The word "lunatic" comes from the Latin word "lunaticus", which means "moonstruck" or "affected with periodic insanity". The term "lunaticus" was derived from the Latin word "luna", meaning "moon". In ancient times, people believed that changes in the moon could cause temporary mental disorders or madness.
