A hamburger is used as a metaphor to depict the literary structure of any paragraph or report in the hamburger paragraph templates. The topic sentence is the initial section of the paragraph, and it gives the main idea and direction of the paragraph in question. It looks like the top bun of a hamburger. The information and supporting comments in the second portion mimic the filling in a hamburger. The third section is the end of the paragraph, which resembles the bottom bun of a hamburger.
