In literature, the word "jock" is employed as a familiar, often vernacular marker that denotes a certain rugged, down-to-earth character, frequently with a Scottish or working-class flavor. Authors use it to both individualize characters—as a nickname that suggests informality and tradition—and to invoke folkloric or heroic imagery, as seen when a character is referred to as "Jock o' Nottingham" or even "Black Jock" ([1], [2], [3]). At times, it functions purely as a colloquial address in dialogue, imbuing the conversation with a sense of camaraderie or blunt realism ([4], [5]), while in other contexts it is used metaphorically to attach a distinctive, almost mythic personality to the character, reinforcing their role within the narrative ([6], [7], [8]).
