Or a sea change...

Now on the matter of unique, get a grip, chaps. I should think that a majority of people (only guessing) who use unique in everyday parlance add a modifier. What they are doing is using the word in a different sense to the one you wish to cling to. They are not saying the only one of a kind. They are saying special, different, outstanding, all words that can take a modifier. The word is undergoing a dichotomy of meaning. That's how language evolves and we should cheer it on. So far it's only a nice distinction (see what I did there...?), but you won't stop it growing.
