How Do You Write Et Al In A Sentence? | APA MLA Rules

Write “et al.” after the first author’s last name, put the period after “al.”, and follow your citation style’s year, commas, and page rules.

You’ll see et al. in research papers, lab reports, and essays any time a source has a long author list. It’s a tiny abbreviation, yet it can make your writing look polished or messy in one line.

This guide shows how to place it in a sentence, how to punctuate it, and how to keep APA and MLA readers happy. You’ll get model sentences you can copy, plus quick checks you can run before you submit. You might have typed “how do you write et al in a sentence?” into a search box because one small mark felt unsure. No stress.

What Et Al. Means And When Writers Use It

Et al. is short for a Latin phrase that means “and others.” In practice, it stands in for extra author names you’re not listing out.

Most students meet it inside citations, yet you’ll also see it in general academic prose when a text refers to a study team or a report group.

Where Et Al. Shows Up Most

  • In-text citations: You cite one author name, then et al., then the year or page number, based on style.
  • Signal phrases: You work the citation into the sentence itself: author name + et al. + year.
  • Reference lists and Works Cited entries: Many styles shorten long author lists there too, with rules that differ from in-text rules.

Punctuation And Spacing That Make Et Al. Look Right

The fastest way to spot a weak citation is the punctuation. Get the dots and commas right and you’re halfway done.

Periods, Italics, And Capital Letters

  • Use a period after “al” only: write et al., not et. al. (no period after et).
  • Keep it lowercase in running text: write et al., not Et Al., unless it starts a sentence.
  • Don’t add an apostrophe: it’s not et al’s. If you need possession, rephrase or use a plural noun phrase.
  • Use a space between the words: write et al., not etal..

Comma Placement Depends On Your Style

APA and MLA treat commas and years in different ways. That’s why a line can look fine in one class and look off in another.

Situation Write It Like This Notes
APA narrative citation Garcia et al. (2022) report … No comma before et al.; year goes in parentheses.
APA parenthetical citation (Garcia et al., 2022) Comma before the year in APA parentheses.
APA with page number (Garcia et al., 2022, p. 41) Add page when you quote; use “p.” for one page.
MLA narrative mention Garcia et al. argue that … No year in MLA narrative text.
MLA parenthetical citation (Garcia et al. 41) Author + page, no comma and no year in the parenthesis.
MLA Works Cited author slot Garcia, Marisol, et al. Comma use changes when a name is reversed.
General prose, no citation Garcia et al. published the report. Use this only when your reader already knows the source.
Chicago author-date in text (Garcia et al. 2022, 41) Year is used; comma rules differ from APA.

Et Al. In The Middle Of Your Sentence

Sometimes you don’t want a full citation. You just want to name the research team in prose. That can work in literature reviews where the full reference is already in your bibliography.

Use the author’s last name plus et al. as a compact subject, then keep the verb close so the sentence doesn’t wobble.

  • Rahman et al. describe the method in the opening section.
  • Hossain et al. list the variables in Table 2.

Avoid possessives built on et al.. If you need ownership, attach it to a noun that reads cleanly.

  • Less clean: Rahman et al.’s findings
  • Cleaner: the team’s findings
  • Also clean: the authors’ findings

How Do You Write Et Al In A Sentence? In Text And In Parentheses

Start with one decision: are you writing the authors as part of the sentence, or are you dropping the citation in parentheses at the end?

Once you pick that lane, the structure stays steady. The details that shift are the commas, the year, and the page number.

Signal Phrase Pattern

This pattern reads smoothly because the author group becomes the subject of the sentence.

  • Pattern: Lastname et al. (Year) + verb …
  • Model sentence: Rahman et al. (2021) describe a clear link between study time and quiz scores.

Parenthetical Pattern

This pattern keeps your sentence focused, then adds the source at the end.

  • Pattern: Sentence … (Lastname et al., Year).
  • Model sentence: Students improved after weekly practice sessions (Rahman et al., 2021).

What To Do When Et Al. Starts A Sentence

Starting a sentence with et al. looks odd because it has no named author attached. If you need to begin a new line, lead with the author’s last name instead.

Model sentence: Rahman et al. (2021) note that short quizzes work well when they’re frequent.

APA Style Et Al. Sentences You Can Copy

APA uses author-date citations. For works with three or more authors, APA shortens the author list in in-text citations to the first author’s last name plus et al.

If your instructor expects APA 7, the big win is consistency: the same author-shortening pattern stays in place each time you cite that work.

APA Narrative Citations

Use narrative citations when the author group is part of the claim you’re making.

  • Hossain et al. (2020) find that spaced practice helps students retain vocabulary.
  • Ahmed et al. (2019) report that feedback works best when it’s tied to a rubric.

APA Parenthetical Citations

Use parenthetical citations when you want to keep the spotlight on the idea, not the researcher names.

  • Students did better after retrieval practice (Hossain et al., 2020).
  • Clear rubrics reduce confusion (Ahmed et al., 2019).

APA Quotations And Page Numbers

If you quote, add a locator. APA often uses a page number when one exists.

  • “Short quizzes can raise attention” (Hossain et al., 2020, p. 118).
  • Ahmed et al. (2019) write that “rubrics make expectations visible” (p. 44).

If you want to double-check the broad APA author-date pattern, the APA author-date citation rules page lays out the structure.

MLA Style Et Al. Sentences For Essays

MLA in-text citations use the author’s last name and a page number. When a work has more than two authors, MLA lets you use the first author’s last name followed by et al.

That changes the rhythm of your sentences. You’ll notice MLA citations can feel lighter because they skip the year.

MLA In A Signal Phrase

Use this when you’re summarizing a point from a group-authored book or article.

  • Chowdhury et al. argue that narration shapes how readers judge a character.
  • Hasan et al. write that word choice can shift tone in a single paragraph.

MLA In Parentheses

Place the citation close to the line that uses the source, then end the sentence.

  • Readers notice tone shifts fast (Chowdhury et al. 73).

Comma rules can trip people up in MLA Works Cited entries. The MLA Style Center note on commas with et al. shows when a comma appears and when it doesn’t.

Chicago Style Et Al. Sentences When You Need Them

Some courses use Chicago style, often with notes or an author-date system. When you’re in author-date mode, Chicago commonly shortens multi-author citations with et al. in the text.

If your assignment sheet says “Chicago author-date,” watch the comma and spacing pattern your instructor gives you. Keep your paper consistent with that sheet.

Chicago Author-Date In Parentheses

  • (Karim et al. 2018, 22)
  • (Sultana et al. 2021, 109–10)

Chicago In A Sentence

  • Karim et al. (2018, 22) link sleep routines to attention in class.

When Not To Use Et Al.

Et al. is a tool, not a default. There are times it weakens clarity, even when it’s allowed.

Cases Where Spelling Out Names Works Better

  • Two-author works: Many styles want both names in text, not et al..
  • Group authors: If the author is an organization, use the organization name, not et al..
  • Legal or policy writing: Readers may expect the full author list or a formal short title, depending on local rules.

When Different Papers Start With The Same Author

A common snag: you have two sources that both start with the same first author and the same year. If both become “Rahman et al. (2021),” your reader can’t tell which is which.

Styles handle this in different ways, like adding another author name or adding letters to the year. Follow your style guide or your instructor’s sheet when this happens.

Table Of Common Et Al. Mistakes And Clean Fixes

Run through these fixes while editing. You’ll catch the tiny issues that graders spot fast.

Mistake Why It Looks Wrong Fix
et. al. Extra period after et Write et al. with the period after al only.
Et Al. Odd capitalization in mid-sentence Use lowercase: et al. unless it begins a sentence.
Smith, et al. Comma before et al. in places many styles don’t use In APA narrative text, drop the comma: Smith et al. (2020).
(Smith et al 2020) Missing comma and period, missing punctuation APA: (Smith et al., 2020). MLA: (Smith et al. 41).
et al’s Incorrect possession Rewrite: “the authors’ claim” or “the research team’s claim.”
Using et al. with 2 authors Style mismatch List both names if your style calls for it.
Mixing APA and MLA in one paper Year and commas jump around Pick one style and apply it on every citation.
Starting a sentence with et al. No clear author attached Start with the author’s last name: Rahman et al. (2021).

Quick Editing Pass Before You Submit

Before you submit, do a quick sweep. It takes a minute and saves you from the classic “looks sloppy” comments.

Five Checks That Catch Most Errors

  1. Scan for et. al. and change it to et al..
  2. Check your commas: APA parenthetical citations use a comma before the year; MLA parenthetical citations don’t.
  3. Check your year use: APA uses it in-text; MLA usually doesn’t.
  4. Check page numbers on quotes: add the locator your style expects.
  5. Read one paragraph out loud. If the citation breaks the flow, switch between narrative and parenthetical style.

If you’re still asking “how do you write et al in a sentence?” while editing, stick to one pattern, then apply it line by line. A steady pattern beats a clever line that breaks the style rules.

One last tip: if your teacher gave you a department handout, follow it even when it differs from a web guide. That handout is what your paper will be graded against.
