Am I the only one who thinks it weird that Washington has a modern American accent (and a slightly southern one, at that)?
American colonists in 1770s were English - half were born in England.
I mean, I understand why they went the way they did, I just think its funny.
I realize I am very late getting in on this one, but...
This is one of the more annoying aspects of watching historical pieces, for those who are more familiar with the history of the English language, and linguistics in general. People assume that since Britain is the parent country, obviously the people who came directly from there, in the early days, sounded what we think of as British. Not true. In fact, the British people of that era would have sounded closer to what we think of as "American". Many of the British dialects that we have today didn't even exist prior to the 19th century. In addition to that, if you have one group of people who branch out from the main group, as American settlers did from the British, and then from each other, it is actually the manner of the English (in this case) spoken by the splinter group that tends to change the least. This is because spoken language is under the constant influence of various factors, and thus in a constant state of flux, while a splinter group that manages to hang onto their language is usually under far less influence, because they are generally isolated by various factors.
So, indeed, the Americans of that era would have sounded perfectly "American" to us, while the British... also would have sounded pretty "American," for the most part. British pronounciations then continued to change in Britain, as people moved around alot... and some other things happens as well, that are both unusual in the broad history of languages, and which I won't get into, but if you are interested, look up the "Received Pronunciation", and these things gave British English its particular sounds. While, in the United States and Canada, there were changes, and in some dialect regions, major shifts, but for the most part, English here as maintained more of its original character from the people who first came here. For an example of media that actually gets it right, watch the John Adams miniseries.
