Etymology
The word 'motor' has a direct lineage from the Latin verb 'movēre', meaning 'to move'. Its core morpheme, 'mot-', derives from the past participle 'mōtus' (having been moved). The suffix '-or' is a classic Latin agentive ending, attached to verb stems to denote an instrument or performer of an action. Thus, the literal construction yields "a thing that causes movement." Initially used in the 15th century for a prime mover or source of motion, its meaning narrowed and became dominant in the late 19th century with the invention of the electric motor and the internal combustion engine, solidifying its modern association with mechanical power sources.
Analysis
