Explanation: Alliteration is a literary device that consists in the repetition of the starting sounds of consecutive words, or words that are close to each other. In the given excerpt from the poem "Silver” by Walter de la Mare, we can see an example of alliteration in the line "By silver reeds in a silver stream" because it repeats the sound "s" in the beginning of the words "silver", "silver" (again) and "stream."
