If you want to go out of your way to help your readers, you can link directly to the definition straight from the word like this: [noparse][url=http://dictionary.com/browse/magniloquent]magniloquent[/url][/noparse]
which produces this: [url=http://dictionary.com/browse/magniloquent]magniloquent[/url]

Alternately, if you're using Chrome or Firefox (don't know about other browsers), you can highlight the word, right click it, and choose "Search Google for 'highlighted word'". Hope that helps!
