The diversity of English dialects in the United Kingdom is enormous.
It’s common for people from either side of a river, mountain, or even town to speak noticeably different ways, with particular features that immediately mark someone out as being from a specific area, to those who have an ear for it.
This is pretty normal in any large region that has been speaking a language continually for 1600 years. You will find the same thing in Germany, Norway, France, and countless other countries. Languages evolve over time, and physical distance between regions means that new features often spread slowly, leading to dialectal differences. Sometimes these differences are small, and only easily recognised by people from the relevant region. Other times there are very clear distinctions, with neighbouring dialects sounding almost like different languages to those unaccustomed to them.
Here I have tried to capture as much nuance as possible. I’ve spent the last few years pooling together every study, survey, map, and database I can find, and then subjecting my image to several rounds of peer feedback. The members of my Facebook group, “Ah yes, the British accent”, were also a huge help in trying to make these borders as accurate as possible. The end result is an image which is, to my knowledge, the most detailed map of British dialects ever made. But it is still very much unfinished, and it always will be.
