I was thinking about the word “cool” today. Cool like Frank Sinatra, not like the climate in Boston. It used to be slang, but I think it’s long since crossed over into being just a regular word. And I’d speculate that the success of the word is because it fills a void in the English language, where no other single word I can think of really fits the bill.
“Cool” doesn’t just mean “good”, it’s more like a mix of “good”, “popular”, “nonchalant”, “stylish”, etc. We all understand this concept. If someone said “You know, that quality that James Bond and John Shaft have, like Michael Jordan or Sinatra” you’d probably know what they meant, but without being able to say “They’re cool” it’s not so easy to articulate. The closest I can come is to say “It’s like a casual excellence.”
So that got me wondering: What other universally understood ideas are there that really cry out for a word to describe them? And feel free to invent a word that fits the bill.
