The word 组合 is formed by combining two individual characters, each contributing a core meaning that merges into a single concept. The first character, 组 (zǔ), originally depicted a silken thread used to bind things together, carrying the inherent idea of organizing or grouping items. The second character, 合 (hé), pictographically represents a lid closing on a container, conveying the meaning to join, close, or unite. When placed together, 组 and 合 sequentially express the action and result of "forming a group by uniting separate parts", creating the comprehensive idea of a combination or assembly.
