The word 先斩后奏 is formed by the direct sequential combination of four characters: 先 (first) precedes 斩 (behead), and 后 (later) precedes 奏 (report), creating a literal meaning of "behead first, report later". This structure depicts a specific order of actions where the act of execution occurs before the act of notification, originating from historical contexts where authority was exercised immediately with subsequent accountability.
