Two other adjectives which seem pertinent to the mood of Edgar Allan Poe's "The Raven" include the words "weary" and "lost."
Once upon a midnight dreary, while I pondered, weak and weary...
The narrator is both tired and weak from his long, sleepless nights following the death of his deceased loved one. He spends the nights reading instead, trying to relieve his mind of his constant sorrow.
From my books surcease of sorrow—sorrow for the lost Lenore.
The word "lost" has a double meaning here. Lenore has died, and the loss of her is overwhelming to him. Additionally, the narrator is now lost himself: He does not know what to do with himself without his loving companion.
The mood of the speaker in Edgar Allen Poe's poem "The Raven" is one of weariness and bereavement. The whole room is described to resemble an undertaker's parlor, with colors of black, grey and purple - although the funishings and soft furnishings are flush. There are drapes, cushions, a sofa and latticed windows. It is possible that the weakness the poet describes is symptomatic of a person feeling too bereft to eat, sleep or exercise properly. In other words, their helath is failing. It is also possible that the visions of the talking raven are brought on by lack of sleep, or the drowsiness of deep sorrow, where the dream world blurs with reality. The door can then be seen as a portal into another world.
He uses two adjectives in the first couple of verses to describe the day or the time: dreary and bleak. I think these each reflect his mood as well because they demonstrate his weariness and hopelessness he seems to be feeling.
In the very first line, the two adjectives he uses to describe himself are weak and weary. The poem seems to demonstrate that he has been mourning the loss of a woman named "Lenore". Sometimes grief can truly exhaust a person. Thus, it would completely fit the descriptors of weak and weary.
