The Chinese word 司令部 (sīlìngbù), meaning "headquarters" or "command," is a compound noun formed through a logical and hierarchical semantic combination. It is constructed from three morphemes: 司 (sī), which means "to take charge of" or "administer"; 令 (lìng), meaning "order" or "command"; and 部 (bù), meaning "department" or "ministry." Thus, the term conceptually progresses from the action of managing (司) to the specific function of issuing commands (令), all contained within an organized unit or department (部). This creates the integrated meaning of a "command-administering department," or the central body from which orders are issued and operations are controlled.
