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.

When a ship or an aircraft yaws當一艘船或一架飛機 yaw 的時候，its nose swings sideways — left or right —它的機頭或船頭會左右擺動，away from the direction it is meant to be going偏離原本應該前進的方向。The key idea is direction of the nose重點是機頭（或船頭）的方向，not the whole vehicle sliding across而不是整台交通工具橫向滑動。

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").

A gust of wind or a rough sea一陣強風或洶湧的海面，can make a plane or boat yaw都可能讓飛機或船發生 yaw。It is both a verb它既可以當動詞("the plane yawed to the left")（"the plane yawed to the left"，飛機偏航向左），and a noun也可以當名詞("a sudden yaw").（"a sudden yaw"，一次突然的偏航）。

This is a technical word from sailing, flying, and engineering; ordinary speakers rarely use it.

This is a technical word from sailing, flying, and engineering這是航海、飛行和工程領域的專業術語；ordinary speakers rarely use it一般人很少用到它。

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.

It is worth learning as part of a set of three值得把它當成一組三個詞一起學，because pilots and engineers always name them together因為飛行員和工程師總是把它們放在一起講：yaw is nose turning left and rightyaw 是機頭左右轉，pitch is nose going up and downpitch 是機頭上下擺，and roll is one wing dipping while the other risesroll 則是一邊機翼下沉、另一邊上升。

Robotics and computer graphics borrow the same three words for describing how anything turns in space, so students in those fields meet it too.

Robotics and computer graphics borrow the same three words機器人學和電腦繪圖也借用這同樣的三個詞，for describing how anything turns in space用來描述任何東西在空間中怎麼轉動，so students in those fields meet it too所以那些領域的學生也會遇到這個字。
