Or at least, that's how it appears these days. On the BBC, I heard an art expert discussing a valuable vase. He described it as "unique, one of only eight in existence." Er, excuse me? Or another discussion on the radio. Somebody was informing us that something was "relatively unique." So, we now have degrees of uniqueness? I resisted the temptation to fling my radio out of the window and went to lie down instead.
