Etymology

Origin of cheerleader

An Americanism dating back to 1900–05; cheer + leader

Explanation

A cheerleader is a member of a team that performs synchronized cheers and dance routines, usually from the sidelines of a game. The best cheerleaders are extremely strong and flexible, with a great sense of rhythm. The main job of a cheerleader is to rally a sports team to victory, although many cheerleaders also perform complex acrobatic routines. The traditional uniform that a cheerleader wears includes a short skirt or shorts. In the late 19th century, cheerleaders were simply college students in the stands who called out school cheers in unison. By the 1890s, official cheerleading squads were formed, originally including only men — no women or girls were cheerleaders until 1923.
