The Chinese word "邮报" (yóubào) is a nominal compound formed by combining two meaningful characters: "邮" (yóu), which means "mail" or "postal," and "报" (bào), which means "newspaper" or "report." Together, they create a new word that literally translates to "mail newspaper," historically referring to a publication distributed via the postal system. This type of formation, where two independent nouns are juxtaposed to specify a category (a newspaper associated with mail delivery), is a standard and productive method in Chinese for creating compound words, and it is commonly used in the titles of publications, such as in "华盛顿邮报" (The Washington Post).
