The word 成绩单 (chéngjìdān), meaning "report card" or "transcript," is a compound noun formed through semantic combination: the first element 成绩 (chéngjì) means "achievement" or "grade," and the second element 单 (dān) means "list" or "sheet." Together, they logically and directly describe a documented list of academic grades, following the common Chinese word-formation pattern where a modifier (成绩) specifies the type of document (单).
