The term 'INTRODUCTORY PART' can be defined as the beginning of a book, article, or speech. This term can be broken down into two words: EXORDIUM (8 letters) and PREFACE (7 letters). An EXORDIUM is an introduction that is meant to engage the reader or listener and set the tone for the rest of the work. A PREFACE is a brief introduction that usually includes information about the author's purpose in writing the work. Both of these terms are used to provide context and background information to the reader or listener.
