'尸体' (shī tǐ) literally combines '尸' (shī), meaning 'corpse' or 'dead body' — historically also referring to a ceremonial stand-in for the deceased in ancient rituals — and '体' (tǐ), meaning 'body' or 'physical form'. Together, they form a formal, clinical, and respectful term for a human corpse, emphasizing physical remains after death. It is neutral in tone but carries gravity; it’s commonly used in medical, legal, forensic, and news contexts, not in casual or emotional speech.

The word avoids colloquial or euphemistic connotations — unlike terms like '遗体' (yí tǐ, 'remains', more respectful and often used in funerary contexts) or '死尸' (sǐ shī, 'dead corpse', blunt and sometimes pejorative). '尸体' appears frequently in official reports, autopsy records, disaster response, and public health discussions where factual precision matters more than sentiment.
