What does the term "antithesis" specifically involve in literary works?

Antithesis specifically involves contrasting opposing ideas within a literary work. This rhetorical device is employed to create a clear distinction between two contrasting concepts, thereby highlighting their differences. It allows writers to emphasize a particular point or create a dramatic effect by juxtaposing contradictory ideas in a balanced way.

For example, phrases like "to err is human; to forgive, divine" showcase antithesis by directly contrasting human fallibility with the noble quality of forgiveness. This contrast not only enriches the text but also provokes thought and deepens the reader’s understanding of the themes being explored.

The other options do not accurately capture the essence of antithesis. While combining similar ideas refers to a unifying technique, reiterating a concept involves repetition rather than contrast. Displaying character traits is more related to character development and does not pertain directly to the concept of opposing ideas.
