The word "双方" is formed by combining two individual characters: "双" (shuāng), which means "pair", "double", or "two", and "方" (fāng), which means "side", "direction", or "party". Their combination is purely conceptual, where the notion of "a pair" ("双") is directly applied to the notion of "sides" ("方"), resulting in the composite meaning of "two sides" or "both parties". It is a direct semantic fusion where the first character quantifies the second, creating a new, specific idea from its constituent parts.
