Re: US original Spelling Myth
Normandy wasn't quite the same as other "French" regions
Just like 'English' isn't really a monolithic language - every Saxon/Angle/Jute region had it's own dialect and (to a large extent) those differences were retained into modern English. And lets not forget the huge Norse/Celtic influences either - northern English retains a lot of Norse (and in places like Cumbria, Celtic influences).
In short, English is the illigetimate offspring of many mothers and farhers. Mixed in a decidedly promiscuous way.. Mind you, it still grinds my gears when I see the total lack of grammar and mistakes in vocabulary in (particularly) self-published books.
