repertory

A repertory is not just any collection. It is the full set of plays, songs, dances, or other pieces that a person or group is ready to perform or use. Think of a ballet dancer: their repertory includes the ballets they have learned and can dance. A theater company may have a large repertory of plays, and a singer may build a repertory of songs over many years. The word comes from the Latin repertorium, meaning "a place where things are stored."

It once referred to a collection of medicinal remedies, a doctor's "storehouse" of treatments. Today, it is used most often in the performing arts, though it can also describe someone's usual set of stories, ideas, or other material they can draw on when needed.

The word "repertory" refers to the full stock of plays, songs, dances, or other pieces that a person or group is ready to perform or present. It suggests a collection that has been learned, practiced, and kept ready for use. For example, "The pianist had a vast repertory of classical music" means that the pianist could play many different pieces.

Historically, the term was also used in medicine for a collection of remedies kept by physicians, essentially a "storehouse" of treatments. That older meaning helps explain the basic idea behind the word: a body of material kept ready to be used when needed.

Today, "repertory" is most common in the performing arts. A theater company's repertory consists of the plays it is prepared to stage, often rotating among them during a season. In the same way, a dancer's repertory includes the ballets or modern works they have learned and can perform.

The word can also extend beyond the stage. You might say someone has "a rich repertory of anecdotes," meaning they have many stories ready to tell. In broader use, it can mean a familiar stock of material, though this is less central than the performance sense.

So whether you are talking about an actor's roles, a musician's pieces, or even someone's well-used set of stories, a repertory is a body of material kept ready for performance, presentation, or use.
