The Chinese word 文书 is a compound noun formed through the combination of two independent morphemes: 文, which broadly means "writing", "document", or "language", and 书, which means "to write", "writing", or "book". Together, they create a coordinative compound where each part contributes a related meaning, combining to specify a category of formal, written materials. The term thus refers to official documents, legal instruments, or clerical paperwork, essentially capturing the concept of "written documents" as a unified whole through the semantic fusion of its two constituent characters.
