Lunacy means insanity or craziness. It is usually used to describe behavior that is very strange or irrational, often resulting from a mental illness or disorder. The word is commonly used in contexts such as legal proceedings or discussions of mental health. However, it can also be used more informally to describe wild or irrational behavior in everyday life. For example, someone might say "It's pure lunacy to go skydiving without a parachute."
