Hyperbole ( /haɪˈpɜrbəliː/ hy-pur-bə-lee;[1] Greek: ὑπερβολή, '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."[2] Hyperbole helps to make the point that the bag was very heavy, although it is not probable that it would actually weigh a ton.
In rhetoric, some opposites of hyperbole are meiosis, litotes, understatement, and bathos (the 'letdown' after a hyperbole in a phrase).
