What is the most plausible theme in the raven

The most plausible theme in "The Raven" is the sadness that the death of the beloved causes.

Explanation:

The Raven is a narrative poem about a man tormented by the memories of a woman named Leonora. One night he is visited by a talking crow, responsible for revealing some truths to him. Built by resources that bring us back to the style of ultra-romanticism, Corvo translates the idealization of love and women, subjectivism, egocentrism, the conscience of solitude and the dark presence of death through free verse. Technically, the poem is remarkable because of the musicality and the supernatural atmosphere, elements constructed through internal rhymes, phonetic games and exact metric. With obscure interpretations of some verbal expressions, the obsession with death has rarely, in the field of literature, gained a poetic architecture so well delineated, musically structured with so much emotion, originality and beware of versification.
