sarcasm: [16] A sarcastic remark is etymologically one which involves the ‘rending of flesh’. Greek sárx meant ‘flesh’ (it has given English sarcoma [17] and sarcophagus), and it formed the basis of a verb sarkázein ‘tear the flesh’, hence ‘bite one’s lip, gnash one’s teeth’, and by further extension ‘make a cutting remark’. This gave rise to the late Greek derivative sarkasmós, which passed into English via late Latin sarcasmos and French sarcasme.
