two hundred years; founded on the publications of the English Dialect Society and on a large amount of material never before printed.”
Richard Oliver Heslop – 1892 A Glossary of Words Used in the County of Northumberland
Heslop also published under the name of Harry Haldane, and his position as President of the Newcastle Literary and Philosophical Society was instrumental in his work being highly regarded as an important text defining the Northumbrian Language. More information is on this page.
