leitmotif

This term describes a recurring element that acts as a psychological or narrative anchor, creating a subconscious link between a specific motif and a character or concept. In music, it functions as a sonic signature that evolves alongside the plot, while in literature, it serves as a symbolic thread that weaves disparate scenes together. As a loanword from German, it retains a specialized connotation of structural unity. It is distinct from a general theme in that it is a specific, identifiable fragment—a short melody or a particular image—rather than a broad abstract concept.
