1. "The sun stepped slowly"** (This is a more subtle example where the "s" sound is repeated within the words.)
2. "Sometimes she would stop suddenly" (Similar to the first example, the repetition of the "s" sound emphasizes her movement.)
3. "Looking like little lamps" (This example is more clear and emphasizes the visual image of the marigolds)
4. "Through the thick twilight" (This instance, while less prominent than others, adds a sense of density and atmosphere to the description.)
It's important to remember that alliteration isn't always used for its sound effect alone. Often, it serves a purpose in enriching the meaning and imagery of the text.
