About
The character "趼" etymologically relates to calluses on the foot, evident from its structure featuring the "足" radical denoting the foot. Its traditional form incorporates the component "幵" alongside "足", whereas the simplified form substitutes "幵" with "开". Historically, the character specifically indicated hardened skin on the sole caused by friction, and its meaning has not expanded to include calluses on other parts of the body, remaining focused on this physical attribute.
