The word 狂热 is formed by combining two vivid conceptual images: 狂, which conveys a sense of wild, unrestrained, and almost manic intensity, with 热, which represents the physical sensation and metaphor of heat, fervor, or passion. Together, they create a powerful compound where the "wildness" directly modifies and intensifies the "heat", resulting in the meaning of a feverish, extreme, and all-consuming zeal. It is the embodiment of passion that has boiled over into frenzy.
