What is a minor character?

One minor character in a story could be a bartender who only appears in a few scenes but has a significant impact on the main characters. This bartender may be wise and insightful, offering advice or support to the protagonists during key moments in the plot. Despite their limited role in the story, the bartender's actions and words can help drive the narrative forward and shape the development of the main characters. This character may also serve as a symbol of the larger themes or conflicts of the story, as their interactions with the protagonists illuminate important aspects of the plot. Ultimately, even though they may not be the central focus of the story, the bartender plays a crucial role in shaping the overall narrative and contributing to the depth and richness of the story world.
