Nundinaenym?

For anyone that asked Jeeves about the word nundinaenym, the reason results were so lackluster is because I just coined it the other day. It describes a word that used to be a trademark and that has now fallen into common use. The suffix -nym means "word", of course. The prefix "nundinae" refers to market day on the Roman weekly calendar prior to around 19 BC. This was the only day of the week that the markets were open and that legal affairs could be conducted.

In my mind, a word that describes active traders and lawyers is perfect for terms like aspirin, kleenex, moxie and now asking jeeves.
