Can i get an example of something sardonic? I'm confused, what is the difference between sardonic and sarcastic?
Sarcastic is more "biting" - more caustic. In fact, it comes from a Greek word meaning "to bite the lip in anger". Example -- "If peace were measured by the number of dead, W should get the Nobel peace prize."
Sardonic can be caustic, but with more deliberate humor (from the Greek word for a plant that causes one to smile or laugh). Example: James Brady, when he was Reagan's press secretary, was lambasted by a reporter as he was beginning a press conference, and his reply was -- "Whatever happened to foreplay?"
