The word 死尸 is a Chinese compound noun formed through semantic compounding, where two independent characters, each with their own meaning, are combined to create a more specific term. The first character, 死 (sǐ), means "dead" or "death", functioning as an attributive modifier. The second character, 尸 (shī), means "corpse" or "body". When combined, 死 directly modifies and intensifies 尸, explicitly specifying a "dead corpse" or simply "cadaver". This structure is typical in Chinese for creating precise, literal descriptions, eliminating any ambiguity that might arise from using 尸 alone, which could occasionally have archaic or extended meanings.
