Answer:
Wordsworth uses the word "dance" in stanzas 1 and 4 to describe the movement of the daffodils. In stanza 1, the daffodils are "fluttering and dancing in the breeze," while in stanza 4, they are "tossing their heads in sprightly dance." By describing the movement of the daffodils as a dance, Wordsworth suggests that nature is not just a passive backdrop but an active participant in the world. The daffodils are not just objects to be observed; they are living things with their agency and vitality. The word "dance" also connotes joy and celebration, reinforcing the idea that nature is a source of happiness and inspiration.
