The word 腰带 is formed by combining two characters: 腰 (yāo), which pictographically represents the "waist" or "loins" of the human body, and 带 (dài), which depicts a "belt" or "sash" as a long piece of cloth. Together, they create a direct, compound image where the second element (带) specifies the object, and the first (腰) specifies its location and function, visually and conceptually merging into the single, concrete item "waistband" or "belt".
