The word "警官" is formed by directly combining two meaningful characters: "警" (jǐng), which signifies 'police' or 'alert,' and "官" (guān), which means 'official' or 'officer.' It is a conceptual compound where the first element defines the field or domain (police matters), and the second element specifies the rank or role of a person within that domain (an official). Thus, the characters are merged to create the single, unified title for a "police officer", representing an official within the police sphere.
