What is sardonic defined?

Sardonic is an adjective that refers to a mocking or sarcastic tone or attitude that is often bitter or humorous in nature. It conveys a sense of detachment or contempt towards the subject or person being mocked. Sardonic remarks or comments are designed to be cutting and caustic, often to the point of being cruel. The word derives from the Greek island of Sardinia, where a plant called the Sardinian fenugreek was believed to cause facial paralysis, resulting in a grotesque, twisted smile that was seen as the hallmark of a sardonic grin. The use of sardonic humor is common in literature, satire, and social media.
