The word “plug” appears with remarkable versatility in literature, serving both literal and metaphorical functions. In technical and instructional contexts, it denotes a vital component or stopper—such as a valve faced with rubber that controls water flow [1] or a conical stopper in a pipe which regulates steam pressure [2]—while in narrative literature it shifts to a personified or culturally loaded symbol. It can refer to everyday items like tobacco, as in plug tobacco that characters forget before setting sail [3] or a chewable plug of tobacco enjoyed by a character in a moment of levity [4]. At times, it also adopts a colloquial nuance, used as a synonym for “fellow” or “bloke” [5] or imbued with humorous or ironic overtones in interactions among characters [6]. This broad application across genres demonstrates how a single term can seamlessly traverse the realms of mechanical description, social slang, and narrative detail, enriching the texture and meaning of literary works.
