Sprezzatura
Sprezzatura ([sprettsaˈtuːra]) is an Italian word that refers to a kind of effortless grace, the art of making something difficult look easy, or maintaining a nonchalant demeanor while performing complex tasks. The term "sprezzatura" first appeared in Baldassare Castiglione's 1528 The Book of the Courtier, where it is defined by the author as "a certain nonchalance, so as to conceal all art and make whatever one does or says appear to be without effort and almost without any thought about it".
