Are there any differences between the word ” Sarcastic ” and ” Sardonic ” ?
Here is a summary of the meaning of various adjectives that are related but are slightly different in meaning. It includes the two you mention. I hope this helps clarify it for you. These adjectives mean having or marked by a feeling of bitterness and a biting or cutting quality. Sarcastic suggests sharp taunting and ridicule that wounds: “a deserved reputation for sarcastic, acerbic and uninhibited polemics” (Burke Marshall). Ironic implies a subtler form of mockery in which an intended meaning is conveyed obliquely: “a man of eccentric charm, ironic humor, and—above all—profound literary genius” (Jonathan Kirsch). Caustic means corrosive and bitingly trenchant: “The caustic jokes … deal with such diverse matters as political assassination, talk-show hosts, medical ethics” (Frank Rich). Satirical implies exposure, especially of vice or folly, to ridicule: “on the surface a satirical look at commercial radio, but also a study of the misuse of telecommunications” (Richard Harrington).
