Morphology

crazy = craze (opaque) = craze + y

The contemporary adjective meaning 'mentally ill' is not transparently derived from the modern noun 'craze' (fad), so learners cannot reliably infer this sense from the base.

Etymology

Crazy originally suggested something 'cracked' or damaged, and people used that image for a mind that seemed not well. That's why crazy came to mean 'mentally ill'.
