repetoire

Repertoire is the set of skills, pieces, or works that a person or group can perform or produce. In the arts it commonly refers to the catalog of musical works or plays that a performer or company can present. More broadly, it can denote the range of techniques, strategies, or material a person can draw on in professional practice.

Etymology: The word comes from French repertoire, from Late Latin repertorium, meaning a catalog or inventory. The usual English spelling is repertoire; repetoire is a common misspelling.

Usage in different fields: In music and theatre, repertoire is the collection of pieces a musician, ensemble, or troupe has learned and can perform on demand. Musicians often expand their repertoire by learning new works. In education, work, and everyday life, repertoire refers to the set of skills, methods, and resources a person can apply. In linguistics and sociolinguistics, a speaker’s repertoire can describe the range of languages, dialects, registers, and styles they can use. Some discussions in biology or animal behavior also speak of a repertoire to describe the range of vocalizations or actions an a species or individual can produce.

Notes on usage: The term emphasizes both the inventory itself and the ability to draw from it. Phrases such as “drawing from one’s repertoire” or “expand the repertoire” are common in performance contexts and in professional development.
