While it's true that both terms ("parable" and "parabola") in their various
different meanings or contexts do derive from the same Greek word (parabole)
they are not the same words at all (it's like saying "pasta" and "paste" are
the same words -- beware the vermicelli at that dinner table!) And, of
course, a rainbow is neither a parable nor a parabola.
