How do I cite a dictionary?

If you are creating an in-text citation for a dictionary entry, you would follow APA's standard in-text citation guidelines of including the first part of the reference and the year. For example, your in-text citations might look like this: (Merriam-Webster's Collegiate Dictionary, 1999) or (Onomatopoeia, n.d.). These in-text citations would then align with your reference list citations. 

If you are citing a full dictionary in your reference list, you would place the title of the dictionary in the position where the author’s name would normally go, so it would look like this:

Merriam-Webster’s Collegiate Dictionary (10th ed.). (1999). Merriam-Webster Incorporated.

If you are citing a single entry in an online dictionary, you will need to include the word that you looked up first, so it would look something like this:

Onomatopoeia. (n.d.) In Merriam-Webster’s collegiate dictionary. http://www.merriam-webster.com/dictionary/onomatopoeia
