What does preface mean?
A preface is a short introduction that comes before the main part of a book, speech, essay, or other work. It may explain the author’s purpose, acknowledge sources, or provide context for what follows. As a verb, to “preface” something means to introduce it with a statement or explanation: a proposal may be prefaced with remarks about a problem, and a performance may be prefaced by a brief comment. The word is formal and especially common in written publishing, where a preface is normally a separate introductory section rather than part of the main text. It differs from a preamble mainly in typical context: a preface usually introduces a literary or informational work, while a preamble often introduces a document, speech, or proceeding. The term also carries a mild implication of preparation and explanation, helping readers understand how to approach what follows.

Where does preface come from?
The word comes through Old French from Latin praefatio, a noun meaning “a statement made beforehand” or “introduction,” formed from praefari, “to speak before.” The Latin root combines prae-, meaning “before,” with fari, “to speak.” The same root underlies related English words such as preamble and preambulate, while prefatory preserves the idea of something serving as an introduction.
