Answer:
The speaker of "The Raven" is a man who is mourning the loss of his beloved, Lenore. He is in a state of deep grief and despair, and the raven mirrors his mental state by constantly repeating the word "Nevermore," reminding him of his loss and driving him to madness. The bird's haunting presence and eerie repetition taps into the speaker's subconscious fears and frustrations, contributing to his mental breakdown. As the speaker spirals deeper into madness, the raven becomes a symbol of his tortured psyche and unrelenting sorrow.
