The word 司法 is formed by combining two characters: 司, which means to take charge of or administer, and 法, which means law. Together, they create a concept where the action of administering (司) is directly applied to the domain of law (法), resulting in the composite meaning of "judicial affairs" or "the administration of justice". It is a conceptual fusion where one character denotes the action and the other specifies the object of that action, forming a precise term for the execution and management of legal authority.
