The word 负责人 is formed by combining three individual characters: 负 (fù), which conveys the idea of bearing or carrying a burden; 责 (zé), which means duty or responsibility; and 人 (rén), meaning person. When read sequentially, the characters conceptually stack to create the composite meaning of "the person who carries the burden of responsibility", visually and semantically building from the act of shouldering (负) a specific duty (责) onto an individual (人).
