Understanding Dictionary Citations in MLA

Dictionaries are essential reference sources for understanding word definitions, etymology, and usage. Citing dictionaries in MLA format acknowledges these sources and allows readers to verify definitions and contextual information. Whether you’re citing a traditional print dictionary or an online resource, MLA provides straightforward guidelines.

Basic Dictionary Citation Format

The standard MLA format for dictionary entries is: “Word.” Dictionary Name, Edition, Year, Page Number or URL.

The word being defined should be in quotation marks, the dictionary title in italics, and complete publication or access information included.

When citing an entry from a print dictionary:

“Photosynthesis.” Merriam-Webster’s Collegiate Dictionary, 11th ed., 2014, p. 989.

Include the word in quotation marks, the dictionary title in italics, the edition number, publication year, and page number.

Multiple Entry Words

If you cite more than one word from the same dictionary, you can include multiple entries:

“Paradigm.” Oxford English Dictionary, 2nd ed., 1989, p. 456. “Synthesis.” Oxford English Dictionary, 2nd ed., 1989, p. 789.

Online Dictionary Citation

For online dictionaries, replace the page number with the URL:

“Algorithm.” Merriam-Webster.com Dictionary, Merriam-Webster, 2024, www.merriam-webster.com/dictionary/algorithm.

Dictionary with Editor Information

For specialized dictionaries with credited editors:

“Catalyst.” Dictionary of Chemistry, edited by John Smith, 3rd ed., Academic Press, 2020, p. 234.

In-Text Citations for Dictionary Entries

For in-text citations, use the word being cited:

(“Paradigm”) or (Merriam-Webster) for general reference.

For direct quotes from the definition:

(“Photosynthesis,” Merriam-Webster)

Examples for Different Dictionary Types

Oxford English Dictionary

“Etymology.” Oxford English Dictionary, 2nd ed., 1989, vol. 5, p. 203.

Cambridge Dictionary Online

“Blockchain.” Cambridge Dictionary, Cambridge University Press, 2024, dictionary.cambridge.org/dictionary/english/blockchain.

Specialized Technical Dictionary

“Variable.” Dictionary of Computer Science, edited by Margaret Walsh, 4th ed., Penguin Reference, 2019, p. 567.

Dictionary App Citation

“Eloquent.” Dictionary.com, Dictionary.com, 2024, www.dictionary.com/browse/eloquent.

Using Definitions in Your Writing

When citing a definition, introduce it clearly in your sentence:

According to Merriam-Webster, “paradigm” means “a typical example or pattern of something.”

This approach makes it clear you’re citing a definition and provides context for readers.

GenText Dictionary Citation Support

GenText simplifies dictionary citation by organizing word entries, dictionary titles, and publication information. The tool automatically generates properly formatted MLA citations and maintains consistency throughout your document.

Reference List Formatting

In your works cited page, arrange dictionary citations alphabetically by the word being defined. Use the standard hanging indent format. If citing multiple dictionaries, organize them by dictionary name when the same word appears in different sources.

Common Citation Mistakes

  • Incorrect formatting: Words should be in quotation marks; dictionary titles should be italicized.
  • Missing edition information: Include the edition number (11th ed., 2nd ed., etc.) for print dictionaries.
  • Incomplete URLs: Provide full, functional URLs for online dictionaries.
  • Page numbers vs. URLs: Use page numbers for print; use URLs or DOIs for online sources.

When to Cite Dictionary Entries

While general knowledge doesn’t need citation, citing definitions is appropriate when:

  • Providing a specific word’s technical or specialized meaning
  • Using an uncommon or archaic definition
  • Establishing the formal definition of a key term in your argument
  • Comparing definitions across different dictionaries

Specialized vs. General Dictionaries

Specialized dictionaries (medical, legal, scientific) require complete citation. General dictionaries can sometimes be referenced more briefly, but citation guidelines recommend full formatting.

By following MLA guidelines for dictionary citations, you provide readers with clear reference tools and demonstrate proper research methodology.
