The letter “e” serves a variety of functions in literature, acting not only as a basic component of language but also as a marker in scholarly, formal, and creative contexts. In historical and legal texts, “e” can be found as part of classical phrases (as in [1]), whereas in narrative literature it appears in stylized abbreviations and indexing, like the section labels “1.E.3.” and “1.E.8.” ([2], [3]). Moreover, it is employed in editorial and explanatory devices—for example, functioning within “i.e.” to introduce clarifications ([4])—and in theatrical contractions such as “E’en so” ([5]). The versatility of “e” is further highlighted in its cross-linguistic appearances, from its role in Italian verses by Dante ([6], [7]) to its presence in modern contexts like “e-book” references ([8]). Thus, in its many guises, “e” embodies both the elemental and the elaborate within literary expression.
