The word close serves multiple functions in literature. It denotes physical proximity, as characters lean together, move side by side, or encounter elements in their immediate environment (e.g., [1], [2], [3], [4]). It also marks the conclusion of events or actions, suggesting an ending or finality in a narrative, whether it be the termination of a conversation or a session (e.g., [5], [6], [7]). Moreover, close conveys intimacy in human relationships—highlighting bonds that are both emotional and physical (e.g., [8], [9], [10])—and even emerges in abstract notions, describing a tight correlation between ideas or concepts (e.g., [11], [12]).
