The term "codicil" has been deployed in literature chiefly as a marker of legal and testamentary nuance, often serving as a pivotal plot device. In nineteenth-century novels like Middlemarch, for example, it appears as an addendum to a will that complicates personal and familial relationships ([1], [2], [3]). Similarly, in The Count of Monte Cristo, the codicil is presented as a document of significant acknowledgment, adding layers to conflicts of loyalties and hidden identities ([4], [5]). Earlier still, in Gargantua and Pantagruel, the word hints at even a more casual reference to a testamentary note, emphasizing its longstanding association with final declarations of intent ([6]). Authors such as Southey and Dickens extend its usage by employing the term to underscore formal bequests or to evoke a sense of decay around such statutory provisions, thereby deepening its symbolic resonance across literary landscapes ([7], [8]).
