Aerospace: Definition, Examples, and Key Usage (2 meaning)
Meaning 1：aerospace industry (aerospace)
aerospace
/ˈɛrəˌspeɪs/
n.
The business and technology of making airplanes and spacecraft.
aerospace industry
➕
/ˈɛrəˌspeɪs ˈɪndəstri/
n.
The sector of the economy and technology focused on the design, production, and operation of aircraft and spacecraft.
📘 Details & Usage
📖 Root Explanation
From 'aero-' (air) + 'space', referring to the combined realm of aviation and outer space.
💡 Mnemonic
Air + space = aerospace: think of an airplane flying into space.
