Word History: The English word supercilious ultimately derives from the Latin word supercilium, "eyebrow." Supercilium came to mean "the eyebrow as used in frowning and expressing sternness, gravity, or haughtiness." From there it developed the senses "stern looks, severity, haughty demeanor, pride." The derived Latin adjective superciliōsus meant "full of stern or disapproving looks, censorious, haughty, disdainful," as it has since it entered English as supercilious in the 1500s. The super- in the Latin word supercilium means "above," and cilium was the Latin word for "eyelid." In many of the Romance languages, this word developed into the word for "eyelash." This development is probably reflected in the scientific use in English of the word cilium, whose plural is cilia. Cilia are the minute hairlike appendages of cells or unicellular organisms that move in unison in order to bring about the movement of the cell or of the surrounding medium.
