IPA: /ˈtraɪ.dʒɛt/
KK: /ˈtraɪˌdʒɛt/
A type of aircraft that has three jet engines.
The trijet was designed for long-distance flights, providing more power and efficiency.
Trijet is a modern term formed from "tri-" (meaning three) and "jet" (from the French word "jeter", meaning to throw). The word refers to an aircraft with three jet engines, combining the idea of three with the function of jet propulsion.
Think of 'three' ('tri-') engines that 'throw' ('jet') the aircraft into the sky — that's what a trijet is.
