What role does a "protagonist" play in a narrative?

The role of a protagonist in a narrative is that of the main character who actively engages with and encounters challenges or conflict throughout the story. This character is central to the plot and can be seen as the driving force of the narrative. The protagonist typically undergoes significant development or change, often facing obstacles that test their values, beliefs, or skills. This journey is crucial for the story's progression, as it allows readers to invest emotionally in the protagonist's experiences and growth.

While there are other important characters in a narrative, such as antagonists who create conflict or minor characters who provide support, the protagonist is the one whose journey and transformation usually highlight the central themes and messages of the work. In essence, understanding the protagonist's role helps readers grasp the main storyline and the overarching emotional or moral exploration of the narrative.
