Other forms: ejected, ejecting, ejects
To eject something is to throw it out with force. The player spits the disc back out at you, the rifle throws the empty cartridge sideways, the pilot pulls the handle and the whole seat fires clear of the plane.
People get ejected too, and there it means removed by force by someone with the authority to do it: a fan ejected from the stadium for throwing a bottle, a heckler ejected from the hall by two large men. Machines eject on command — press the button and the card, the tape, the toast comes out. The noun is ejection, and the seat that saves a pilot is an ejector seat, or an ejection seat in American writing. Eject is harder and more physical than remove; there is a shove in it.
Eject came through Middle French éjecter from Latin ēiectus, the perfect passive participle of ēiciō, 'to throw out'. That verb is ex, 'out', welded onto iaciō, 'to throw'. An ejector seat does exactly what the Romans described: it throws you out.
