The terms "author," "writer," and "narrator" are related but distinct roles within the realm of literature.

An author is the person who creates or originates a written work. They conceive the overall idea, develop the plot, characters, and themes, and are responsible for the creative aspect of the work. The author's role encompasses the entire process of writing and shaping the narrative.

A writer, on the other hand, is a broader term that encompasses anyone who engages in the act of writing. It refers to individuals who produce written content, whether it's fiction, non-fiction, articles, essays, or any other form of written expression. Writers may include authors, journalists, playwrights, poets, and more.

A narrator, on the other hand, is a specific character or voice within a written work who tells the story. The narrator can be a participant in the events (first-person narrator) or an observer (third-person narrator). The narrator provides the perspective through which the story is conveyed, sharing details, thoughts, and emotions to engage the reader and shape their understanding of the narrative.

In summary, an author is the creator of a written work, a writer is someone who engages in writing activities, and a narrator is the character or voice that tells the story within the work.
