Alliteration is the repetition of the same sound at the beginning of a group of words. Line 6 is "<em>Late spring sky,</em> Ms. Marcus says, <em>Almost summer sky.</em>" The /s/ sound is repeated fives times at the beginning of the words in this line of poetry.
Part B: It sounds soothing and peaceful.
The /s/ sound is a soothing and peaceful sound. Even the words soothing and peaceful have the /s/ sound. It creates a soothing a peaceful mood just like the long days at the end of spring and beginning of summer.
These lines are taken from "The Lake Isle of Innisfree" by William Butler Yeats. The theme of these lines is related to the peace. The speaker might be feeling trapped, bussy, sad and that is the reason why his motivation in life is to achieve some peacefulness. So we can say that the main theme is: Peace.
