Define scout?

The narrator of the novel, Jean Louise "Scout" Finch is almost six years old at the time her story begins. A tomboy most frequently clad in overalls, Scout spends much of her time with her older brother Jem and is constantly trying to prove herself his equal. Throughout the book Scout maintains an innocence and an innate sense of right and wrong that makes her the ideal observer of events, even if she doesn't always fully understand them. She naturally questions the injustices she sees instead of accepting them as "the way things are." For instance, she doesn't understand why her aunt makes social distinctions based on "background" when Scout thinks "there's just one kind of folks: Folks." Her independence and outspokenness often get Scout into trouble, however; she is quick to respond to insults with her fists and frequently opens her mouth at inappropriate moments, as when she rudely remarks on the table manners of a guest. By the end of the novel, however, eight-year-old Scout has learned a measure of restraint, primarily through the influence and example of her father Atticus.
