About
The character "枵" is structured with the radical "木" indicating wood or tree and the component "号" functioning phonetically while contributing a connotation of emptiness, originally denoting a hollow tree. Its meaning expanded from this specific physical hollowness to describe general states of emptiness, such as an empty stomach in the compound "枵腹", and further to imply thinness or emaciation, reflecting a semantic broadening while its compositional elements remain evident in its form.
