The Purpose and Usage of et al. in Citations

In academic writing, clarity is key. One tool that aids in concise citations is et al.

But what does it mean? How do we use it correctly in APA, MLA, and Chicago styles? In this blog, we'll explore the purpose and usage of et al. to help writers master citation conventions effectively.

Let's dive in and make citations simpler!

What Do We Understand by et al.?

et al. is a short way to refer to a group of people. In Latin, it means “and others.” When you see it in a citation, it means there are more authors than the ones listed. For example, if a research paper has many authors, instead of listing them all, you can use et al. after the first author's name. It helps keep the citation neat and saves space. 

Using et al. makes it clear that there are other authors involved without listing all their names. It's a handy shortcut used in academic writing to make things simpler and clearer.

How to Use et al. in Different Citation Formats?

Now that we've explored the significance of et al. in citations let's discover its application across various citation formats.

et al. in APA Style

In APA style, employ "et al." in in-text citations when a work involves three or more authors. Include the first author's name followed by "et al." and the publication year. 

Here are some examples:

et al. in MLA Style

In MLA style, it is used similarly to APA style but with some differences. When citing sources with three or more authors, you include only the first author's name followed by et al. This rule applies to both in-text citations and the work's cited list. If there are only two authors, you list both names.

Here's how it looks:

et al. in Chicago Style

When citing sources with three or more authors in Chicago style, you still include only the first author's name, followed by et al. in the in-text citation.

However, in the bibliography, you list all the authors.

et al. vs etc. What’s the Difference?

While both are abbreviations used in writing, they serve different purposes.

Key Considerations While Using et al. 

Here are the common mistakes to avoid when using "et al." in citations, explained in simpler language:

• Use the right words with 'et al.': If you're talking about a bunch of people, say "Jason et al. are" instead of "Jason et al. is."
• Put the dots in the right place: When you write "et al.," make sure you put a dot after "al" every time. This dot tells people it's a shortcut.
• Keep the dots in order: If you add other symbols after "et al.," like commas or brackets, always put the dot first. For example, write "(Phillips et al., 2013)" instead of "(Phillips et al, 2013)".
• Finish with one dot: When "et al." is at the end of a sentence, use only one dot. Don't use two dots like this: "et al.."
• Use the comma right: If there's a list of names before "et al.," use a comma before "et al." But if there's only one name, don't use a comma.

Correct: "Wood, Mark, et al."

Incorrect: "Wood, et al."

• Write it the same way every time: Use the same style for "et al." every time you mention it. Don't switch between uppercase and lowercase letters.
• Avoid using excessive use; use it only when necessary to avoid confusion.
