Answer:
The word choice in a poem can greatly impact the tone and overall meaning conveyed to the reader. In this case, the poet's use of specific images such as migrations, sand, and the tail of a comet to describe dreams can have various effects on the tone of the poem.
1. Migrations: The image of migrations suggests movement, change, and a sense of journey. It can evoke a tone of exploration, adventure, and the pursuit of new experiences. It may also imply a sense of restlessness or a desire for something beyond the current state.
2. Sand: The image of sand can have multiple connotations. It can symbolize the passing of time, as sand slips through an hourglass. It can also represent fragility, as sand can easily be blown away by the wind. This choice of imagery can create a tone of transience, impermanence, and the fleeting nature of dreams.
3. Tail of a comet: The image of the tail of a comet suggests something rare, extraordinary, and ephemeral. Comets are often associated with celestial events and are known for their dazzling displays. This choice of imagery can evoke a tone of wonder, awe, and the idea that dreams are extraordinary and magical occurrences.
Overall, the poet's word choice impacts the tone of the poem by creating a sense of movement, transience, and wonder. It conveys the idea that dreams are dynamic, fleeting, and hold a certain enchantment. The specific images chosen help to shape the emotional and imaginative response of the reader, influencing the overall tone of the poem.
