The literary style that uses humor to criticize or mock is known as satire. This form of writing employs techniques such as exaggeration, irony, and parody to highlight flaws or absurdities in individuals, institutions, or societal norms. Satire serves not just to entertain, but also to provoke thought and inspire change by drawing attention to issues in a witty and often humorous manner. It has been a prominent literary tool throughout history, seen in works by authors such as Jonathan Swift and Mark Twain.
