Wordorigins.org

Wordnik.com is a new online dictionary that has as its goal to include as much information possible about “all” the words in English. The idea is that an online dictionary should not be restricted by the space limitations of print. I haven’t had much time to play with it, but it looks good at initial glance, and it’s created by Erin McKean, Grant Barrett, and Orion Montoya, so it has a good pedigree.
