ELI5: How did the American Southern accent develop?
gpt
It's more the other way around, and relates to the question "When did American English break from British English?". At first American and British English were the same, but then British English developed into what it is today. American English has not changed as much, and is actually closer to British English of 200 years ago. American Southern has been even slower to change (because of the relative isolation of the speakers), and is even closer to British English of that time!
