sardonicallysardonic
Sardonic comes from the Greek adjective Sardonios, which actually describes a plant from the island of Sardinia that supposedly made your face contort into a horrible grin...right before you died from its poison. The Greeks used sardonic for laughter, but we only use it when someone's humor is also mocking or ironic.
