PDF download Download Article

"Et al." is a convenient way to reference a work with three or more authors without having to spell out all their names. In this article, we'll explain how to use "et al." when writing academic papers and other publications according to the MLA, APA, and CMS rules for citing sources. We'll also answer if it's appropriate to use "et al." in your salutation when you're emailing multiple people at the same time, with expert insights from English teacher Noah Taxis and etiquette coach Tami Claytor.

When should I use "et al."?

English teacher Noah Taxis says you use “et al.” to abbreviate a list of authors on a publication. Specifically, use "et al." to cite a work by 3 or more authors. For MLA, use it in in-text citations and the Works Cited page. For APA, use it in in-text citations. For CMS, use it in in-text citations and footnotes.

  1. According to Taxis, “Et al. is an abbreviation used to abbreviate a list of authors, or authorship, on a publication.”[1] Some works, like textbooks, journal articles, or anthologies, are written by three or more authors. When you need to cite one of these for an academic paper, writing "et al." is quicker and easier than spelling out the last name of each author in every citation.[2]

  1. When citing a work with three or more authors in the text using the Modern Language Association (MLA) style, write the first listed author's last name, leave a space, then add "et al." If you need to include a page number, avoid putting a period between "et al." and the number. On the Works Cited page, write "et al." after the first author's first name with a comma in between.[4]
    • In-text citation: (Williams et al. 92) or "According to Williams et al., a ship can link three people from the past and future."
    • Works Cited page: Williams, Beatriz, et al. The Glass Ocean: A Novel. HarperCollins, 2018.

How to Write Et Al in APA

  1. When citing a source in the American Psychological Association (APA) style, only use "et al." when quoting or paraphrasing a source in the text of your paper. It's always followed by the year the work was published. Avoid using it on the References page. Instead, when citing works with 3-20 authors, write down every author by their last name and first initial, separated by commas. The last author's name should be preceded by an "&," and their initial followed by the year the work was published in parentheses.[5]
    • In-text citation: (Williams et al., 2018) or "Williams et al. (2018) write…"
    • References page: Williams, B., Willig, L., & White, K. (2018). The glass ocean: a novel. HarperCollins.

How to Cite with Et Al in CMS

  1. The Chicago Manual of Style (CMS) also requires you to add the year the source was published and the specific pages you're citing (if applicable). Unlike in APA formatting, avoid putting a comma between "et al." and the date.[6]
    • Example: (Williams et al. 2018, 102-103)
  2. If a work is written by up to six authors, write the first author's last name, a comma, then their first name. Then, reference all the other authors by first and last name, and separate them by commas. If the work is written by more than six authors, write the names of the first three authors only. After the last name of the third author, write a comma, followed by "et al." and the year the work was published.[7]
    • Example (up to 6 authors): Williams, Beatriz, Lauren Willig, and Karen White. 2018. The Glass Ocean: A Novel. HarperCollins.
    • Example (more than 6 authors): Anders, Charlie J., Margaret Atwood, Joseph Cassara, Jennine C. Crucet, Angie Cruz, Pat Cummings, et al. 2024. Fourteen Days. HarperCollins.

Should you use et al in an email?

PDF download Download Article
  1. "Et al." is used exclusively when citing a source with multiple authors in an academic, scientific, or government publication. This means you shouldn't use it as a salutation when you're communicating with other people through emails, texts, DMs, etc. Instead of opening an email to more than three people, "Dear John, Amy, Lauren, et al.," Claytor suggests using a short phrase like, "Hi, everyone."[8] Below are some other greetings you can try:
    • Hello, all
    • Dear friends
    • Dear colleagues
    • To the company team
    • To all employees
    • However, Taxis notes that “people tend to overuse [“et al.”], which is expanding its colloquial meaning.”[9]

    You should be as specific as possible when naming people in a will, and "et al." is not very specific.
  • Question
    How do I use et al. in a signature?

    Where a formal signature is required, "et al." would not be used, because it refers to a group of people.

Article SummaryX

To use et al., keep in mind that the Latin phrase means "and others" to help you decide where and when to use it. You can use et al. formally when you're creating in-text citations and parenthetical remarks so that you don't have to list a long string of names. You can also use the phrase in less formal situations, like when you need to refer to a group of coworkers in a work email. Et al. works best when written, so try to avoid using it in general, everyday conversations. To learn more about using et al. correctly in citations, read on!
