Which device is an exaggeration used for emphasis or effect?

Hyperbole is a figure of speech that uses deliberate exaggeration for emphasis or dramatic effect. It's not meant to be taken literally but serves to create a strong impression or evoke a particular emotion. For instance, "I'm so hungry I could eat a horse" is a hyperbolic expression of hunger. Hyperbole is commonly used in literature, poetry, and everyday language to add humor or emphasis to a statement. It can also be a useful tool for writers looking to make their writing more engaging and memorable.
