How is the text influenced by having the story told through the eyes of the main character, Huck Finn, a twelve-year-old, unschooled, mischievous boy?

The Adventures of Huckleberry Finn is told from the first person narrative perspective. Being told from a first person perspective already greatly limits the reader's knowledge of events and people. We only know what the narrator knows and feels. Any other information from other people has to be told to the narrator. Additionally, Huck Finn is the story's narrator, and he is a young and lightly educated individual. This affects how he talks, and Twain does a nice job of using dialect to further develop Huck and other characters. Having the narrator be a young Huck also affects other parts of the story as well. We know that Huck is a young, unschooled, mischievous boy, so we know his interpretations of events need to be taken with a "grain of salt," so to speak. He's a bit unreliable because of who he is. This doesn't make him a bad narrator, and it also doesn't mean he's not narrating the truth. In fact, it seems Huck is quite an honest narrator, and that (coupled with his youth) makes him an endearing narrator and character.
