The term “interchange” manifests in literature as a versatile metaphor for varied forms of mutual exchange. It can capture the instantaneous swapping of ideas or onto the silent trade of glances and sentiments, as when characters exchange a few well-chosen words that hint at hidden depths ([1],[2]). In other instances, it illustrates the fluidity of time and space—a shifting dance of concepts where place and era seem to trade roles seamlessly ([3]). At times, it even encapsulates the philosophical or emotional reciprocity essential to personal identity and relationships, as seen in accounts where profound, almost alchemical exchanges of sympathy and thought occur ([4],[5]). In each usage the word not only denotes a simple act of giving and receiving but also the transformative potential imbued within every subtle or overt communication.
