In these two stanzas, Wordsworth uses the word "dance" to illustrate the joyous, free-spirited nature of the daffodils. The waves beside the daffodils are described as "dancing", which emphasizes their unbridled happiness and merriment. Additionally, Wordsworth compares his heart to the daffodils, stating that it "dances with the daffodils". This is a metaphor which implies that his heart is filled with the same joy and energy as the daffodils, and that the beauty of the daffodils has uplifted his spirits. The use of the word "dance" throughout the poem reveals Wordsworth's admiration of the daffodils, and also his desire to feel the same joy and freedom that they embody
