About
The character 啮, meaning to bite or gnaw, originates from the traditional form 齧, which semantically integrated the component 齒 for teeth. Its simplified structure substitutes 齒 with 口 for mouth and modifies the right-hand element to 臬, altering the compositional logic. The core meaning of biting has remained primary, though it has expanded to describe mechanical interlocking, as in the term 啮合 for gear meshing.
