A person uses a hyperbole, which is an exaggeration, to get a point across. Have you ever heard the phrase I've told you a million times not to do ____(you fill in the blank). The, "I've told you a million times, would be the hyperbole.
Personification is when an author or a person makes an object have person/human like qualities.
An onomatopoeia is a word(s) that describe an object that sounds like the object. For example, if I were to say drip, you might think of water dripping.
Idioms are clichés. They are phrases, such as "he is made of money."
Puns are words that are play-ons. Typically they are used for humor.
