Metaphor, hyperbole, and irony are figurative language techniques found in speeches, each serving different purposes in conveying meaning.
Metaphor: A metaphor establishes a relationship of resemblance between two ideas or things by equating or replacing one by the other. In Franklin D. Roosevelt's inaugural address, the excerpt uses the phrase 'the withered leaves of industrial enterprise lie on every side,' where the withered leaves represent the decline of industrial enterprises.
Hyperbole: Hyperbole is intentional exaggeration for effect. In Ronald Reagan's joke about his age, stating 'The chamber is celebrating an important milestone this week: your 70th anniversary,' the exaggeration emphasizes the humorous aspect.
Irony: Irony is the expression of meaning using language that signifies the opposite. When individuals use irony, they may mean something different from what is said. It adds a layer of complexity and depth to communication.
