Definitely a novel. 'Huck Finn' offers a rich narrative and complex characters typical of a novel. Mark Twain crafted a compelling story with depth and themes.
Huck Finn isn't a true story. It's a work of fiction that Twain crafted to explore various themes and social issues of the time through the adventures of the characters.
Sure is. Huck Finn is a picaresque novel because it showcases Huck's adventures, his growth and experiences along the way, and the unconventional and often humorous situations he finds himself in.
