The use of "substitute" in literature is remarkably versatile, functioning not only as a simple replacement for one tangible object with another but also as a metaphor for more abstract or symbolic stand-ins. Authors employ the term to denote a deliberate swap—such as replacing a genuine substance with a lesser one or adopting an alternative method in place of tradition—thereby inviting readers to reflect on authenticity and value ([1], [2], [3]). In some narratives, practical exchanges are detailed, where one item, like a wig or a different means of travel, takes the place of a lost or preferred original ([4], [5]), while in other works, the word extends into the realm of ideas, substituting established rituals or beliefs with modern equivalents or even entirely new constructs ([6], [7], [8]). Furthermore, the concept is harnessed in discussions of language and style, serving to illustrate shifts in meaning or grammatical adjustments ([9]), and in dramatic storytelling, where it encapsulates themes of replacement and transformation within personal relationships and societal roles ([10], [11]).
