Citing Multiple Authors in APA 7th Edition

If you have an English essay draft open right now, try this 30‑second experiment.

Pick any paragraph and highlight all the “multiple authors” in‑text citations, for example:

• (Li & Wang, 2020)
• Garcia et al. (2021)
• (Chen, Liu, & Zhang, 2019)

Then ask yourself three questions:

1. When there are two authors, do you really know the exact difference between the narrative form and the parenthetical form?
2. For three or more authors in APA 7th edition, is it “write all authors the first time, then use et al.”, or “use et al. from the very beginning”?
3. When the same group of authors shows up again in different sentences and parentheses, are you writing them in a consistent way?

If any of these questions makes you hesitate, you are probably losing points in your essays—
not because you “don’t know APA at all”, but because your citing multiple authors in APA is handled vaguely.

This guide is here to turn that vague zone into a clear, reusable system.

1. First, get clear on what “multiple authors” actually means

Many students memorize APA as scattered details:
where the comma goes, where & goes, when to use and.

A much easier way is to hold a simple structure in your head and only then attach rules to it.

For APA 7th, in‑text citations revolve around three questions:

1. How many authors are there? One / two / three or more.
2. How do they appear in your sentence? Narrative vs parenthetical.
3. If they appear multiple times, do you abbreviate them? Especially with three or more authors and et al.

Once these three are clear, apa in text citation multiple authors becomes much less scary.

One key change in APA 7th is its attitude toward “three or more authors”:

• APA 6th: write all authors the first time, then use et al. later.
• APA 7th: use “first author’s surname + et al.” from the very first citation.

Many old blog posts still describe the 6th‑edition rule, so you’ll see conflicting advice.
In this article, we stick to the latest APA 7th rules only.

2. Two authors: when to use “&” and when to use “and”

Let’s start with the most common—and the most frequently messed up—case: two authors.

Under APA 7th, the rule is very stable:

• In parenthetical citations, use & between authors.
• In narrative citations, use the word and between authors.
• This does not change between first and later mentions.

Some concrete examples:

Parenthetical (inside parentheses)

• Recent studies support this view (Li & Wang, 2020).
• This pattern has been widely observed (Garcia & Brown, 2021).

Narrative (authors as part of the sentence)

• Li and Wang (2020) argue that…
• Garcia and Brown (2021) found that…

You can keep one quick rule in your head:

If the authors are inside the brackets, use &.
If the authors are part of the sentence, use and.

This is one of the core apa in text citation multiple authors rules.
Turn it into muscle memory as early as you can.

Copyable templates for two authors

Paste these and just swap the names and years:

Parenthetical:
(Author A & Author B, Year)

Narrative:
Author A and Author B (Year) argue that …

3. Three or more authors: et al. from the very first citation

In real academic writing, the scenario that causes the most confusion is “three or more authors”.
You might have seen several different rules online; here’s the one that actually matches APA 7th.

Core rule

• For three or more authors, from the first time you cite them:
  write only the first author’s surname + et al. + year.
• This applies to both narrative and parenthetical citations—the position of et al. changes, but the idea is the same.

Parenthetical:

• (Chen et al., 2019)
• (Garcia et al., 2021)

Narrative:

• Chen et al. (2019) found that…
• Garcia et al. (2021) argue that…

Pay attention to these small details:

• There is a space on both sides of et al..
• al. ends with a period because it is an abbreviation.
• et is not abbreviated, so there is no period after it.

Comparing two authors vs three or more authors

A simple table can help you fix the pattern in your mind:

When you are in the middle of writing an essay, you only need to ask:
“Is this two authors or three‑plus?”

Then plug the names into the relevant slot in the table. Your error rate will drop quickly.

Copyable templates for three or more authors

Parenthetical:
(Author A et al., Year)

Narrative:
Author A et al. (Year) argue that …

4. Common “combination scenarios” that break APA rules

Most real‑world mistakes don’t happen in simple single‑citation cases.
They happen when you combine multiple works and multiple authors in the same sentence.

Here are the patterns that show up again and again when professors mark papers.

4.1 Multiple sources in the same parentheses

When one sentence is supported by several studies, you can cite them in the same set of parentheses:

• Sort them by the first author’s surname in alphabetical order.
• Separate each source with a semicolon.

For example:

• Recent studies support this pattern (Chen et al., 2019; Li & Wang, 2020; Zhang, 2023).

In this single parenthetical citation, you are using both the “two authors” rule and the “three‑plus authors” rule at once:
you keep (Li & Wang, 2020) and (Chen et al., 2019) exactly as you would if they appeared alone—
you just put them together and separate them with semicolons.

4.2 Multiple works by the same authors (in the same parentheses)

If the same author team has published multiple papers, you can group the years:

• (Wang & Xu, 2019, 2021)

If they have multiple works in the same year, add a / b and reflect that in your reference list:

• (Wang & Xu, 2021a, 2021b)

The same logic applies when there are three or more authors:

• (Garcia et al., 2020, 2022)
• (Garcia et al., 2021a, 2021b)

The key is consistency: whatever you do in the in‑text citation must match the entries and year labels in your reference list.

4.3 Same surname, different authors

If two authors share the same surname, the combination of surname + year alone is not enough to distinguish them.
In that case, add initials:

• J. Wang and Li (2020) found that…
• L. Wang and Chen (2020) argued that…

Parenthetical citations work the same way:

• (J. Wang et al., 2020; L. Wang & Chen, 2020)

4.4 Group author + multiple individual authors

In one paragraph, you might cite both group authors (organizations) and multiple individual authors.
Group authors are not “multiple personal authors”, but they share the same alphabetical ordering rules.

For example:

• (American Psychological Association, 2020; Chen et al., 2019; Li & Wang, 2020)

Treat the organization name as if it were a surname and sort it alphabetically with the others.

5. How to quickly catch “multiple authors” mistakes when editing

By now you know the main rules for apa in text citation multiple authors.
What actually affects your grade, though, is whether you run a systematic check before submission.

If you are writing manually in Word or Google Docs, the checking steps in this section are crucial.
If you are working in Knowee Writer and using its built‑in citation tools, APA 7th‑style multi‑author in‑text citations (such as (Li & Wang, 2020) and Chen et al. (2019)) are generated automatically for you; your main job is to make sure the sources themselves are correct and relevant to your argument.

Either way, a short checklist focused on “multiple authors” will help you clean up tiny but costly errors.

5.1 A small checklist: five questions to ask before you submit

Read through your essay once. Every time you see a citation, ask:

1. Two authors: Are you using & in parentheses and and in narrative form?
2. Three or more authors: Are you using Author A et al. (Year) / (Author A et al., Year) from the first mention, and doing it consistently?
3. Multiple sources in one parenthesis: Are they sorted alphabetically by first author’s surname, separated by semicolons?
4. Multiple works by the same authors: Are you grouping the years correctly (for example (Wang & Xu, 2019, 2021)), and adding a / b for same‑year works?
5. Same surname, different authors: Have you added initials where needed (for example J. Wang vs L. Wang)?

Run this checklist once and you will catch most “citing multiple authors in APA” mistakes.

5.2 Use search and replace to normalize your format

Beyond eyeballing, a few simple search tricks can stabilize your APA formatting:

• Search for et al to check spacing and punctuation around et al. and ensure every al. ends with a period.
• Search for and to verify that and only appears in narrative citations, while all parenthetical citations use &.
• Search for ; to scan multi‑source parentheses and confirm they are alphabetized by author.

5.3 When adding new sources, format them in “template style” first

Most citation chaos appears later in the process, when you add new sources to an almost‑finished draft.

A simple way to avoid this:

1. When you decide to add a new source, write its author(s) and year in a scratch area at the bottom of your document and format it using the templates from this article—for example (Author A & Author B, Year) or (Author A et al., Year).
2. After you are sure the format is correct, cut that citation and paste it into the sentence where you need it.

You can reserve a small “template zone” at the bottom of each essay draft, where you store:

• Standard in‑text citation formats for two authors and three‑plus authors;
• Example structures for multiple sources in one parenthesis and multiple works by the same authors.

Every time you introduce a new source, bring it through this zone first, then into the main text. It saves you from doing an exhausting last‑minute clean‑up.

6. Copy‑and‑paste templates for multiple authors (Knowee Writer‑friendly)

To finish, here is a compact toolkit you can paste into the bottom of any Knowee Writer document.
Whenever you need to cite multiple authors, copy from here and change the names and years.

[Two authors]
Parenthetical:
(Author A & Author B, Year)

Narrative:
Author A and Author B (Year) argue that …

[Three or more authors]
Parenthetical:
(Author A et al., Year)

Narrative:
Author A et al. (Year) found that …

[Multiple sources in one parenthesis]
(Author A, Year; Author B & Author C, Year; Author D et al., Year)

[Multiple works by the same authors]
Different years:
(Author A & Author B, 2019, 2021)

Same year:
(Author A et al., 2021a, 2021b)

[Same surname, different authors]
J. Wang and Li (2020) argue that …
L. Wang and Chen (2020) suggest that …

Once you get used to using this small toolkit for apa in text citation multiple authors, APA stops feeling like a pile of scattered rules and starts to feel like a writing habit you’ve stored in your muscle memory.
