About
The character "跗" is structured with the foot radical ⻊ combined with the phonetic component 付, linking it semantically to the foot while indicating its pronunciation. Etymologically, it initially referred to the instep or the top surface of the foot. Over time, its application became more specialized, narrowing to denote the anatomical area around the ankle or the tarsal bones in technical contexts, a shift that occurred without alteration to the character's compositional form.
