Is one of the words I have learned within the last few years and now count it among my favorites. It seems like the rate of learning new words (let alone remembering them or having opportunity to use them in context) has diminished significantly for me. Until it is time for J to do vocab word flashcards and the like, it will probably remain this way.

Wordnik lets you look up words and tells you a bunch of stuff about it. It is still in beta and has several functions that are yet to be fully fleshed out. There is even a real time references to your word in Twitter - so you get a sense of how often and how many folks are using the word you just looked up.
