And that's exactly the point. They would never do it because there isn't a word to describe it, as you've just said, which would prove that were the word removed then the concept wouldn't exist. Imagine this (oh I love hypothetical situations): Millions of years ago there were Fruvians. They were fruvous every morning, until someone removed the word from their vocabulary. Then in the present day, it's reintroduced, and people once again feel fruvous. But over a million years, fruvousness failed to exist
I know it's awfully written and a stupid arguement... but my point is hidden in there. Somewhere.
