plunger

PLUN-jer /ˈplʌn.dʒər/
nounB1
general

A tool consisting of a flexible rubber suction cup attached to a wooden or plastic shaft, used to clear blockages in drains and pipes.

Plunger refers to the manual suction tool, but in engineering, it can also refer to a reciprocating piston in a pump or syringe.

The story behind the word. Plunger is derived from the verb 'plunge', which comes from the Old French 'plongier' (to dive or dip). This traces back to the Vulgar Latin '*plumbicare', from Latin 'plumbum' (lead), referring to a lead weighted line used by sailors to measure water depth by dropping it quickly.
