Caysi is a name of American origin, believed to have been created by the author Stephen King for his character in the TV series "Kingdom Hospital". It is not a traditional name with a long history or a well-known meaning. As it was created by an author for fictional purposes, its significance and origin are tied to that context alone. There is no widely accepted etymology or cultural background associated with the name Caysi outside of Stephen King's works.
