audience. knowing WHO the author is writing for often gives you better context and understanding of their purpose; for example, if you take into account like children's books, you see that a lot of them have specific morals or lessons behind them to help a child develop good character. if you misinterpreted a children's book to be for an adult, you wouldn't understand the author's purpose as well because you're trying to figure out how a lesson for children could apply to an adult.
