Here's why:
* Odes are poems that express praise, admiration, or strong emotion for a specific person, place, or thing. They often have a formal structure and elevated language.
* "The Raven" is a narrative poem, telling the story of a grieving man haunted by a raven. It does not express praise or admiration, but rather focuses on the speaker's descent into madness and despair.
While "The Raven" does use some poetic devices common in odes (like elevated language and repetition), its primary focus is storytelling, not praise.
