Etymology
The word 'propeller' is a modern English formation, built upon the verb 'propel'. 'Propel' itself entered English in the 15th century from the Latin propellere, a compound of pro- ("forward") and pellere ("to drive, push"). The core root pel- is of Proto-Indo-European origin, carrying the fundamental sense of "to thrust, strike, drive," which is also visible in words like pulse, repel, and expel. By adding the agent suffix '-er', the noun 'propeller' was logically created to denote "a thing that drives forward," perfectly capturing the function of the rotating blades that drive ships and aircraft through their respective mediums.
