                                                                                          patti (29325)
                                                            
                          
                          
                                                          Metonymy is a figure of speech. It can be used in poetry, but is not a poetic device and is not limited to poetry. It is like a metaphor, except the words are associated rather than a comparison. A very common example is the use of "Washington" to mean "the U.S. government."
