It is a character because Huck has to learn how to deal with it, live on it, “communicate” with it. I havent’ read the book in awhile but if you did you could probably add more examples there. I really hope you read the book, it’s great.

And of course its’ the setting because that’s where they are, etc. And setting influences EVERYTHING.

1. Symbol: An object that has a greater meaning that the intended purpose. For example, the cross in some religions is a symbol for Jesus. Think about it: what did this river represent to Huck?

2. Character: A participant in a story. How did the river participate in the story? Did it have any human characteristics? Did Twain personify the river at all in his writings?

3. Setting: The location of the story (this is the easiest!)

Good luck.
