  • Date
  • Title of the encyclopedia entry or word being used
  • Location & publisher information
  • An edition
  • Web address (URL) for source if found online

Reference page entry (unknown author):

Therapy. (2010). In Collins Canadian Dictionary (1st ed., p. 621). Toronto, ON: HarperCollins Publisher.

In-text citation:

(Therapy, 2010)

Note: Use pp. if the entry spans multiple pages; use p. if the entry is only on a single page.

Many free, online dictionaries exist. The following example shows how to cite an entry / definition from :

Reference page entry:

Therapy. (n.d.). In Unabridged. Retrieved from

In-text citation:

(Therapy, n.d.)

Definitions can be obtained from Google by adding "define:" to the start of your search terms.

Sample Google definition search for "therapy"

However, if you require a definition to use in your assignment, it's better to use a standard web-based or printed dictionary for the purposes of citing. Google draws from a number of sources to create this definition, and it's not always easily to identify their source.

Choose an electronic or printed dictionary from the library, or use a free dictionary online for your definition.


Wikipedia & other wiki type sites
