From the original description of this kind of object, I get the image of
two networks (the two categories) which have only one vertex in common. Or
to get more physical about it - which is a good way to generate mental
images of real-world analogues whose names we can steal - two fishing nets
or string bags tied together at a single knot. So what's a good name for
that knot? A "junction"? A "contingence"? A "taction"? It's where two
worlds touch, like a weak spot in the space-time continuum where the
threads have worn away, or the Wood Between the Worlds in the Narnia
novels. How about "crossover object"?
