“Et Al.”: Meaning & Uses in different Citation Styles

Et Al. Meaning:

“Et Al.” is a Latin phrase meaning “and others”. It is commonly used in academic writing when referring to a group of authors in a scholarly work or research paper.

For example, if a research paper has several authors, the first author is listed followed by “et al.” to indicate that there are other authors who contributed to the work. The use of “et al.” helps to simplify the citation and saves space in the reference list.

When & How to use Et Al.

In academic writing, it is important to properly cite all sources used, including the authors of any works or research that has been referenced. When there are multiple authors, it can be cumbersome to list all of their names in a citation or reference. To make this process easier, the first author is listed, followed by “et al.” to indicate that there are additional authors who contributed to the work.

In general, “et al.” is used to simplify citations and make it easier to refer to multiple authors in a work. It is most commonly used when there are three or more authors. In that case, instead of writing down all authors in a citation, the first author is listed followed by “et al.”.

You must be wondering why we use a period after “Et al.”. Keep in mind that the letter “al.” stands for Alia and all of its many forms including Alibi and Alii. The period after “al” shows that it is an acronym.

Et Al. vs. Etc.

“Et al.” and “Etc.” should not be confused with each other as the former is employed to mention people, while the latter is utilized for citing things or ideas.

For Example:

“The book includes contributions from Smith, Johnson, et al., covering various topics such as economics, history, and politics, while the appendix contains a list of abbreviations for academic journals, newspapers, and magazines, etc.”

Understanding the Use of Et Al. in different Citation Styles:

When using “et al.” in academic writing, it is important to understand the guidelines and conventions of the citation style you are using. Different citation styles have different rules regarding the use of “et al.”, such as the number of authors to list before using “et al.”, how to format the citation, and when to use “et al.” in in-text citations versus reference lists.

APA Style:

If a document has two authors, mention both in the in-text citation. In the seventh edition of the APA format, when citing a work with three or more authors, include the last name of the first author in the signal phrase or parenthesis, and follow it with “et al. In the 7th edition, “et al.” is only implemented for in-text citations and not in the reference list.

For example:

In-text citation: (Smith et al., 2019)

Reference list:

Smith, J., Brown, R., Davis, M., & Johnson, T. (2019). The effects of exercise on mental health. Journal of Health and Fitness, 23(4), 1-10.

MLA Style:

Considering MLA just has basic criteria, it’s quite easy to credit sources with multiple authors. If a source has three or more authors, use “et al.”, and always repeat the citation when it appears again. This is applicable for both works cited references and in-text citations that list multiple authors.

For example:

In-text citation: (Smith et al. 23)

Works Cited:

Smith, John, et al. “The effects of exercise on mental health.” Journal of Health and Fitness, vol. 23, no. 4, 2019, pp. 1-10.

Chicago Style:

Chicago style recommends mentioning all author names in the in-text citations when a source has one to three authors. However, for sources with four or more authors, it is acceptable to use the first author’s name followed by “et al.” and the year of publication in the in-text citation.

For example:

In-text citation: (Smith et al. 2019)

Reference list:

Smith, John, Harvey Secter, Ryan Brown, and Ross Johnson. 2019. “The effects of exercise on mental health.” Journal of Health and Fitness 23 (4): 1-10.

If there are more than 10  authors of a source, list the first seven, followed by “et al.” If the number of authors is less than 10, mention all of them in the reference list
