Getting an Oxford Dictionary citation right comes down to three details: the entry title, the edition or access date, and the format your style guide requires, whether that’s MLA, APA, or Chicago. Mistakes here do more than look sloppy in a research paper. They break the trail a reader needs to verify where your argument’s evidence came from. In this guide, you’ll find the citation format for each style, with copy-ready templates for both the online Oxford English Dictionary (OED) and its print edition.
TLDR: Your Oxford English Dictionary Citation Cheatsheet
- MLA 9 (Online): “Term.” Oxford English Dictionary, Oxford University Press, date of term’s last update, www.oed.com/view/Entry/entry-id. Accessed Date you viewed it.
- APA 7 (Online): Oxford University Press. (n.d.). Term. In Oxford English Dictionary. Retrieved Date you viewed it, from https://www.oed.com/view/Entry/entry-id
- Chicago (Note): Oxford English Dictionary, s.v. “term,” accessed Date, https://www.oed.com/view/Entry/entry-id.
- For Print Dictionaries: Replace URL with publisher info, publication year, and page number.
Why Citing the Oxford English Dictionary Is a Big Deal
Citing a dictionary entry may feel pedantic, but the Oxford English Dictionary (OED) provides essential etymological context that standard definitions lack. It’s a record of historical usage and word origins that can add real depth to your writing. When you cite an entry, you’re not just naming a word. You’re giving your reader a clear, verifiable link back to your research trail. I lost points on a paper once for a messy bibliography, and that lesson stuck: the details in academic writing are never just details. They’re the foundation of your work.
Quick Tip: Check whether you’re using the free Oxford Learner’s Dictionaries or the subscription-based OED before you cite it. They’re separate resources and need separate citations. The OED itself is the comprehensive historical reference, usually accessed through a personal or university library subscription. The same author-as-organization logic applies to other reference works, such as when you cite an encyclopedia entry.
How to Cite Oxford Dictionary MLA 9 Edition
The Modern Language Association (MLA) format is the standard for humanities papers and prioritizes the author, but since dictionary entries aren’t usually signed, an Oxford Dictionary MLA citation starts with the entry title in quotation marks instead. For the full rules on names, dates, and container formatting outside dictionary entries, see essayreply’s MLA citation style guide.
Citing the Online Oxford English Dictionary
But what if you’re using one of those massive print volumes of the OED? Then your citation changes slightly. You’ll need the publication info from the book’s copyright page, including the volume number and page number. And of course, the publisher is also a must-have for this citation.
MLA Works Cited Template:
“Title of Entry.” Oxford English Dictionary, Oxford University Press, the Publisher, Date of last update, URL. Accessed Date of access.
Example:
“Kerfuffle, n.” Oxford English Dictionary, Oxford University Press, Sept. 2024, www.oed.com/view/Entry/103039. Accessed 20 July 2025.
MLA In-Text Citation
For your in-text citation, you just need the entry title in quotation marks. This simple reference points the reader to the full citation in your Works Cited list. For the broader rules on quoting and framing sources in-text, see essayreply’s guide to citing an article in an essay.
Example:
The term was first recorded in the 19th century, initially as “carfuffle” (“Kerfuffle, n.”).
Citing a Specific Definition
What if a word has multiple meanings? The OED is famous for this. MLA has a clear rule for this scenario, which you can read about in detail on their official site, that answers, How do I cite a term in an online or print dictionary that lists several numbered definitions? After the entry title in your in-text citation, add the abbreviation “def.” and the relevant number or letter, matching the capitalization and formatting shown on the OED entry itself.
Example:
While “literally” can mean “in a literal manner,” its informal use as an intensifier is also acknowledged (“Literally, adv.”, def. 1c).
Citing a Print Edition of the OED
If you’re using one of those majestic, hefty print volumes of the Oxford English Dictionary, the citation changes a little. You’ll need the publication information from the book’s copyright page, including the volume number and page number, as well as the publisher, the same core details you’d pull when you cite a book generally.
MLA Works Cited Template (Print):
“Title of Entry.” The Oxford English Dictionary, 2nd ed., vol. Volume Number, Clarendon Press, the Publisher, 1989, p. Page Number.
MLA In-Text Citation (Print):
Your in-text citation should include the page number, so your reader can find the term in your specific print edition.
The etymology of “serendipity” is famously traced back to a Persian fairy tale (“Serendipity,” p. 529).
Citing the Oxford English Dictionary in APA Style
American Psychological Association (APA) style places a big emphasis on the date of publication. Most online dictionary entries don’t list a named author or a page number, so an Oxford Dictionary APA citation treats the publisher or organization as the author instead. For the OED, that’s Oxford University Press. This is the standard APA fallback rule for any reference work published by an organization rather than a person, not something unique to dictionaries. See essayreply’s APA citation style guide for the full name and date rules outside dictionary entries.
A key distinction in APA is whether the source is continuously updated or is a fixed, archived version. The main OED website is an online version that is updated, so we use “(n.d.)” for “no date”. An archived version would have a specific publication date.
APA Reference List Entry
Here’s how to format your reference list entry, which differs from MLA’s Works Cited layout. Each term you cite needs its own full reference.
APA Reference Template:
Oxford University Press. (n.d.). Entry title. In Oxford English Dictionary. Retrieved Date you accessed it, from https://www.oed.com/view/Entry/entry-id
Example:
Oxford University Press. (n.d.). Gobsmacked, adj. In Oxford English Dictionary. Retrieved July 20, 2025, from https://www.oed.com/view/Entry/79224
APA In-Text Citation
APA in-text citations require the author (which is often the group author) and the year of publication. Since the OED online is constantly getting updated, we use n.d. for the date, and it’s also helpful to name the specific term you’re citing.
Example:
The term is a vivid British colloquialism expressing utter astonishment (Oxford University Press, n.d., “Gobsmacked” entry).
For more detailed examples, the official APA Style site provides excellent guidance on Dictionary Entry References, covering both online and print sources. If you need to create many citations quickly, a free citation generator can speed up the process, but always double-check its output for accuracy.
How to Handle Chicago Style (CMOS)
The Chicago Manual of Style is flexible about how to cite OED entries. For a well-known reference work like the OED, Chicago often lets you get away with just a simple note in the text, as long as you stay consistent across your paper. See essayreply’s Chicago citation style guide for the note-bibliography vs author-date rules that apply beyond dictionary sources.
Chicago Note-Only Citation
This is the simplest way to cite the OED in Chicago. The abbreviation “s.v.” stands for sub verbo, which is Latin for “under the word.”
Note Template:
1. Oxford English Dictionary, 2nd ed. (1989), s.v. “term.”
For the Online Edition:
2. Oxford English Dictionary, s.v. “term,” accessed Date, URL.
Chicago Author-Date Style
If your discipline uses author-date parenthetical notes, you’ll need a full reference list citation instead. The official Chicago Style Q&A suggests treating the OED like a book written by its editors, which makes the publisher and volume number essential information for this citation format.
Reference List Entry (Print):
Simpson, J. A., and E. S. C. Weiner, eds. 1989. The Oxford English Dictionary. 2nd ed. 20 vols. Oxford: Clarendon Press, the Publisher.
Your in-text note would then be (Simpson and Weiner 1989), a more formal citation approach for extensive research using the same OED edition.
Common Mistakes and Quick Fixes
A misplaced comma or an incorrect date can make otherwise solid citations look sloppy. Here’s a table of the most common OED citation mistakes, why each one matters, and the quickest way to fix it.
| Common Mistake | Why It’s an Issue | How to Fix It |
|---|---|---|
| Forgetting the access date in MLA. | Online content can change. The access date shows the version you saw. | Always add “Accessed Day Month Year” at the end of your MLA online source note. |
| Using the wrong URL. | A URL from behind a library paywall won’t work for most people. | Use the direct permalink to the definition on the main OED website if possible. |
| Mixing up MLA and APA author formats. | It shows inconsistency across your citations. | Remember: MLA uses full names (“Doe, John”), while APA uses initials (“Doe, J.”). For the OED, this often applies to the editors. |
| Not specifying the volume and page for print versions. | The print OED is massive. Without a volume number and page number, finding the term is nearly impossible. | Always include the volume and page numbers when citing a physical book, and check that they match the edition’s publisher information. |
Handling citations correctly is a core skill for academic work, and the same source-tracking logic behind an Oxford dictionary citation applies to most other reference types.

Frequently Asked Questions
How do you cite Dictionary.com in APA?
In the case of the OED, you can treat the organisation as the author, like this: Dictionary.com (n.d.). Term. In Dictionary.com. Retrieved Date, from URL. The in-text citation would be (Dictionary.com, n.d.): pretty simple.
How to cite the Oxford Dictionary in MLA 9?
For the online version, you use a slightly different format – “Term.” Oxford English Dictionary, Oxford University Press, Date of last update, URL. Accessed Date of access. And then in the in-text note, you just use the term’s title in quotation marks, like this: (“Term”).
How to cite the OED in Bluebook?
And then there’s the Bluebook style, used in legal writing – it’s got its own special format. But for the OED it usually looks like this: OXFORD ENGLISH DICTIONARY 123 (3d ed. 2010) or if you’re referring to a specific definition: OXFORD ENGLISH DICTIONARY s.v. kerfuffle (3d ed. 2010). But be sure to identify the correct edition you’re using when you cite the dictionary. This is pretty much standard for most dictionaries. In MLA, you kick off the Works Cited entry with the title of the term in question. In APA, you get to use the organization that put the dictionary out as a group author – Oxford University Press, for instance. Editors just aren’t included.
What if there is no author listed for a definition?
This is standard for most dictionaries. In MLA, you start the Works Cited entry with the title of the term. In APA, you use the organization that published the dictionary (e.g., Oxford University Press, the publisher) as a group author. The editors are not listed here.
What if the online entry has no copyright date or update date?
If it’s not possible to track down a publication date, APA style falls back on the abbreviation “n.d.” meaning no date. MLA style lets you just leave that element out altogether and move on to the URL and your access date. The OED, on the other hand, usually kicks out a month and year for its latest updates to definitions. But the copyright date is a different story
What’s the fastest way to cite OED across all three styles?
Use the TLDR cheatsheet at the top of this guide: it has the ready-to-fill template for MLA, APA, and Chicago side by side. Swap in the entry title, the organization’s name (Oxford University Press) as the group author, and your access date, and each citation is ready to paste into your reference list.
