Hyperbole (/haɪˈpɜrbəliː/ hy-PUR-bə-lee; Greek: ὑπερβολή hyperbolē, "exaggeration") is the use of exaggeration as a rhetorical device or figure of speech. It may be used to evoke strong feelings or to create a strong impression, but is not meant to be taken literally.
Hyperboles are exaggerations to create emphasis or effect. As a literary device, hyperbole is often used in poetry, and is frequently encountered in casual speech. An example of hyperbole is: "The bag weighed a ton." Hyperbole makes the point that the bag was very heavy, though it probably does not weigh a ton.
