Coach Lubbock, filling in for the regular teacher, is reading Shakespeare to the class: "But soft. What light through yonder window breaks? It is the Ea . . ." A student raises his hand, asking if the Coach could explain what that means. Coach replies, "Well, it's an analogy, wherein Shakespeare likens the presence of Juliet to that of the rising sun." Actually, it's a metaphor, the figure of speech in which the speaker describes Juliet as being the rising sun. An analogy compares two things that are different, but similar in some way, in order to explain something.
