The word “et” functions primarily as the simple coordinating conjunction “and,” yet its literary use spans a remarkable range of contexts and languages. In scholarly texts such as lexicons and historical works (e.g., [1], [2], [3]), “et” not only connects definitions, events, or lists of authors (as in “et al.”) but also underscores relationships between concepts. In narrative literature and dramatic dialogue—from Victor Hugo’s evocative couplets ([4]) to Shakespeare’s famous exclamation “Et tu Brute?” ([5])—“et” operates as a bridge joining ideas, actions, and characters, subtly enhancing rhythm and meaning. Its ubiquitous presence even in multilingual settings (see examples [6], [7], and [8]) highlights its enduring role as a fundamental tool for clarity and cohesion in literature.
