sweeper

A "sweeper" is not just someone who cleans a floor. The word can mean a person or a machine that clears away dirt, dust, or trash, but it also has special uses in sports and games. In soccer, for example, a sweeper is a defender who stays behind the main line of defense and deals with loose balls or danger that gets through.

The main idea behind the word is clearing things away. It can point to a street-cleaning machine, a player in curling who sweeps the ice, a defender who clears attacks, or in some games, a card or move that clears many pieces at once. In baseball, it can also mean a pitch that moves strongly across the strike zone.

The word "sweeper" starts with the simple idea of sweeping something away. In its most literal sense, it can mean a person who cleans floors, streets, or other spaces by brushing away dirt and trash. It can also mean a machine that does this job, such as a street sweeper or a carpet sweeper. In both cases, the focus is on clearing a surface and making it clean again.

From there, the word spread into sports. In soccer, a sweeper is a defender who plays behind the other defenders and clears away dangerous balls that get past them. In curling, a sweeper is one of the players who brushes the ice in front of the stone to help control its speed and path. In baseball, "sweeper" is also used for a pitch with strong side-to-side break.

The word also appears in games. In many modern board, video, and trading card games, a sweeper is a card, move, or effect that clears many pieces, creatures, or threats from play at once. This use keeps the same basic image: something comes through and wipes the space clean.

Across these uses, the meaning stays consistent. A sweeper is usually a person, machine, player, pitch, or game effect that clears, covers, or removes what is in the way. Even when the setting changes, the word keeps that sense of moving through a space and cleaning it out.
