I'm going to assume by your one word question that you are referring to the compromise made between Scout and Atticus in Chapter 3 of To Kill a Mockingbird. Scout had had a terrible first day at school after running afoul of her first grade teacher, the inexperienced newcomer, Miss Caroline. Among Miss Caroline's complaints was that Atticus was not a qualified teacher, and she demanded that he stop reading to Scout. Scout decided that it would be best if she quit school; she could learn everything she needed at home, taught by Atticus and Calpurnia, she believed. But Atticus had another idea.
"Do you know what a compromise is?" he asked.
"Bending the law?"
Atticus explained that it was "an agreement reached by mutual concessions." When he proposed that Scout return to school if they both agreed to continue their nightly reading--without Miss Caroline's knowledge--Scout accepted the "bargain."
