LONDON (Aug. 6) -- Ever engaged a freegan in nonversation, or does the very idea make you want to precuperate? If you haven't a clue what we're talking about, don't worry, you're probably not xenolexic.

The bizarre terms used in those last two sentences are "non words": Words that have allegedly been submitted to the Oxford English Dictionary -- the gatekeepers of the English language -- but rejected on the grounds that too few people currently use them. Some of these non words are hyper-local slang, while others briefly spring in and out of existence when they're deployed to describe short-lived phenomena. A freegan, for example, is an eco-campaigner who hunts for goodies in other people's trash; a nonversation is a vapid, pointless chat; to "precuperate" means to get ready for an oncoming illness; and, perhaps most appropriately of all, a xenolexic is someone who suffers intense confusion when faced with new words.

Recently graduated graphic designer Luke Ngakane, 22 -- who this summer made forgotten phrases the focus of his final art project at Kingston University, London -- told AOL News that many more failed words are hidden away in a secret vault at Oxford. According to British daily The Telegraph, this word bank houses 50 large filing cabinets, each crammed with thousands of 6-by-4-inch cards detailing every declined entry. Some of these slips were scribbled before 1918 -- the year "Lord of the Rings" author J.R.R. Tolkien was hired as an OED sub-editor. (He'd go on to spend many hours puzzling over the etymology of "walrus" and the definition of "waggle.") New non-words are now stored on computers.

After hearing about the vault from another artist, Ngakane decided he'd try to save some of the lost phrases. He contacted Oxford University Press, OED's publishers, and asked if he could roam around among the archives. They confirmed the vault's existence but ignored his plea for access. Unwilling to abandon the project, he trawled the Internet, looking for amateur lexicographers who say their dictionary contenders had been denied by OED authorities.

Through his own research and logophile contacts, Ngakane quickly built up a pamphlet's worth of non words. He selected 39 that "had a lovely flow, or perfectly fit the thing they're describing, like polkadodge, which is the dance that happens when two people attempt to pass each other but end up moving in the same direction," and compiled them in a "Dictionary of Lost Words." Some 150 copies of this alternative dictionary were printed on an old-fashioned letterpress and handed out to writers, journalists and "others who could help get as many of these unique words back into circulation."

If he could put one word back into popular parlance, Ngakane says he'd pick furgle. "It means fumbling in your pocket or bag for keys or a coin that you can't quite get hold of, " he explains. "That's furgling."

Here's the complete collection of non words. Who knows, if you slip them into enough conversations, maybe one day they'll make it into the OED.
