Here's why:
* Narrative Poetry: This type of poetry focuses on telling a story, with a clear plot, characters, and setting. It aims to engage the reader emotionally through the unfolding of events.
* "La Belle Dame sans Merci": The poem tells the story of a knight who encounters a beautiful woman and is ultimately lured to his doom. The poem features:
* Plot: The knight's encounter with the woman, his journey, and his final state.
* Characters: The knight and the "Belle Dame" (beautiful lady).
* Setting: An ambiguous, haunting landscape.
While the poem also utilizes elements of ballad poetry, like its use of repetition and its focus on the supernatural, the core of its structure and appeal lies in its narrative structure. The reader is drawn into the knight's story and experiences his feelings of enchantment and ultimate despair.
