The kanji 革 primarily means "leather" or "skin" (especially animal skin that has been treated for use). It also extends to mean "to reform" or "to change" because the process of turning raw animal hide into leather involves transforming it. It represents something that has undergone a significant alteration or processing.

The kanji 革 is a pictograph. It depicts the shape of animal hide that has been stretched out and prepared for use. The top part represents the animal's back, and the bottom part depicts the legs, which are stretched out during the tanning process. The radicals on either side of the kanji represent the processes the skin goes through. The transformation from raw hide to leather is what the kanji represents.
