how to cite an online dictionary in apa style: start with the entry title, add n.d., then include a retrieval date and full entry URL in references.
You found a sharp definition in an online dictionary and now you need to cite it in APA. Yep, it gets tricky with no author, no date, and entries that update. This page shows the way to write the reference entry and the in-text citation in APA 7.
You’ll get copy-ready templates, a fast path for “no author” cases, and a checklist you can run before you submit.
What Counts As An Online Dictionary Source
An online dictionary source is a specific entry page on a dictionary website, not the dictionary’s homepage. In APA, you usually cite the entry you used (the word you looked up), since that’s the page your reader needs to see.
Most dictionary sites update entries over time. That’s why APA often asks for a retrieval date for online dictionary entries, since the wording you saw may not stay the same.
Quick Formats For Common Online Dictionary Cases
| Situation | Reference List Pattern | In-Text Citation Pattern |
|---|---|---|
| No entry author listed | Entry title. (n.d.). In Dictionary Name. Retrieved Month Day, Year, from URL | (“Entry title,” n.d.) or Entry title (n.d.) |
| Entry has a named author | Author, A. A. (Year). Entry title. In Dictionary Name. Retrieved Month Day, Year, from URL | (Author, Year) |
| Dictionary uses a group author (same as site) | Group Name. (n.d.). Entry title. In Dictionary Name. Retrieved Month Day, Year, from URL | (Group Name, n.d.) |
| Entry shows a date for the definition page | Entry title. (Year, Month Day). In Dictionary Name. URL | (“Entry title,” Year) |
| Entry is archived and does not change | Entry title. (Year). In Dictionary Name. URL | (“Entry title,” Year) |
| You cite the whole dictionary (rare) | Dictionary Name. (Year). Dictionary Name. Publisher. URL | (Dictionary Name, Year) |
| Print dictionary entry | Entry title. (Year). In Dictionary Name (Edition, p. xx). Publisher. | (“Entry title,” Year) |
| More than one definition from the same entry | Same as your entry format; cite once per entry page | Same as your entry format |
How To Cite An Online Dictionary In APA Style For Most Papers
In APA 7, a dictionary entry reference is built from four pieces: the entry title, the date, the source (dictionary name), and the URL. The “author” piece changes based on what the page gives you. Many online dictionaries do not list individual authors, so the entry title often moves into the author position.
APA Style posts a set of official models for dictionary entries, with patterns for online and print sources. When you want to double-check a format, use APA Style’s dictionary entry references and match your case to the closest pattern.
If you’re stuck, how to cite an online dictionary in apa style comes down to matching the entry page to the closest pattern, then copying the same lead element into your in-text citation.
Step 1: Confirm You’re Citing An Entry Page
Open the page that shows the definition you used. The URL should point to the entry itself, not a search results page. If the site shows multiple senses on one page, you still cite the same entry URL.
Step 2: Decide What Goes In The Author Spot
Look near the entry title and page footer. If you see a person’s name tied to the entry, use that person as the author. If you see an organization name that clearly owns the dictionary, use that organization as the author.
If you see no author at all, start the reference with the entry title. It fixes most “no author” problems quickly.
Step 3: Handle The Date The APA Way
If the entry page shows a posted date, use it. If the page shows only “updated” information with no clear date, treat it as no date and use n.d. in the reference.
For online dictionary entries that are designed to change, APA calls for a retrieval date in the reference. APA also explains retrieval dates in its general reference rules; see elements of reference list entries for the official retrieval-date rule.
Step 4: Write The Title And Source Correctly
Use the entry title in sentence case. That means you capitalize the first word and any proper nouns. Then write In and italicize the dictionary name. APA treats the dictionary name as the “source,” so it gets the italics.
If the entry title contains a headword that is already in lowercase, keep it as the site prints it. APA wants accuracy for titles.
Step 5: Add The Retrieval Date And URL
Write “Retrieved Month Day, Year, from” and then add the full entry URL. Use the most direct URL that loads the entry page.
Skip “Retrieved from.” APA 7 uses “Retrieved …, from” when a retrieval date is needed.
In-Text Citations For Online Dictionary Entries
In-text citations match the first element of your reference list entry. That means you may cite a person, an organization, or the entry title, depending on your reference.
When The Entry Has No Author
If your reference starts with the entry title, your in-text citation starts with the entry title too. Put the entry title in double quotation marks, then add the year or n.d.
- Parenthetical: (“metacognition,” n.d.)
- Narrative: “metacognition” (n.d.) notes that …
In your paper, keep the entry title exactly as it appears on the dictionary page. If the entry is long, shorten it with the first words, as long as it still matches the reference list entry.
When The Author Is A Group Or A Person
If the entry lists an author, use the standard author-date form.
- Parenthetical: (Merriam-Webster, n.d.)
- Narrative: Merriam-Webster (n.d.) defines …
If you quote a definition word-for-word, add a locator if the page offers one. Many entries lack page numbers, so paraphrasing is often cleaner.
Templates You Can Copy Without Guesswork
Use these templates as fill-in lines. Replace the bracketed parts with what you see on the entry page.
Keep the entry title in sentence case, and italicize only the dictionary name, not it.
Template: No Author, No Date
Entry title. (n.d.). In Dictionary name. Retrieved Month Day, Year, from URL
Template: Group Author, No Date
Group author. (n.d.). Entry title. In Dictionary name. Retrieved Month Day, Year, from URL
Template: Entry Has A Full Date
Entry title. (Year, Month Day). In Dictionary name. URL
Template: Print Dictionary Entry
Entry title. (Year). In Dictionary name (Edition, p. Page). Publisher.
Common Mistakes That Cost Points
Dictionary citations go wrong in the same few ways. Fix these and your reference list starts to look clean across your whole paper.
Mistake 1: Citing The Homepage Instead Of The Entry
If your URL ends at the site root or a search page, readers can’t land on the definition you used. Always link the entry page.
Mistake 2: Dropping The Retrieval Date When The Page Changes
Online dictionaries update wording, usage notes, and sample sentences. A retrieval date tells your reader when you saw that version of the entry.
Mistake 3: Treating The Entry Title Like A Book Title
In APA, the entry title is not italicized. The dictionary name is italicized. Mixing these up is easy, so check this line every time.
Mistake 4: Making The In-Text Citation And Reference Start Differently
If the reference starts with the entry title, the in-text citation must start with the entry title too. If the reference starts with an author, the in-text citation starts with that author.
Second-Pass Checks For Tricky Situations
Some dictionary pages give you extra details that change what you write. Run this section when your first draft citation feels odd.
Entries With A Listed Editor
Many online dictionaries do not show an editor per entry. If a dictionary lists editors for the whole work, you usually still cite the entry using the entry title or author and the dictionary name, without adding an editor, unless the site clearly ties an editor to the entry as the author line.
Multiple Entries From The Same Dictionary
If you cite two different entry pages from the same dictionary, create two separate reference entries, each with its own URL. In text, the citations will differ by entry title or by author-year, depending on your setup.
When A Dictionary Has Both A Date And Frequent Updates
Some entries show an “updated” date. Use the date the site provides and keep the URL. If the site is unarchived and changes often, add a retrieval date.
Decision Table For Building A Clean Reference Entry
| What You See On The Entry Page | What You Put First | What You Add Near The End |
|---|---|---|
| A person’s name on the entry | That person as author | Retrieval date if the entry changes; URL |
| Only a dictionary brand or organization name | That organization as author | Retrieval date if the entry changes; URL |
| No author line at all | Entry title in author position | Retrieval date; URL |
| A clear posted date for the entry | Author or entry title | No retrieval date needed; URL |
| No date anywhere | Author or entry title | Use (n.d.); add retrieval date; URL |
| An edition and page number (print) | Entry title in author position | Add edition and page; no URL unless it’s an e-book |
| You used the entry for a quick definition only | Same entry citation rules | Keep the entry URL so readers can verify the wording |
| The site blocks deep links | Entry title in author position | Use the closest stable URL that opens the entry |
Using Your Dictionary Citation In The Body Text
Once you’ve built the reference entry, use the matching in-text citation right where you use the definition. If you paraphrase, place the citation at the end of the sentence. If you define a term at the start of a paragraph and keep using that meaning, cite it the first time you define it, then keep writing in your own words.
If you define more than one term from the same dictionary, keep your reference list alphabetized by the first element of each entry. Entry-title references alphabetize by the first word of the entry title, not by the dictionary name.
Final Checklist Before You Submit
- Your reference links to the entry page, not a homepage or search page.
- The first element of the reference matches the first element of your in-text citation.
- You used n.d. only when the entry page gives no date.
- You added a retrieval date when the entry is designed to change over time.
- The entry title is in sentence case and not italicized.
- The dictionary name is italicized.
- Your URL works when pasted into a new tab.
Read the reference aloud once. If it points back to the exact entry page, you’re set.
