Final answer:
Hyperbole is a rhetorical device used to create emphasis through exaggeration. It can add humor, create strong impressions, or convey deep emotions in literature and everyday speech.
Step-by-step explanation:
Words or phrases that tend to be viewed as exaggerations are known as hyperbole. Hyperbole is a rhetorical device that is used to create emphasis by overstating facts, figures, or feelings. For example, the statement "I'm so hungry I could eat a horse" is hyperbolic because it exaggerates the speaker's level of hunger.
In literature, hyperbole can be employed to add humor, create strong impressions, or convey deep emotions. One example comes from Wordsworth's "I wandered lonely as a cloud" where the phrase "ten thousand saw I at a glance" is used to express the overwhelming number of daffodils, which serves to evoke a powerful image even though the exact count is not literal.
