This document defines and provides examples of different types of figures of speech used in poetry. It begins by defining a figure of speech as any deviation from common language usage to achieve special meaning or effect. Some common figures of speech are then defined: similes make comparisons using "like" or "as"; metaphors imply comparisons without using "like" or "as"; metonymy associates one thing with another it is closely related to; synecdoche uses a part to represent the whole or vice versa; and personification attributes human characteristics to non-human things. The document emphasizes that figures of speech give language in poetry an original and dense quality.
