I was just wondering if anyone knew why Americans (I think i'm including Canadians here too) spell some words differently to the rest of us English speakers? When did it originate and what made them pick only certain words?<br />Now i'm basing this on the assumption that the English spelling of words is the original way and that it was deliberately changed somewhere along the line. Here in Australia where I am we tend to side with the English version but the odd American version can be interchanged. There are many words that differ and maybe some Americans may not even be aware of it, I don't know.<br />Examples are litre, aluminium, colour, programme, gauge to name a few.
