Hyperbole

Hyperbole
Definition: A hyperbole is a literary device where the author uses specific words and phrases that exaggerate and overemphasize the main point of the statement in order to produce a grander, more noticeable effect. The purpose of hyperbole is to create a larger-than-life effect and overly stress a specific point.
Example: "I was helpless. I did not know what in the world to do. I was quaking from head to foot, and could have hung my hat on my eyes, they stuck out so far.” (Mark Twain)
