What is the author's style in Drown by Junot Diaz?

Like the setting, the language changes throughout the story collection. The narrator
uses language in the stories about Santo Domingo that a child might use; this language in his reflection of the past are how the readers know that Yunior is telling these stories from a much older and less innocent perspective.

When the stories become journal-like, the language reflects the present in the narrator’s life. Any reflection using this language is immediate and not seen through the lens of a much older narrator.

Lastly, when the narrator is telling his father’s story, the language is much more mature and educated. Here the narrator refers to having been to college, and the language, diction, and sentence structure in these narratives demonstrates this.
