What is the definition of hyperbole?

The definition of hyperbole is indeed excessive exaggeration used for humor or emphasis. This literary device is often employed to create a strong effect and is commonly recognized in both spoken and written language. For example, saying "I'm so hungry I could eat a horse" is an exaggerated statement that highlights the speaker's hunger in a humorous way, rather than being taken literally.

Hyperbole is different from other literary devices. Comparisons using "like" or "as" define similes, which are distinct from hyperboles because they do not focus on exaggeration. Words that imitate sounds, known as onomatopoeia, also serve a different purpose, as they aim to replicate auditory experiences rather than emphasize or exaggerate. Lastly, a phrase understood to have a different meaning refers to idioms, which convey meanings beyond the literal interpretation of the words used.

Through humor or emphasis, hyperbole captivates the audience's attention and often conveys the emotional condition of the speaker in a relatable way.
