Final answer:
A flashback is a literary device that interrupts the narrative to relate events from the past. It provides background information and is essential for nonlinear narratives which don't follow a chronological order. Clear transitions help guide the reader through different timelines.
Step-by-step explanation:
The literary device employed when a narrative is interrupted to recount events from an earlier time is known as a flashback. This device is used to provide background information on a character or event that is central to the current storyline. An example of this can be seen in "An Occurrence at Owl Creek Bridge" by Ambrose Bierce, where the story shifts back in time to share how the main character, Farquhar, ended up on the bridge facing execution.
A nonlinear narrative may often utilize flashbacks or vignettes to weave a story that does not follow a straightforward chronological progression. This technique is particularly effective in narratives dealing with trauma or complex character development, but it requires clear communication to the reader when and why the time shifts are happening. The writer can signal these shifts through time-stamps, dates, symbolic imagery, or even through tone and voice changes.
Another aspect to consider in storytelling is the order of events. Most personal narratives follow a chronological order. However, experimenting with different structures such as flashbacks or thematic anecdotes can create engagement and build tension, leading to a more compelling climax. Strategic use of transitions is crucial in guiding the reader through these time jumps, ensuring a smooth narrative flow.
