A great vocabulary resource

I love the site VOCABULARY.COM as a way to learn new words. Instead of just defining the words, like a dictionary, vocabulary.com also explains the words--it gives a more "user-friendly" explanation of where you might see a word and how you might use it. You can also check out some of their vocabulary lists, like 100 SAT words, 10 Words from Today's New York Times, etc. It's a very useful site for those of you looking to build your vocabulary...check it out!
