Subplot The secondary action of a story, complete and interesting in its own right, that reinforces or contrasts with the main plot. There may be more than one subplot, and sometimes as many as three, four, or even more, running through a piece of fiction. Subplots are generally either analogous to the main plot, thereby enhancing our understanding of it, or extraneous to the main plot, to provide relief from it. See also plot.
