IPA: /ɪˈdʒɛktər/
KK: /ɪˈdʒɛktər/
A device that forces out or removes something, often using a jet of air, water, or steam.

Ejector → It is formed from "e-" (meaning out) and "jacere" (meaning to throw). The word "ejector" refers to a device that throws something out or expels it.
Think of something that 'throws out' ('e-') an object — that's why an ejector is a device that expels something.
