A formal dance or ball, often for young people, where they are introduced to society.
The school held a cotillion to celebrate the students' graduation.
Cotillion comes from the French word *cotillon*, meaning a small coat or petticoat, which is derived from *cotille*, meaning a short skirt. The term evolved to refer to a type of dance that was originally performed in a lively manner, often in a social setting. Thus, cotillion refers to a formal dance or ball, particularly one that involves a specific set of movements and formations.
Imagine a lively dance where people are dressed in their best, just like the 'small coat' ('cotillon') that inspired the name. This helps you remember that a cotillion is a formal dance or ball.
