praefationis

Praefationis is the genitive singular form of the Latin noun praefatio, which denotes a preface or foreword. In Latin, praefatio refers to the introductory part of a book or work, often presenting the author’s purpose, scope, and audience, and sometimes including a dedication, a justification, or acknowledgments. The term is used in classical, medieval, and early modern texts to indicate the opening device that frames the main content.

Historically, the praefatio could be an integral part of the work or a separately published front matter. It might set out the author’s aims, explain methodology, or reflect on the work’s inspiration. In late antique and medieval manuscripts, praefationes (plural) were sometimes appended by editors or copyists, offering clarifications or historical context for readers. In printed editions, the praefatio often functions as a formal entry point, guiding readers and signaling scholarly intentions.

In linguistic and textual studies, praefatio is distinguished from related opening sections such as the prooemium or exordium. The prooemium typically emphasizes stylistic or argumentative introduction, while the exordium aims to arouse interest or establish credibility. The praefatio, by contrast, is frequently more personal or programmatic, outlining what the work seeks to accomplish and its intended readership.

Today, praefationis appears mainly in discussions of Latin literature, philology, and manuscript studies as the genitive form used to refer to a specific preface, or to describe the nature and function of prefatory material in historical texts. See also praefatio, prooemium, and prologue.
