What English term, derived from the Latin for "to speak," refers to a book's introduction?

The term "preface" is the correct answer because it originates from the Latin word "praefatio," which means "to speak beforehand." A preface serves as an introduction to a book, written by the author or editor, where they can share insights about the book's creation, its purpose, or acknowledgments. It sets the stage for the content that follows and provides the reader with context.

While a foreword is also an introductory section, it is typically written by someone other than the author and often speaks to the author's credibility or the book's importance. A prologue is generally found in works of fiction and serves as an introduction to the story itself, establishing setting or background information for the narrative. An appendix, on the other hand, contains supplementary material at the end of a book, such as additional data or resources, and is not related to the introduction.
