Hyperbole is a figure of speech that involves exaggerated statements or claims not meant to be taken literally. It is often used for emphasis or to create a strong impression. For example, saying "I'm so hungry I could eat a horse" illustrates extreme hunger without intending to consume an actual horse. This literary device is commonly found in everyday language, literature, and advertising. Writers and speakers use hyperbole to add humor or drama to their expressions. Phrases like "I've told you a million times" highlight the speaker's frustration, showcasing how hyperbole can enhance communication by making it more vivid and engaging.
