IPA: /ˈfleɪm.aʊt/
KK: /ˈfleɪmˌaʊt/
A sudden failure or cessation of operation, especially in a jet engine, or a quick end to success in a person's career.
The pilot managed to land safely after experiencing a flameout during the flight.
Flameout is formed from "flame" (from Old English *flama*, meaning a burning fire) and "out" (meaning away from or outside). The term describes the extinguishing or dying out of a flame, often used in contexts like engines or fires.
Think of a 'flame' that is 'going out' — when a flame 'dies down' or extinguishes, that's what a flameout means.
