  1. 1偏航（機頭或船頭左右偏擺）

    When a ship or an aircraft yaws, its nose swings sideways — left or right — away from the direction it is meant to be going. The key idea is direction of the nose, not the whole vehicle sliding across. A gust of wind or a rough sea can make a plane or boat yaw. It is both a verb ("the plane yawed to the left") and a noun ("a sudden yaw"). This is a technical word from sailing, flying, and engineering; ordinary speakers rarely use it. It is worth learning as part of a set of three, because pilots and engineers always name them together: yaw is nose turning left and right, pitch is nose going up and down, and roll is one wing dipping while the other rises. Robotics and computer graphics borrow the same three words for describing how anything turns in space, so students in those fields meet it too.

組成Origin unknown; first recorded in the mid-16th century. It may be linked to old words for moving quickly or being driven back and forth, but scholars are not agreed, so treat that as a guess rather than a fact.
