There are several common storytelling structures that writers use to create compelling narratives. Here are some of the most popular:

1. Three-Act Structure

The three-act structure is a classic storytelling model that divides a narrative into three parts: the setup, the confrontation, and the resolution. This structure is often used in film and theater, but it can be adapted for other forms of storytelling as well.

2. Hero's Journey

The hero's journey is a narrative structure popularized by Joseph Campbell in his book "The Hero with a Thousand Faces." This structure follows a hero as they embark on a journey, face challenges and trials, and ultimately emerge transformed.

3. In Medias Res

In medias res is a Latin phrase that means "in the middle of things." This structure begins in the middle of a story, often with a dramatic event, and then goes back to fill in the earlier events through flashbacks and exposition.

4. Epistolary Narrative

An epistolary narrative is a story told through letters or other written correspondence. This structure can offer insights into characters' inner thoughts and feelings, and can also create a sense of realism and authenticity.

5. Nonlinear Narrative

A nonlinear narrative is a story that does not follow a linear timeline. Instead, it may jump back and forth in time, or present events out of order. This structure can create suspense and intrigue, as well as offer unique perspectives on the story.

These are just a few of the many storytelling structures that writers use to craft their narratives. By experimenting with different structures, writers can create stories that are engaging, thought-provoking, and entertaining.
