OmniDictionary is a Mac OS X client for network dictionary servers. It's pretty straightforward - type a word into the entry field, hit return, and the definition is displayed. If the dictionary server supports multiple dictionaries, you can select your desired dictionary from the dictionary popup to limit queries to that specific dictionary, or you can query all the dictionaries. OmniDictionary also provides a "Define in OmniDictionary" Service, so you can select words in your other applications and hit Command-= to see the definition.
