When a poet wishes to use figurative language he or she will use words that are double in meaning. The poet may use an exaggerated expression or something nonhuman, anthropomorphosize, use the figure of speeches like apostrophe, simile, hyperbole, metaphor, personification, oxymoron, and many others.
These figurative language gives style to the author, creating a more artistic figure in writing that entices reader to actually delve into and know its true identity or interpretation.
