How does harper lee developed the symbolic meaning of the mockingbird throughout the novel?

Mockingbird symbolizes innocence and kindness, traits which Lee portrays through the characters of Tom Robinson and Boo Radley.

Explanation:

To Kill a Mockingbird is Harper Lee's novel which deals with an innocent man's trial and conviction, thus portraying the racial inequality present at the time it was written.

Mockingbird is a symbol that represents innocence and kindness, virtues primarily seen in the characters of Tom Robinson and Boo Radley. Tom Robinson is accused of raping Mayella Ewell, and, although innocent, is proved guilty because he is a black man. This results in Tom's escape attempt and his death. Scout and Jem's father defends Tom in a courtroom, and through his case, children learn that 'it is a sin to kill a mockingbird'.

In addition, Boo Radley is presented as a dangerous man at the beginning of the book. Rumor has it that he is locked up in his house and is not allowed to leave it, because he did something terrible in the past. Boo, however, saves Jem and Scout when Mr. Ewell attacks them. People of Maycomb, again, misjudged a person based on their prejudices and gossip.
