Adopt an Obsolete Word from the Oxford English Dictionary Oxford English Dictionary Lets You Save the Words
The Oxford English Dictionary has launched something very charming and playful: a campaign to save forgotten words from obsolescence. As you move your mouse over the collage of words they call out for you to pick them, and when you click, a definition pops up, as well as an invitation to adopt it. I just adopted primifluous. I also learned that vitamin G was the original name for riboflavin.
