Final answer:
Repetition in 'To Kill a Mockingbird' is used to emphasize key themes, as seen in the repeated phrase "it's a sin to kill a mockingbird" and the recurring discussions of Boo Radley.
Step-by-step explanation:
An example of repetition in Harper Lee's novel To Kill a Mockingbird is the phrase "it's a sin to kill a mockingbird." This phrase is first introduced by Atticus Finch and later reiterated by Miss Maudie. It symbolizes the idea of preserving innocence and not harming those who do no wrong. Another aspect of repetition within the novel is the recurring discussion of the character Boo Radley. His presence looms throughout the story, creating a sense of mystery and fascination among the children. These repeated elements are used intentionally to emphasize key themes and motifs in the novel.
When reading any work of literature, such as Harper Lee's novel, it's important to be on the lookout for repeated words or phrases, as they often contribute to the work's larger thematic elements and character development.
