Which literary device is used to exaggerate for emphasis or effect?

The literary device used to exaggerate for emphasis or effect is hyperbole. This technique involves crafting statements that are intentionally overstated to create a strong impression or to convey intense feelings. For example, saying "I'm so hungry I could eat a horse" is an exaggerated way to express extreme hunger.

Hyperbole is effective because it draws the reader's attention and can add humor or drama to writing. It helps to emphasize a point and can evoke a strong emotional response from the audience. Understanding hyperbole allows readers to appreciate the creativity in language and recognize when an author is employing this device for a particular effect.

In contrast, similes and metaphors involve comparisons that are not necessarily extreme, while imagery focuses on creating vivid pictures in the reader's mind. Each of these devices serves a unique purpose, but hyperbole specifically thrives on exaggeration.
