Flash Fiction, in short, is a fiction of extreme brevity. It can range from a few words to a thousand (but usually doesn’t go over a thousand words). It has many terms: microfiction, sudden fiction, short fiction, postcard fiction, or short short story. It has a history that has goes back to Aesop’s Fables and has been used often by many authors like Ernest Hemmingway. There are also exact word count flash fictions such as: the Drabble or Nanofiction (about 100 words in length) 55 fiction and the 69er.*
The key to flash fiction is to create a complete story in as short as time as possible, so conciseness is king here, creating flash fiction is an excellent way to learn this delicate technique. Some people do this by choosing a topic that evokes strong emotion and use that to drive their point home, while others rely on universal knowledge (like ice is cold and loss is sad).
The best way to approach flash fiction is to imagine it as one scene or moment in time, which then you come in with your “camera” and take a snap shot. You then convert that picture into words that stand a testament to your picture for all eternity. So don’t over think or complicate it with too many details, just come up with an idea and write it.
