The word 警徽 is formed by combining two characters, each contributing a core meaning to create a new, specific concept. The first character, 警 (jǐng), conveys the idea of "police", "alert", or "guard". The second character, 徽 (huī), means "emblem", "badge", or "insignia". They are joined in a straightforward, logical combination where the first element defines the domain (police) and the second specifies the type of object (emblem), resulting in the complete meaning: "police emblem" or "police badge".
