Etymology
the word 'ejector' is built upon the latin verb 'eicere', meaning 'to throw out', which itself is a compound of the prefix 'ex-' (out) and the verb 'iacere' (to throw). the english form 'eject' emerged in the late 15th century, derived from the past participle 'ejectus'. the agent suffix '-or' was then appended, following a common latin pattern to denote an instrument or person performing an action. thus, an ejector is literally 'that which throws out', a meaning directly preserved in its modern technical applications, from firearms to aircraft seats.
Analysis
Structure: e (out) + ject (throw) + or (agent suffix)
e- (latin origin, prefix meaning 'out'); -ject- (latin origin, root from 'iacere' meaning 'to throw'); -or (latin origin, agent noun suffix meaning 'a person or thing that does something').
