driverless

The word 'driverless' is a modern English compound formed by combining the agent noun 'driver' with the privative suffix '-less'. The root 'drive' traces back to Old English drīfan, meaning "to propel, urge forward," which itself has Proto-Germanic origins. The suffix '-less', from Old English -lēas, originally meant "devoid of" and is used to form adjectives indicating the absence of a quality. Therefore, the literal construction "driver + less" logically yields the contemporary meaning of "operating without a human driver," a term that gained prominence with the development of autonomous vehicle technology.
