Etymologies
- French sardonique, from Latin sardonius, from Ancient Greek σαρδόνιος (sardonios), alternative form of σαρδάνιος (sardanios, "bitter or scornful laughter"), which is often cited as deriving from the Sardinian plant (Ranunculus sardous), known as either σαρδάνη (sardanē) or σαρδόνιον (sardonion). When eaten, it would cause the eater's face to contort in a look resembling scorn (generally followed by death). It might also be related to σαίρω (sairō, "I grin"). (Wiktionary)
- French sardonique, from Greek sardonios, alteration of sardanios. (American Heritage® Dictionary of the English Language, Fourth Edition)

snapd Sorry for any confusion: I am not sure my note was accepted to my suggested word 'sardony'
There seem to be many words which lack a complete complement of forms. Sardonic is one of them. I cannot say "I am tired of your sardony" in a manner similar to how I can say "I am tired of your anger". Instead I must always attach a noun or verb to the adjective or adverb. Is there a name for these kinds of imperfect or irregular words? As a class, do they derive particularly from any linguistic river that has contributed to English? Should there not be a word 'sardony'? Jul 22, 2009

Sardonic:
Bitter derision, usually ironic: intended to be humorous.
Difference: Sardonic and Sarcastic
Sarcasm is more general than sardonicism. It can be humorous (at the cost of others), acidic, dry, or similar. To tell the 'type' of sarcasm, you must know the context.
Sardonicism implies a negative view of something. It's sarcasm with an ill tone, even if it's used for humour. Someone can use sardonicism but it's obvious that he isn't too comfortable with subject. Jul 13, 2009
