driver
UK: ˈdraɪvə | US: ˈdraɪvər
n. a person who operates a vehicle (e.g., car, bus)
n. a tool or device that drives something (e.g., screwdriver)
n. (computing) software that controls hardware
The word "driver" combines the verb "drive" (from Old English drīfan, meaning "to push or propel") with the agent suffix "-er," which denotes a person or thing performing an action. Originally tied to physical propulsion (e.g., driving livestock), its meaning expanded to include operating vehicles and later, in computing, controlling hardware. The suffix "-er" is a productive morpheme in English, consistently forming nouns from verbs.

He’s a cautious driver who always obeys speed limits.
