Have you ever been reading a book, newspaper, or research paper and spotted a little note at the end that says “errata”? If so, you might have wondered what it actually means. Maybe you even guessed it had something to do with errors or mistakes. And you’d be right!

In this article, we’re going to explore the word erratum and its plural form. Don’t worry we’ll keep things light, simple, and beginner-friendly. By the end, you’ll know not only what “erratum” means, but also how to use its plural form, “errata,” correctly in everyday situations.

Let’s take a closer look at this interesting word.

What Does “Erratum” Mean?

The word erratum comes from Latin and literally means “a mistake” or “an error.”

In English, it is often used in publishing, writing, or academic contexts to describe a single error found in a printed or published work. If a book had one mistake, such as a misspelled name or a wrong date, that mistake would be called an erratum.

So, in short:

• Erratum = one mistake, often in a printed work.

What Is the Plural of Erratum?

The plural of erratum is errata.

This is because the word follows Latin grammar rules, not the usual English way of adding -s or -es to make plurals. Instead, just like many Latin-origin words in English, the ending changes when you want to talk about more than one.

• Erratum → Errata

So if a book has multiple mistakes, they would be listed as errata.

Why Not “Erratums”?

It might feel natural in English to just add an -s and say “erratums,” but that’s not considered correct in standard usage. Since the word has been borrowed directly from Latin, English speakers usually stick to the original plural form.

This is similar to other Latin-based words:

• datum → data
• medium → media
• bacterium → bacteria

Just like those, erratum turns into errata when there is more than one mistake.

Is “Errata” Singular or Plural?

This is a common question!

• Erratum is singular (one error).
• Errata is plural (two or more errors).

For example:

• “There is one erratum in this book.”
• “The publisher released a list of errata for the textbook.”

However, in modern English, some people sometimes use errata to talk about a single error, though that is technically incorrect. It’s always best to stick with the traditional meaning: erratum = one, errata = many.

Examples in Sentences

Let’s make this crystal clear with practical examples:

• Correct use of erratum:
  • “An erratum was found on page 45 of the report.”
  • “The author issued an erratum for the incorrect date.”
• Correct use of errata:
  • “The journal published a list of errata after printing errors were discovered.”
  • “The teacher pointed out several errata in the old edition of the textbook.”
• Incorrect use (to avoid):
  • “There were many erratums in the book.” ❌

Where Do We See “Errata” in Real Life?

You’ll often come across errata in:

• Academic books and research papers.
• Technical manuals or guides.
• Newspapers or magazines issuing corrections.
• Online publications when they update a mistake.

For example, at the end of a scientific journal article, you might see a note titled “Errata” where the publishers correct small errors that were printed in earlier versions.

A Quick Definition Recap

Let’s summarize everything so far in simple words:

• Erratum = one mistake (singular).
• Errata = more than one mistake (plural).
• Usage: Mostly in books, journals, and formal writing.

Fun Facts About Erratum and Errata

Here are some interesting extras you might enjoy:

1. Latin roots: The word erratum comes from the Latin verb errare, which means to wander or to make a mistake.
2. Old-fashioned feel: Today, you won’t hear people saying “erratum” in casual speech. You’re more likely to hear “typo” or “mistake.” But in publishing, “erratum” and “errata” are still very common.
3. Cousin words: The English word error also comes from the same Latin root. So “error,” “erratum,” and “errata” are all related.
4. Errata sheets: Sometimes, when a book is printed with errors, the publisher includes a small extra page called an “errata sheet” that lists all the corrections.

Comparison With Similar Words

To make things even clearer, let’s compare erratum/errata with some similar words:

• Typo: Usually means a small spelling or typing mistake, often informal. Example: “Oops, I made a typo in that text message.”
• Error: A general word for a mistake in any context, not just writing. Example: “The software showed an error message.”
• Correction: The fixed version of a mistake. Example: “The newspaper printed a correction for yesterday’s error.”

So, while all these words deal with mistakes, erratum/errata are more formal and specific to published works.

How to Remember the Plural Form Easily

If you’re worried about forgetting whether it’s erratum or errata, here are a few easy memory tricks:

1. Think of “data.” Just like datum → data, we have erratum → errata.
2. Remember that -um in Latin words often changes to -a in the plural.
   Examples:
   • curriculum → curricula
   • memorandum → memoranda
   • erratum → errata
3. Link it with the idea that multiple mistakes add up, so you need the longer word errata for more than one.

Common Mistakes to Avoid

When learning new words, it’s easy to mix things up. Here are some pitfalls to watch out for:

• Saying “erratums” instead of errata.
• Using errata when talking about only one mistake.
• Confusing erratum/errata with the casual word “typo.”

Sticking to the correct form will help you sound more natural in formal or academic settings.

Practice Time: Try It Yourself

Let’s do a little practice. Can you guess which form fits in these sentences?

Final Thoughts

The word erratum may sound fancy, but at its core, it’s just a formal way of saying a mistake. Its plural form, errata, means more than one mistake.

Here’s the easy takeaway:

• Use erratum for a single error.
• Use errata for multiple errors.

Now that you know the difference, you can confidently read books, articles, and journals without getting tripped up by these words. And who knows, you might even impress someone by casually dropping “erratum” into a conversation!
