Etymology

Origin of aplomb

First recorded in 1820–30; from French à plomb “according to the plummet” (straight up and down, vertical position); cf. plumb ( def. )


Explanation

Aplomb is the ultimate test for cool: grace under pressure. Use aplomb to show great restraint under even the most trying circumstances. In retail, it's always a good idea to handle the angry customers with aplomb. Angry at the long lines at the grocery store? Irritated because the driver ahead cut you off? Take a deep breath, and approach life's messes with aplomb. When you think of aplomb, think cool, calm and collected. Not frazzled, furious, and fiery. Aplomb comes from the French word meaning "perpendicularity," from the phrase à plomb for "poised upright, balanced."
