[sprettsaˈtuːra]: An Italian word coined by Baldassare Castiglione in The Book of the Courtier (1528)
"To practice in all things a certain Sprezzatura [nonchalance], so as to conceal all art and make whatever is done or said appear to be without effort and almost without any thought about it."
The Appearance of Effortless Mastery;
"Whether they have designed clothes, written poetry, composed operas, built public squares, painted for popes, hewn marble, or sailed the fathomless seas, many Italians of genius have placed a premium on achieving an appearance of effortless mastery, or sprezzatura, that is attained only by costly, concentrated effort and unremitting labor.
