Plunger → The word originates from the verb 'plunge' (from Old French *plonger*, meaning to dive or immerse) combined with the agent noun suffix '-er' (meaning a person or thing that performs an action). A plunger is a device that dives or immerses into a substance to create suction or pressure.
Think of a device that 'dives' ('plunge') into something to create suction — that's what a plunger does.
