Hyperbole comes from the Greek word "huperbole," which means "to throw above." It is also known as "auxesis" in rhetoric, which comes from the Greek word for "growth."
Definition-
Hyperbole is a persuasive literary device used by an author or speaker to represent a sentence excessively like an overstatement in order to enhance its effect and bedazzle the reader with the fine feast of his poem, which the reader does not want to end.
How should it be used?
Hyperbole can be employed by selecting an image that would help to use it and then asking yourself which elements of the image are most informative. Compile a list of illustrative examples and use the one which is most suitable and goes with the flow of the sentence.
Here are some examples of hyperbole-
In this sentence it doesn’t mean that the person will literally eat a horse but it shows that the person is very hungry.
In this sentence it doesn’t mean that the person died because he was embarrassed but it means that he is feeling very embarrassed.
In this sentence it doesn’t mean that she is 1000 or more years old like the hills but it means that she is an aged person.
In this sentence it does not mean that the person has actually seen that movie a hundred times but it means that he has seen that movie a number of times.
Conclusion
Hyperbole is a common literary device and figure of speech used in storytelling.
The purpose of hyperbole is to emphasize the poem rather than to deceive the reader.
