Root Explanation

Costar is formed from "co-" (meaning together) and "star" (from Old English "steorra", meaning a celestial body). The word "costar" refers to an actor who shares the stage or screen with another actor, thus performing together as stars.

Memory Tip

Think of actors performing 'together' ('co-') as 'stars' on stage or screen — that's what a costar is.
