Nevermore is a repeated word in poetry that signals finality, loss, or the end of hope. It is most closely linked to Edgar Allan Poe's The Raven, where the raven's repeated reply turns the word into a refrain and a symbol of grief that cannot be eased.
Poets and readers also use nevermore more broadly to suggest something that is gone for good, with no return or second chance.
More broadly, in poetry, “nevermore” represents the collapse of hope—a linguistic marker that closes emotional doors and emphasizes permanence. Its power lies not only in its meaning, but in its repetition, rhythm, and resonance, which allow a single word to echo far beyond the line in which it appears.
Example
The sea has taken back the pier,
and summer's boats are gone from sight;
the tide keeps whispering in the dark,
"Nevermore" through the night.
