The word "star" refers to a massive celestial body that emits light and heat, typically made up of gases like hydrogen and helium. Stars are found in galaxies and can be seen from Earth as bright points of light in the night sky. The term "star" can also be used metaphorically to describe someone who is very talented, famous, or successful in a particular area, such as a "movie star" or a "rock star."
The word "star" comes from the Old English "steorra," which is derived from the Proto-Germanic "sternō," and the Proto-Indo-European root "h₂stḗr" meaning "star."
