Hyperbole is a figure of speech that uses exaggerated statements to create a strong emotional response, though it is not meant to be taken literally. It is commonly used for humor and can be found in poetry and casual speech, where things are described as better or worse than they actually are. Hyperboles provide insight into one's theories of knowledge and understanding of self. Puns are a form of word play that use multiple meanings of words or similar-sounding words for humorous effect, requiring an extensive vocabulary to understand in some cases. They have long been used by comedians and playwrights to create humor.
