aplomb

Picture a mason in sixteenth-century France holding a string with a lump of lead dangling at the end: gravity draws a perfectly honest vertical line. That lump was Latin plumbum, and its name survives in French à plomb, “on the plumb,” which became aplomb. The leap from vertical accuracy to emotional steadiness is wonderfully physical: a person with aplomb does not wobble, tilt, or get knocked off balance. By 1828, English had adopted the word for self-assurance; Emerson later used the archetypal “man of aplomb” in 1875, imagining someone who could sit amid youthful panic and fire off his words “like a bullet.” Ballet keeps the older image alive, using aplomb for unwavering stability in a vertical pose—so confidence, in this word, is essentially good posture with a lead weight underneath.
