What happens in Edgar Allan Poe’s poem “The Raven”?

In Edgar Allan Poe’s famous 1845 poem, "The Raven," a grieving student sits alone in his chamber on a "midnight dreary" while mourning his lost love, Lenore.12

A raven suddenly appears and enters the room, perching above the student's door. The bird possesses the ability to speak, though it utters only the single, haunting word: "Nevermore". As the student laments his loss, he asks the bird a series of questions, to which the raven consistently replies with the same refrain. The bird’s insistent repetition becomes an increasingly harrowing response to the student's own internal fears and longing, effectively trapping him in his cycle of grief.12

The poem is a hallmark of American Gothic literature, noted for its complex structure and hypnotic, melancholy tone.2
