What is a critical characteristic of a round character?

A critical characteristic of a round character is that they are complex and develop over time. These characters often possess multiple traits and qualities that make them more realistic and relatable. Unlike flat characters, who might embody a single trait or idea, round characters undergo personal growth or change as the story progresses. This development often reflects the complexities of real human emotions and psychology, allowing readers to engage more deeply with them and see their struggles, motivations, and transformations.

The other options highlight features that do not accurately describe round characters. A one-dimensional character, for instance, lacks depth and does not exhibit the complexity typical of a round character. Characters who do not change throughout the narrative are usually flat or static characters. Finally, characters that serve merely as a foil typically exist to contrast with another character, highlighting their attributes rather than being fully developed individuals themselves. Overall, the ability to evolve and exhibit complexity is what fundamentally defines round characters in literature.
