Save the words!

The fine people at Oxford English Dictionaries have started SaveTheWords.org, a website devoted to reviving thousands of gloriously obscure English words that have fallen out of daily use. Visitors are encouraged to "adopt" a word and begin using it as often as possible. I'm torn: I could probably find some way to work "vappous" into my daily conversation (it means "flat, bland"), but "locupletative" (defined as "tending to enrich") just rolls off the tongue, doesn't it?
