A person who is very famous and successful, especially in entertainment or sports, and is admired by many people.
The concert was sold out because the superstar was performing.
**Superstar** → It is formed from "super-" (meaning above or beyond) and "star" (from Old English "steorra", meaning celestial body). The word "superstar" refers to a star that is above or beyond others in fame or talent.
Think of someone who is a 'star' but even 'above' ('super-') the rest — that's why a superstar is someone exceptionally famous or talented.
