Etymology
Origin of madman
First recorded in 1300–50, madman is from Middle English madd man. See mad, man
Explanation
Madman is an old fashioned, derogatory term for a severely mentally ill person. These days, calling someone with a serious psychiatric illness a madman would be offensive. You're most likely to hear dangerous criminals described as madmen, although it's also common to use this word for someone who acts recklessly: "Look how fast that madman is driving!" Another way to use madman is to emphasize the intensity of something: "She worked on that paper like a madman, writing the entire thing in just a few hours."
