The term “double” is employed in literature with remarkable versatility, serving both concrete and abstract purposes. In some texts, “double” clearly quantifies or describes physical attributes—think of its frequent use in technical passages to depict knots, chains, or specific designs, such as the detailed instructions in Lewis Carroll’s works [1, 2, 3, 4, 5, 6, 7] and its descriptive appearance in architectural features [8]. In other instances, authors adopt “double” to underscore intensification or duality, whether that be in reference to emotions and actions—as seen when indignation provides “double strength” [9] or when heartfelt duplicity is highlighted in moral failings [10, 11]—or as a rhetorical device that invites clever wordplay and layered meaning, a trick exploited by Shakespeare [12, 13] and the Lambs [14]. Thus, the word “double” not only quantifies or identifies paired elements but also enriches narratives through its capacity to suggest multiplicity, contrast, and nuanced interpretation.
