Figures of speech are used to produce special effects through creative language. There are several types of figures of speech including similes, metaphors, hyperboles, irony/sarcasm, and metonymy. Similes explicitly compare two things using like or as, metaphors make imaginative comparisons, and hyperboles exaggerate for effect. Irony and sarcasm imply the opposite of what is said, while metonymy represents one thing by something closely associated with it.
