飞机用英语是表示为 "airplane" 或 "aeroplane"。

这个词的来源可以追溯到古希腊语，"aero-" 来自古希腊语的 "aer"，意思是 "air"，而 "-plane" 来自古希腊语的 "planos"，意思是 "wandering" 或 "wandering about"。所以，原意为 "something that wanders about in the air"，后来演变成了现在的意思，即 "a vehicle that is able to fly through the air, typically by being supported by the air on which it moves"。

以下是一些英文例句及其中文翻译：

"I'm going to take the airplane to Paris next week."（我下周要坐飞机去巴黎。）
"The airplane flew over the city at an altitude of 10,000 feet."（飞机在一万英尺的高度飞过这座城市。）
"I'm afraid of flying in airplanes."（我害怕坐飞机。）
"The airplane was delayed due to bad weather."（由于恶劣天气，飞机延误了。）
