Possibility, Potential

Dean and I went to a gathering at World Cup Esspresso and Wine in Ravenna last night, to celebrate the release of In Posse. It was fun to chat with everybody. And I heard from Tatyana Mishel that "In Posse" (which I thought was some kind of Western cowboy term for gunslingers running around in a group) is actually Medieval Latin "possibility" or "potential." I like that.
