The letter “k” takes on a multifaceted role in literature, serving various purposes depending on context. In Franz Kafka’s works, for example, “K.” functions as an enigmatic identifier for the protagonist—a device that imbues the narrative with a sense of ambiguity and universality [1], [2], [3], [4], [5], [6], [7], [8], [9], [10]. By contrast, in technical treatises such as José Raúl Capablanca’s Chess Fundamentals, “K” is part of the specialized notation system used to record moves (e.g., “K - Q 3” [11], “K - K 2” [12]) and to denote specific game pieces [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24]. Furthermore, “K” appears in historical and scholarly texts both as an initial in abbreviated names or titles—often indicating a person of note (as seen in titles like K.C.B. or in entries like “K. D. Erskine” [25], [26], [27], [28], [29], [30], [31])—and as a linguistic element or transliteration in texts ranging from ancient manuscripts and folklore [32], [33], [34], [35], [36], [37], [38], [39], [40], [41] to treatises on mathematics, logic, and culture [42], [43], [44], [45], [46]. Thus, “k” evolves from a mere alphabetical character into a symbol rich with narrative, technical, and historical significance.
