Appendices or Appendixes? Clarifying Usage

When it comes to writing one of the most common questions that often arises is whether to use appendices or appendixes. Both terms are used to refer to supplementary materials added at the end of a document, research paper, or book.

But, what’s the difference between these two words, and which one is correct in a particular context. Let’s explore the usage of appendices and appendixes to clarify the confusion.

What is an Appendix?

An appendix is a section that is added at the end of a book, report, or other written work typically to provide additional details, explanations, or references that are supplementary to the main text. The word appendix comes from the Latin word appendere, meaning “to hang upon,” which perfectly describes the nature of this section an extra part tacked onto the end of the document.

In anatomy, appendix refers to a small pouch-shaped organ attached to the large intestine. The anatomy of appendix has intrigued medical researchers, who have studied its histological structure of appendices to better understand its role. Despite its name, the anatomical appendix is not to be confused with its literary counterpart.

Singular and Plural Forms: Appendices vs. Appendixes

In English, the plural of appendix can be either appendices or appendixes, and both forms are correct. However, the usage depends on the context and sometimes even personal or stylistic preferences.

• Appendices: The word appendices follows the Latin pluralization pattern, which is commonly used for words of Latin origin. This form is typically seen in academic, technical, and scientific writing.

• Appendixes: Appendixes is the standard English pluralization, following English rules for pluralizing nouns by adding “es.” It is widely accepted in general writing, including informal contexts, emails, and other non-technical documents.

For example, when writing a research paper appendices section, you are more likely to use appendices to maintain a formal tone and respect academic conventions. On the other hand, if you’re writing a more casual email or letter, you might use appendixes to sound more natural and conversational.

Examples in Context

Let’s see how both forms of pluralization work in context:

• Appendices: “Please refer to the appendices of this report for additional details on the survey data and methodology.”

• Appendixes: “I’ve attached the appendixes with further information on the topics we discussed in our last meeting.”

In these examples, both words are used correctly, but the first sentence shows a more formal academic tone, while the second is slightly more casual.

When to Use Appendices vs. Appendixes?

When deciding between appendices or appendixes, consider the writing style guide usage you are following. For example, academic papers, such as research papers, usually prefer appendices due to their Latin origin and formal tone.

In contrast, book references or general documents might feel more natural with appendixes. As this form aligns more with the English language’s standard rules of pluralization.

Scenario: Academic Paper

If you’re working on a research paper and need to provide supplementary material, you might write:

“Appendix A contains the raw data, while Appendices B and C provide additional analysis and supplementary charts.”

Here, the use of Appendices sounds more professional and aligns with the English pluralization rules for academic writing.

Scenario: Email Communication

Let’s say you’re emailing a colleague about some additional sections to a report:

“Hi Sarah,

I’ve sent over the revised report, and the appendixes are attached with further details on the project timeline and budget breakdown.”

In this case, appendixes works perfectly, as the tone is more informal, and the pluralization follows standard English rules.

The Latin Pluralization Pattern vs. English Pluralization Rules

The word appendix is a great example of how English can draw from both Latin pluralization patterns and English pluralization rules. Latin often forms plurals by adding -ices to words ending in -ix, like appendix becoming appendices. In contrast, English typically adds -es to form plurals, resulting in appendixes.

This is where things can get tricky, and writers need to decide which form best suits their context. While both appendices and appendixes are correct, understanding the nuances. It can help you choose the right word based on the tone and formality of your writing.

For example, a book reference might say:

“For a deeper dive into the methodology, please see the appendices, where we’ve included full survey questions and responses.”

Here, appendices is appropriate because it’s part of an academic or formal text, consistent with writing style guide usage that suggests following the Latin pluralization pattern.

Some writers may use appendixes for clarity and simplicity, while others adhere strictly to the Latin-based appendices. The choice can sometimes seem minor but for formal or academic writing, it’s always a good idea to check your writing style guide usage.

For example, academic disciplines that focus on the anatomical organ names (like in medicine or biology) might discuss the histological structure of appendices in relation to the small pouch-shaped organ in the human body. Here appendices would be the correct form, as it follows scientific and medical writing conventions.
