When you see the words par excellence, you know you're talking about something supreme, outstanding, and first rate.
As you might guess from the word excellence, par excellence is a term of praise for things that are great. It's a French term that's used like this: "Michael Jordan was a superstar par excellence." Masters of their fields such as Shakespeare and Mozart were artists par excellence. This is a term that refers to the superiority of someone or something. The Louvre in Paris is a museum par excellence. This phrase of emphasis packs the punch of a verbal exclamation point.
