Definition
对偶 is a noun with two distinct technical senses. In rhetoric and literature, it refers to a pair of parallel phrases or lines that are balanced in structure and meaning — a common device in classical Chinese poetry and prose. In mathematics, it describes a dual relationship or duality between two objects or structures (e.g., in geometry or algebra). The context (literary vs. mathematical) determines which sense is intended.
