The word 成绩 (chéngjì) is formed by combining two characters, each contributing a core idea to create a new, unified concept. The first character, 成 (chéng), carries the meaning of "to accomplish", "to complete", or "to become". The second character, 绩 (jì), originally referred to the twisting of fibers into thread or the weaving of cloth, thus metaphorically extending to mean "achievement" or "merit". Together, they create a powerful image: 成绩 represents the "accomplished threads" or the "completed weave", that is, the tangible results, fruits, or record of one's efforts and labor, such as academic grades or work performance.
