The word 结合 is formed by combining two individual characters, each contributing its core meaning to create a new, unified concept. The first character, 结 (jié), originally depicts silk threads tied together, carrying the essential idea of "connecting" or "binding". The second character, 合 (hé), pictographically represents a lid closing on a container, conveying the idea of "joining" or "merging". When paired, these characters do not simply add their meanings but fuse them into a single, coherent concept of "to combine" or "to integrate", where separate elements are connected and joined to form a unified whole.
