Here's why:
* Focus on Emotion and Personal Experience: The poem explores the speaker's internal thoughts and feelings as they contemplate the snowy woods and their own journey.
* Lyrical Language: Frost uses vivid imagery, evocative language, and a musical rhythm to create a sense of beauty and contemplation.
* Focus on the Speaker's Voice: The poem is narrated in the first person, focusing on the speaker's subjective experience.
* Structure: While the poem has a clear structure, with its four stanzas of four lines each, the focus is on the emotional impact rather than a narrative structure.
While "Stopping by Woods on a Snowy Evening" is a lyric poem, it can also be categorized as a nature poem due to its focus on the natural world and its influence on the speaker's thoughts and feelings.
