Mint as a decriptive is very well placed in the lexicon of the English language in my opinion. Its use has wandered off topic somewhat, rather like this topic ironically, yet it still encapsulates a whole sentence of conceptual description in 4 letters. That is powerful stuff.
Words are power and short words that convey strong concepts are the most powerful of all. The English language is a very vibrant and regenerating language. That the word mint still has this meaning when in context shows its strength and staying power. It will be around long after we get off the dementia train thats for sure.
One of the newest and conceptually interesting words to enter the english language recently has to be Dench, in my opinion. As in:
That is a well Judy car mate. Proper Dench.
or
Thats a Dench paint job you have there mate.
English eats, subsumes and flat out destroys all smaller languages that get in its way and will be one of the three languages we take into space. In 2000 years time I honestly hope there are second hand atmospheric speeder pod adverts with the word 'Mint' in the title.
