Etymology: The letter's name goes back to the Greek "kappa," which was itself adapted from the Phoenician letter "kaph." Over the centuries the Greek name was shortened in Latin and then in English, where it became the single syllable used to spell out the letter. The given name has a more storied past. In medieval Arthurian romance, Sir Kay is Arthur's foster brother and seneschal, usually portrayed as blunt and boastful, and the character kept the name long after the tales spread. The Welsh form "Cai" is the likely source of the modern given name, though its ultimate origin is uncertain. The informal interjection is the most recent sense. It works as a casual, quick signal of agreement, much like a clipped cousin of "okay."
