• A Word A Day - The site dealing with english words, their origin (etymology) and their usage. Maintained by Anu Garg, the site has a mailing list that delivers a word everyday in your inbox. The site also has an anagram server which is quite interesting. There's also an audio file available to learn the word's pronunciation. Too good to be free, as for me I simply love the thoughts that come with the AWAD mail everyday.
