## Definition

a singer or band that performs before the main star at a concert.

For teachers: an entertainer or group that performs prior to the headline performer at a concert or show. The term implies a subordinate professional status relative to the main attraction.

## Examples

- The supporting act was actually better than the main band.
- We arrived early to see the supporting act, as they are a local band we really like.
- While the headliner garnered the most media attention, the supporting act delivered a surprisingly nuanced performance that captivated the early arrivals.

## Usage notes

- often used in the plural when multiple bands play before the main event.
- Teaching tip: contrast with 'headliner' or 'main act'; note that in American English, 'opening act' or 'opener' is a more common synonym.
