In literature, the isolated letter “c” frequently appears as a versatile shorthand or indexing symbol that assumes multiple functions depending on context. In historical and grammatical texts, for example, “c.” is often used to indicate a chapter, section, or location within a work—as seen in Edward Gibbon’s histories ([1], [2], [3]) and in George Martin Lane’s grammars ([4], [5], [6]). In other cases, “C” serves as a designation within classifications or lists, such as in Thomas Jefferson’s documents, where it appears alongside other abbreviated forms to group related items ([7], [8], [9]). Additionally, “c” may denote technical terms or serve as part of proper names and initials, as observed in contexts ranging from anatomical descriptions in Aesop’s fables ([10]) to the naming of military figures ([11]). Thus, through its various appearances, the letter “c” exemplifies the use of minimal notation to convey broad, context-dependent meanings in literary and scholarly works.
