Bleachers are the long rows of benches or seats, arranged in rising tiers like stairs, where spectators sit to watch sporting events or performances. You've probably sat on bleachers at a school basketball game, a baseball field, or an outdoor concert. They're called bleachers because in the 1800s, these uncovered wooden seats were left out in the sun and weather, which bleached them lighter over time.

Bleachers are designed so that each row sits higher than the one in front, giving everyone a clear view over other people's heads. This simple but clever arrangement means hundreds of people can watch the same game without anyone blocking anyone else's view. Modern bleachers might be made of metal or plastic instead of wood, and some have backrests, but the basic stepped design remains the same.

The word often appears in phrases describing where something happens: a dramatic moment might unfold in the bleachers, or a player might hit a home run into the bleachers. Sitting in the bleachers puts you right in the middle of the crowd's energy, close enough to hear the crack of the bat or feel the excitement ripple through hundreds of fans at once.
