What is the term for a recurring subject, theme, or idea in a literary work?

The term that refers to a recurring subject, theme, or idea in a literary work is "motif." A motif serves as a significant element that can manifest in various forms throughout the narrative, contributing to the overarching themes and enhancing the richness of the text. By repeating specific motifs, authors can create connections and evoke certain feelings or thoughts in the reader, providing deeper insights into the characters, setting, or emotional landscape of the work.

For example, in a novel that frequently features imagery of darkness and light, these elements can serve as motifs that symbolize broader themes such as good vs. evil or knowledge vs. ignorance. This repetition not only reinforces these themes but also helps to establish a sense of cohesion within the narrative.

While "theme" also pertains to central ideas within a literary work, it differs from a motif in that it is more about the underlying messages or concepts the story conveys rather than the specific elements that appear repeatedly. "Emphasis" generally refers to highlighting certain points, and "node" is not a recognized term in this context, making "motif" the most accurate choice for describing a recurrent subject or idea.
