I do enjoy the topic though, as an English teacher and linguist.

Other interesting examples are get,got,gotten of American and Australian English. British English uses get,got,got. But hundreds of years ago gotten was used for the past participle- but the British abandoned it and Americans and Australians retained the old English form.

I won't go into Soccer- but it has a similar though more recent history.

The most interesting one, though, is the TU sound. Americans say TOOna, Brits and Aussies say Choona.

But this CH sound for TU is not native to English at all, and only crept in in the last 200 years from French. Even though the Normans spoke French and the Kings and aristocrats spoke French in England for hundreds of years, it wasn't until centuries later that this TU sound as CH entered the language, long after America was foundered. Here, though it sounds weird to my ears, the Americans have it more correctly.
