propeller

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.

Structure: pro (forward) + pel (drive) + ler (agent suffix) - pro: Latin origin, a prefix meaning "forward" or "forth". - pel: From Latin pellere, meaning "to drive" or "to push". - ler: An English agent noun suffix, variant of '-er', indicating "a person or thing that performs an action".
