In this book i'm reading, I want to know the proper "literary device" name that's used here.
In this chapter it's just a series of letters that someone received, which also tells the story.
From 1 certain person, the first letter ends with:
Jay W. Dudley, Editor
And over time, to show how they have become closer and gotten to know eachother more, and become friends, the end of the letters becomes simpler like
and finally in the end of chapter
I know that repeating the same phrase over and over at end of paragraphs is called alliteration but what would it be called in this case where it is the same but changes.
What other literary devices could be in here?
