Definition
A 'lunatic' is a person who is mentally ill, especially dangerously so, or wildly foolish. It is an outdated and often offensive term, now largely replaced by more respectful and accurate language. The term suggests erratic behavior influenced by the moon. The word can also describe someone who is utterly reckless or irresponsible. It implies a loss of reason and control. This term should be avoided in favor of more sensitive language. π
