Etymology

Origin of eyebrow

First recorded in 1575–85; eye + brow

Explanation

Your eyebrows are the curved areas of hair on your face above each of your eyes. The purpose of eyebrows is to keep dust and sweat from getting in your eyes. Eyebrows help protect your eyes, but they're also an expressive part of your face, often giving away your mood instantly — especially ones like surprise or anger. While just about everyone can raise and lower both eyebrows together, only some of us can move them independently of each other. The size and shape of eyebrows varies widely from person to person, and many people pluck individual hairs from their eyebrows to shape and thin them.
