Morphology

madman = mad + man (transparent) = mad + man

The compound is a straightforward combination 'mad' + 'man' meaning 'a man who is mad', which learners can derive from the parts.

Etymology

The word madman is simply mad + man, and mad long ago meant 'out of one's mind' or 'insane'. So a madman is literally a man who is 'out of his mind', which explains why we use it for someone who behaves wildly or dangerously.
