## Definition

a style of acting or music where the performers make everything up as they go. There is no script, so they have to react quickly to each other.

For teachers: performance art, particularly comedy or theatre, created spontaneously without a script or prior preparation. Often used as a modifier in compound nouns like 'improv group' or 'improv class'.

## Examples

- We went to see an improv show last night.
- The actors asked the audience for a location and a random object to start their improv scene.
- While improv appears entirely chaotic to the uninitiated, it actually relies on a strict set of internal rules, such as the 'yes, and' principle, to maintain narrative momentum.

## Usage notes

- Commonly functions as an attributive modifier before other nouns; informal shortening of 'improvisation'.
