CORE DEFINITION

Chekhov's Gun (Russian: Чеховское ружьё), also known as Chekhov's rule, is a narrative technique that states that every element mentioned in a story must appear later, otherwise it is unnecessary to mention it. This technique is common in drama. It became known because the Russian novelist Anton Chekhov mentioned it multiple times in his letters.

Dramatic/narrative principle: if a gun is hung on the wall in the first act, it must be fired in the third; conversely, irrelevant elements should not appear. The mechanism is to maintain narrative economy and suspense through 'necessary to present, present to be useful'.
