What does improv mean?
Improv is an informal word for spontaneous performance, especially in comedy and theatre. As a noun, it can mean an improvised act, scene, or theatrical performance created without a prepared script; as a verb, it means to respond to circumstances by producing words, actions, or solutions on the spot. Performers typically work from broad suggestions rather than fixed lines, using quick listening, imagination, and agreement with one another to develop a scene. Outside the theatre, “improvise” often suggests resourcefulness: improvising a meal, a plan, or a solution to a problem. The word can suggest spontaneity and creativity, but it may also imply that the result was not carefully prepared. Its vocabulary sense comes from the broader tradition of improvisation, while its shortened theatrical form became established in the twentieth century.
