Did you know? In the heyday of large sailing ships, numerous nautical words appeared on the horizon, many of which have origins that have never been traced. "Yaw" is one such word. It began showing up in print in the 16th century, first as a noun (meaning "movement off course" or "side to side movement") and then as a verb. For more than 350 years it remained a sailing word, with occasional side trips to the figurative sense "to alternate." Then dawned the era of airplane flight in the early 20th century, and "yawing" was no longer confined to the sea. Nowadays, people who love boats still use "yaw" much as did the sailing-men of old, but pilots and rocket scientists also refer to the "yawing" of their crafts. *Indicates the sense illustrated in the example sentence.
