What is an example of hyperbole?

Hyperbole is a figure of speech that involves exaggerated statements or claims not meant to be taken literally, and it is often used for emphasis or humorous effect. The phrase "I'm so hungry I could eat a horse" is a clear example of hyperbole. It dramatically emphasizes the speaker's hunger by suggesting an implausible scenario where they could consume an entire horse, showcasing the intensity of their feeling.

The other phrases, while vivid in their imagery, do not fit the definition of hyperbole as tightly. For instance, "It's raining cats and dogs" is an idiomatic expression that indicates heavy rain but does not exaggerate to an absurd level. "She has a heart of stone" is metaphorical, suggesting someone is emotionally unfeeling, while "He runs faster than the wind" uses a comparison that, although extreme, does not reach the level of hyperbole typically intended for humorous exaggeration. Thus, the phrase about being able to eat a horse clearly reflects hyperbolic expression.
