Step-by-step explanation:
Definition of a Short Story
An imaginative prose narrative designed to create a single impression and short enough to be read in one sitting is known as a short story. Unlike a novel, which may span across a wide array of events, locations, and characters over a more extended period, a short story has a compact narrative that focuses on fewer characters and a shorter time span. The plot of a short story is structured around a central climax or turning point which often leads to an unexpected direction or twist at the end, thereby encapsulating the theme and provoking reflection.
Short stories are a type of fictional prose that, despite sometimes crossing the length of a short novel, are distinguishable from novels and novellas based on their tight narrative focus and the specific impact they aim to have on the reader. Prose is organized in paragraphs and sentences, and within the domain of fiction, it includes types such as short stories, novellas, and novels. A short story's organizational scheme is vital, often with a linear narrative organized into sections or chapters, but always keeping the story concise enough for a single sitting read.
In contrast, plays are generally written in dialogue and stage directions, and poems focus on expression through verse and rhythm rather than narrative prose. As for the novella, it lies in between the short story and the novel regarding length and depth of narrative.
