* Chekhov's gun: This refers specifically to an object introduced early in a story that later becomes significant to the plot. While not always directly revealing character or setting, its presence foreshadows important events, which often illuminates those aspects.
* Symbol: This is a broader term that encompasses objects (and other elements) that represent something beyond their literal meaning. Symbols can reveal aspects of character (e.g., a worn teddy bear representing a character's clinging to childhood innocence) or setting (e.g., a wilting flower representing the decay of a community).
* Props: This term is more commonly used in theatre and film, but it can be applied to literature. Props are objects used to enhance the setting or support the action, often indirectly revealing aspects of character or place.
* Setting details/details of setting: This is a more straightforward description but it correctly identifies the objects as playing a role in establishing the context.
* Narrative artifacts/Storytelling artifacts: This phrase offers a broader approach, including any object contributing to the narrative's impact and the reader's understanding.
The best term to use depends on the specific role the object plays in the story. If the object's importance is primarily its foreshadowing of future events, "Chekhov's gun" is appropriate. If it carries a deeper, symbolic meaning, "symbol" is better. If it's just a part of the setting, "setting details" is sufficient.
