Which term is used to describe a significant struggle faced by a protagonist?

The term "conflict" is used to describe a significant struggle faced by a protagonist because it encapsulates the central tension or problem that drives the narrative. Conflict can take many forms, including internal struggles within the character (psychological conflict) and external struggles with other characters, society, or nature. This struggle is crucial as it propels the story forward, shapes the character's journey, and ultimately leads to growth or change.

In contrast, "plot" refers to the sequence of events that unfold in a story but does not specifically denote the struggle itself; it encompasses the overall structure of the narrative. "Theme" pertains to the underlying message or moral of the story, highlighting what the author aims to convey about life or human nature. "Character development" focuses on how characters evolve throughout the story, influenced by the conflicts they face, but does not explicitly suggest the struggles themselves. Thus, "conflict" stands out as the most accurate term for describing the significant struggles faced by protagonists.
