What does the author's purpose encompass in writing?

The author's purpose in writing encompasses the intended intention for writing, which means it refers to the reason why the author has chosen to write a particular piece. This purpose can vary widely; it may aim to inform, entertain, persuade, or express emotions. Understanding the author's intention helps readers grasp the overall message and perspective of the writing.

Focusing solely on narrative styles or persuasive writing limits the understanding of an author’s purpose. An author can write narratively, descriptively, or persuasively, among other styles, to fulfill their intention, but their purpose is broader than just the style employed. Additionally, considering only the format and medium overlooks the essence of why the writing was created, as the purpose is more about the message rather than how it is presented. Thus, focusing on the intended intention encapsulates the full scope of an author's purpose, making it the correct answer.
