Appendix vs. Appendices: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on October 3, 2023
"Appendix" is a supplementary material at the end of a book or document, while "Appendices" is its plural form.

Key Differences

"Appendix" refers to a section at the end of a book or document that provides additional information, which, while not essential to the main text, complements it. This might include tables, charts, raw data, or detailed explanations. In contrast, when a document contains multiple such sections, they are collectively referred to as "Appendices."
The inclusion of an "Appendix" is especially common in academic papers, where authors may want to provide readers with further evidence or in-depth analyses without interrupting the flow of the main content. When there are several of these supplementary sections, differentiating between them becomes necessary. Thus, multiple "Appendices" are usually labeled with letters or numbers for easier reference.
Using the term "Appendix" signifies the presence of a singular supplementary section. For instance, a single survey or a detailed methodology might be provided in an appendix. "Appendices," being plural, suggests the presence of multiple supplementary sections, perhaps various data sets, or distinct methodologies pertaining to different chapters.
It's essential for writers and readers alike to recognize the distinction between "Appendix" and "Appendices." While both offer extra content that supplements the primary document, understanding whether there's one or multiple additional sections can shape the reader's approach to the material. For instance, a document might mention "see Appendix A," indicating a specific section among several "Appendices."
