A linear structure follows a chronological order, where events unfold in a sequential manner from beginning to end. On the other hand, a nonlinear structure presents events in a non-sequential order, jumping back and forth in time or presenting multiple perspectives. An author might choose to use a nonlinear structure to create suspense, add complexity to the plot, or challenge the reader to piece together the story in a non-traditional way. This can make the narrative more engaging and intriguing for the reader, as they are required to actively engage with the text to understand the story fully.
