The load-bearing word
In micro-fiction, every word is either pulling its weight or taking up space that another word could use better. This is not a metaphor but a literal constraint: in a 100-word story, a wasted word is one percent of the total, and in a six-word story, a wasted word is one sixth. Developing the habit of reading your micro-fiction with this awareness — asking of each word what it is doing that another word could not do better, or that silence could not do just as well — produces a different relationship to language than longer forms require. The load-bearing word in micro-fiction is usually a verb or a noun: concrete, precise, doing actual work rather than adding atmospheric pressure.
The turn
Micro-fiction needs a turn — the moment when the story pivots and the reader arrives somewhere different from where they started. The turn in a flash story can be a reversal, a revelation, a realization, or a shift in perspective that retroactively changes the meaning of everything that came before. In very short forms, the turn often comes in the last sentence, or the last phrase, or in some cases the last word. Writing toward the turn means knowing, before you begin, what the story's essential movement is: from what to what, and through what specific moment. The turn is not a trick ending; it is the story's destination, the place toward which all the preceding details were already pointing.
White space and implication
White space in micro-fiction — the things the story does not say, the scenes it skips, the explanation it withholds — does as much work as the words on the page. A story that cuts from one moment to a later one implies everything that happened between them, and the reader's imagination fills the gap with something that is, for them, precisely right. This implied content often carries more emotional weight than the actual content would: the scene the reader imagines is more vivid and more affecting than any scene the writer could have written. Learning to trust white space requires accepting that the reader's imagination is a resource you can use rather than a gap you must fill.
Character in a single gesture
The character in micro-fiction cannot be built the way a novel character is built, through accumulated behavior and internal reflection over hundreds of pages. The micro-fiction character must be established through a single gesture, action, or detail that implies the whole person. The art is in choosing the right detail: one that is specific enough to feel true, distinctive enough to distinguish this person from all others, and resonant enough to suggest a history and a psychology without requiring either to be stated. Practice this by writing character-defining details that are not on the expected list for the situation: not the thing the character does that anyone would do, but the thing only this specific person would do, in this specific way, for reasons the reader can infer.
The six-word story as constraint
The six-word story — descended from the probably apocryphal Hemingway “For sale: baby shoes, never worn” — is an extreme case that clarifies the principles of all micro-fiction. At six words, no word can be wasted, no construction can be merely conventional, and the implied content must do nearly all the emotional work. Writing six-word stories is useful as an exercise even for writers who work in longer flash forms: it forces the identification of the single essential thing the story is about and the single most precise way to approach it. A six-word story is not a premise or a tagline; it is a complete narrative movement in miniature, with a before and an after and a change between them.
Revision as excavation
The revision process in micro-fiction is excavation rather than addition: the story is already there, and the work is to remove everything that is not the story. Begin by writing more than you need — a draft that is too long, too explained, too careful about the reader's comfort — and then find the story inside it. Where does the piece become alive? Which sentence carries the most charge? Start the story there. What information does the reader actually need to follow the turn? Keep only that. What are you explaining that the reader can infer? Remove the explanation and leave the implication. What you arrive at after this excavation is the story in its most essential form: the version that is exactly as long as it needs to be and no longer.
