In this poem, the author employs foreshadowing. Foreshadowing refers to a literary device in which a writer gives the reader a hint of what is to come next in the story. In this example, Poe talks about Annabel Lee, and he tells us the angels in heaven were jealous of the love the lovers felt for each other. He also tells us that Annabel Lee received a chilling wind. These hints suggest that Annabel Lee will die. The effect of this foreshadowing is that it allows suspense to be built in the mind of the reader, pulling him deeper into the story.
