Dear Americans,
It has come to my attention that the English language was only loaned to you on a semi-permanent basis. I discovered, only recently, and thanks to Jeff Bezos's example, that when we gave you your language, we were only loaning said language for the period of our occupation of the colonies.
Sadly we now must inform you that all rights and derivations of the English language used by aforementioned "Americans' must now cease and desist. All unused U's and replaced Z's must be returned to their proper positions within 30 days.
We have consulted Sylvester Stallone (who we have on good authority is a master of American English) to invent a new language. This new language will be formally known as Adrienish and will include a six-letter alphabet.
We wish you the best of luck in this transition period.
Yours
Her Maj
Queen Elizabeth II
