Chekhov's gun (Chekhov's rifle; Russian: Чеховское ружьё) is a narrative principle that states that every element in a story must be necessary, and irrelevant elements should be removed. For example, if a writer features a gun in a story, there must be a reason for it, such as it being fired some time later in the plot. All elements must eventually come into play at some point in the story. Some authors, such as Hemingway, do not agree with this principle.
The principle is recorded in letters by Anton Chekhov several times, with some variation; it was advice for young playwrights.
In recent years, the term has also taken on the meaning of a plot element that is introduced early in a story, whose significance to the plot does not become clear until later. This meaning is separate from Chekhov's original intention with the principle, which relates to narrative conservation and necessity, rather than plot significance.
