OK. I think I finally have an example:
ALL the residents of Canada, the USA, England, New Zealand and Australia, SO FAR AS I KNOW, call that pouched marsupial a KANGAROO, because that is what the Aboriginies of Australia call it, in their own language. None of those English-speakers made up a new name for that animal; they accepted the existing one.
And today, so far as I know (and I have been in a lot of foreign countries, including Texas) , if you utter the word “KANGAROO” in any country on Earth, the majority of that country’s population will know the kind of animal to which you are referring.
It is a word, like “OKAY,” that is universally recognized, all over the globe.
So what I am saying is that, if everyone on Earth seems to understand “OKAY” and even “PARDON,” it isn’t all that much of a stretch, to think that everyone on Earth could use the same word to describe Japan, and that would be the only word THEY use, which is “NIPPON”.
Another word everyone on Earth knows and uses, is “BUSH”.
You say that word anywhere on this planet, and anyone to whom you utter it, KNOWS you’re referring to the head Doofus in Washington, DC.
