“Et al.” is an abbreviation of the Latin phrase meaning “and others.” It comes from “et alii” (or the neuter “et alia”) and is used mostly in academic and formal writing to shorten a long list of authors in a citation. Instead of naming every contributor to a source, a writer can name the first author and add “et al.” to cover the rest.
What does et al. mean?
Et al. literally means “and others.” The “et” is the Latin word for “and,” and “al.” is a shortened form of “alii,” “alia,” or “aliae,” the Latin words for “others.” Put together, it lets you reference a work with multiple authors without listing them all every time, keeping citations compact and readable.
Why is there a period after al but not et?
The punctuation trips people up, but the rule is logical. “Et” is a complete word on its own, so it needs no period. “Al.” is an abbreviation of a longer Latin word, so it takes a period to mark that letters have been dropped. That is why the correct form is “et al.” and not “et. al.” or “et al” without the period.
When do you use et al. in citations?
The exact threshold depends on the citation style you are following, so it is worth checking the specific rules.
- APA: use “et al.” for in-text citations of sources with three or more authors.
- MLA: use “et al.” for sources with three or more authors, in text and in the Works Cited list.
- Chicago: use “et al.” in in-text citations for four or more authors, with different rules for the bibliography.
Because the details differ, always confirm the requirements of the style guide assigned to your work.
How do you use et al. correctly?
In practice, you name the lead author and follow with “et al.” to represent the remaining authors. For example, a paper by Garcia, Lee, and Patel might be cited as “(Garcia et al., 2021).” Note that “et al.” replaces names of people, so it should not be used to stand in for other kinds of items.
- “(Nguyen et al., 2019) found similar results.”
- “According to Smith et al., the trend continued.”
How do you pronounce et al.?
Et al. is usually spoken aloud as “et al,” with “al” rhyming with “pal.” Some people emphasize it as “et AL.” Either way, it reflects the phrase’s Latin origins and is widely understood in academic settings.
In short, et al. means “and others.” It is a small but essential tool in citations, letting writers credit a source’s lead author while neatly acknowledging the rest of the team behind the work.
