The word is coined by Baldassare Castiglione in The Book of The Courtier (written 1508-1528) where he says

In this translation sprezzatura is read as "nonchalance". I’m not sure that’s how the word is now being used or even if that translation is accurate. I suspect that sprezzatura is one of those words like gestalt or zeitgeist that have no immediate equivalent in English, representing as they do a concept or idea as much as a single, knowable entity.
