Etymology

Origin of heady

First recorded in 1350–1400, heady is from the Middle English word hevedy, hedy. See head, -y 1

Explanation

Something that's heady is extremely thrilling. You might have a heady feeling as you walk up on stage to get your high school diploma. Use the adjective heady to describe a sensation that is so exciting it makes you a little dizzy, a bit like being intoxicated. You could talk about the heady scent of your mom's rose garden or the heady feeling of winning the state spelling bee. The fourteenth century meaning of heady was "headstrong or impetuous," and it's sometimes still used in this way. By the 1570's, it had also come to mean "apt to go to the head," or "exhilarating."
