How did the American accent form?
Some people say that this is how all Anglophone countries talked back in 1776, and since splitting it was actually the British and Aussies who changed dialects.
I also here from people that American accents have a German flavor to them.
Well both British and American accents have changed since 1776 because language isn't static
the current one is hollywood brainwashing the california accent if you will
this, as shocking as that might be for some to discover
That is false.
Roanoke Islanders apparently have the dialect closest to early Anglo-American settlers on the continent. Anthropologists study them quite a bit for that reason because the dialect is kinda a mystery.
The only unaccented American voice is that of the Bostonian. It may just be how the British sounded like in 1776. I dont know.
How do any accents form? British people came to America and the distance developed their own dialect continuum.
The reason American accents aren't as divergent is because America is younger. Australian accents are even less divergent than Americans because they are younger than us.
The Boston accent, or at least what's known as the "Yankee Twang", emerged primarily through East Anglian dialects
I don't remember the source, but I once heard that the modern Philadelphia accent is more or less what came over from England. The other accents formed due to a mixture of immigrants, each with their own accent. I buy it, the Minnesota accent has a similar ring/tone to Norwegian.
When people moved West, they mixed together and so did their accents. The result was a West Coast accent that is a mixture of other American accents. But, because accents evolve, you can now distinguish between different cities or parts of cities on the West Coast as well. The Hollywood accent is found in the part of LA that is West of Downtown all the way to Santa Monica, South of the Hollywood hills, and North of the 10 Freeway.
Australian accent sounds like American and British combined
