Klarissa is a name of Greek origin that means "bright" or "clear". It is derived from the Greek word "klaros", which means "clear" or "famous". The name Klarissa has been used since ancient times, but it became more popular in the Middle Ages when it was adopted by several saints and martyrs. Today, Klarissa remains a relatively rare name, but it is still used around the world as a unique and distinctive choice for girls.
The name Klarissa is not particularly common in the United States, with only six babies born with this name each year on average since its first appearance in the Social Security Administration's records in 1997.
