So the quondam Work Research Foundation, a Canadian Neocalvinist thinktank, has changed their name. Problem is, they have changed it to cardus, which is an odd and rare form of the much more normal cardo, from which we get our term “cardinal directions” — i.e. the four points N, S, E, W. The cardo was the main north-south street in the rectilinear grid of an ancient Roman town, intersecting the decumanus at the groma. It’s this urban meaning that WRF doubtless meant to evoke. The problem is, they didn’t pick the more usual form of the word; they picked the form ending in “-us”, which, while more immediately Latin-looking to the English reader, is a fairly rare word — so rare that it didn’t even make it into Lewis and Short’s Latin lexicon.
So they’re not really wrong, as a matter of lexicography. But the problem is this: there is a common word “cardus, and it doesn’t mean “N-S street.” It means, much more commonly, “a thistle.” Is that a clever Neocalvinist double entendre about creation, fall, and redemption? (Gen. 3:18?)
