Cite it. I believe you have to cite a dictionary if you use a definition from it in your paper.
edit: From my Hodge's Harbrace Handbook:
14. Reference Book
...
When citing a specific dictionary definition for a word, use the abbreviation
Def. (for "Definition"), and indicate which one you used.
"Reactive." Def. 2a.
Merriam-Webster's Collegiate Dictionary. 10th ed. 2001.
Hope that helps. I know it is coming from MS and not a dictionary, so I'm not sure if you would use that arrangement or not.
