Pet & Animal: How to Cite a Dictionary

When a specific definition has been used in an essay, you will need to cite the dictionary in your “Works Cited” or “References” page. Each style guide has its own citation standards, and these standards vary depending on whether the dictionary is a print source or an online source.

Section 1: Print Dictionary in MLA^[1]

State which word you defined. The word should be capitalized an enclosed in quotation marks. Follow it with a period.
- “Citation.”

Indicate the definition number. If the term has more than one definition in the dictionary, indicate which definition you used. A number indicates the entry number, since some words have more than one entry, and a letter indicates the definition under the entry number used. End the line with a period.
- "Citation." Def. 1e.

Identify the dictionary you used to define the word. Type the name of the dictionary in italics and follow it with a period.
- "Citation." Def. 1e. Merriam-Webster's Collegiate Dictionary.

List the year of publication. The full publication date is not necessary. You only need to indicate the year that the particular version of the dictionary you used was published in, following it with a period.
- "Citation." Def. 1e. Merriam-Webster's Collegiate Dictionary. 2003.

Specify that the dictionary was in print. Since sources can be in multiple mediums, the MLA style requires you to specify the medium you used. Here, it would simply be “Print.”
- "Citation." Def. 1e. Merriam-Webster's Collegiate Dictionary. 2003. Print.

Section 2: Online Dictionary in MLA^[2]

Identify the cited word. Capitalize the word and surround it by quotation marks. Place a period after it.
- "Citation."

Indicate the original source. Third-party online dictionaries often borrow definitions from published print dictionaries. The dictionary that a set of definitions was taken from is usually indicated at the bottom of dictionary entry. Italicize the name of this original dictionary and write a period after it.
- "Citation." Random House Dictionary.

Identify where the location, publisher, and year of original publication. For a publishing house in a major city, like New York or London, only the city name needs to be given. If it is a U.S. city that is not well known, however, include the state. Follow the location with a colon and the name of the original publisher. After that, type a comma and the year of the dictionary’s original publication.
- "Citation." Random House Dictionary. New York: Random House, Inc., 2012.

Specify the online publication source. The online publication source is the online dictionary you got the definition from. You only need to indicate the name of the online dictionary, not the URL.

State that the definition came from the Web. MLA formation requires you to indicate which type of medium a specific source came from.

Conclude with the date the definition was accessed. Include the day, month, and year. You do not need to introduce the date in any special way, but you should finish it with a period.
