What is ironic about Mr Avery's allusion to the Rosetta Stone How does Scout show that she does not know Mr Avery's purpose for using this allusion?

Mr. Avery's allusion to the Rosetta Stone is ironic because, while the Rosetta Stone was key to deciphering ancient languages, Mr. Avery uses it in a context that confuses Scout rather than enlightening her. Scout's lack of understanding is evident when she believes that Mr. Avery is simply referring to the stone's physical characteristics rather than recognizing its historical significance. This highlights her innocence and the gap between adult knowledge and a child's perspective.
