sarcophagus: [17] A sarcophagus is etymologically a ‘flesh-eater’: the word comes via Latin sarcophagus from Greek sarkophágos, a compound formed from sárx ‘flesh’ (source of English sarcasm) and -phágos ‘eating’. This originated as the term for a particular type of limestone that in the ancient world was used for making coffins, since bodies buried in them quickly decomposed. By extension it came to be used for the coffins themselves. => sarcasm[sarcophagus etymology, sarcophagus origin, 英语词源]
