Final answer:
Mark Twain's The Adventures of Huckleberry Finn breaks away from romanticism through its use of literary realism, extensive dialogue, and depiction of the river and nature's connection to society.
Step-by-step explanation:
Mark Twain's The Adventures of Huckleberry Finn can be considered a clear break from the formality of romanticism in several ways. Firstly, Twain sought realism in his works, including Huckleberry Finn, which is a characteristic of literary realism. This means that Twain aimed to portray social realities that required reform, rather than romanticizing or idealizing them. Secondly, Twain used dialogue extensively in his novel to advance the plot, define the conflict, and establish authenticity for the readers. Lastly, Twain's portrayal of the river in Huckleberry Finn, although initially appearing idyllic, demonstrates that it is inextricably linked to the social world on the shore, challenging the notion of nature as a privileged and uncontaminated space.
