stopper

This term evokes the physical act of sealing or blocking a passage to prevent leakage or movement. It is most commonly associated with household objects like wine bottles or bathtubs, where it creates an airtight or watertight seal. In athletic contexts, the word shifts from a physical object to a functional role, describing a player whose primary objective is to halt the momentum of the opposing team. This usage emphasizes obstruction and defensive stability rather than a physical plug.
