The idea that any one group of people “created” the English language, or that the people currently living in England are the direct heirs of that group, is, in a word, hogwash.
The very concept of the English language is that it, like nearly all other languages, is in a constant state of evolution.
“Colour” is how you have spelt it. We have spelled it color.
Any whining about the origin of the language shows just how irrelevant the English realize themselves to have become.
Pretty soon, you’ll emulate the French, and open an Academy for the Preservation of the Integrity of the English Language.
And we all know just how relevant the French are…
