Marc Twain uses the technique symbolism to make the Mississippi River seem like freedom from Society. "Rivers are roads that move" this quote indicates to us that the Mississippi River is the open road for this boy Huck. The river represents freedom and easiness. "The raft was like freedom, not being' all crumpled up elsewhere," the raft had no need for restrictions of the civilized rules. The effect of using this technique is to connect the book with the reader.
Another technique used by Marc Twain
is a simile. "His hat was laying on the floor--an old black slouch with the top caved in, like a lid”. The effect of using this technique gives us a image in our head that there is a hat on a floor. This is also another technique called imagery; this gives the effect of an image from the description that we see in our head.
Metaphor is another technique used. "The widow... called me a poor lost lamb". This is a quote that compares the widow to a lost lamb. "There warn't no color in his face, where his face showed; it was white; not like another man's white, but a white to make a body sick, a white to make a body's flesh crawl--a tree-toad white, a fish-belly White." the effect of using metaphors is that it aims to create imagery so that the reader may visualize the connection between two objects or things when they are not.
Onomatopoeia is also another technique used throughout the book. “Well, after a long time I heard the clock away off in the town go boom-boom-boom—twelve licks; and all still again-stiller than ever”. The effect of onomatopoeia is that it creates a harsh tone. It is a sound, but used language wise. The reader will understand the meaning of the text more. An ellipsis is also found in this quote. The effect using this indicates that there is a pause in the text or an unfinished thought.
