Question

How does the hyphen and font help to advance the theme?

Answer 1

The pause made by the hyphen gives a sense of hanging. It means to invite the readers to read and think at a certain pace. As a result, voice is able to make the up and down to the emotional effect and in the same time infiltrate the readers with a continuous meaning transfer.
Any type of font does not change the meaning of the words. But the font changing in the middle of a written will change the focus and the emphasis. Here, the poet uses capitalized word for all words in the line 25-33 in a row.
