What literary device is characterized by overexaggeration to emphasize a point?

Hyperbole is the literary device that involves exaggerated statements or claims that aren't meant to be taken literally. This overexaggeration is used for emphasis or to create a strong impression in the reader's mind. For example, if someone says, "I've told you a million times," they don't literally mean they've said it a million times; rather, they're emphasizing how often they have repeated themselves.

In contrast, metaphor, imagery, and simile serve different functions. A metaphor makes a direct comparison between two unlike things without using "like" or "as," suggesting a similarity or shared quality. Imagery involves using descriptive language to create visual representations that engage the senses, enhancing the reader's experience. A simile, on the other hand, is a figure of speech that compares two different things using "like" or "as," drawing a parallel to illustrate a point or create a vivid picture.

Hyperbole's distinct quality of exaggeration sets it apart from these other devices, making it a powerful tool in literature to convey strong emotions or highlight particular aspects of a narrative. This is why hyperbole is the correct answer in identifying a literary device characterized by overexaggeration.
