NOOK comes with a dictionary built-in. I don't know what else you're looking for, since the "find" function on NOOK is very primitive and looking up words in a separate dictionary e-book would be frustrating.
If you're still determined, your B&N account came with Merriam-Webster's Pocket Dictionary already loaded on it. Fictionwise carries some dictionaries.
