By the way, I was thinking about Noah's challenge to find another English declined noun that takes the place of an entire phrase, like "modulo." The only one I could come up with was "pace," the ablative of the Latin pax ("peace"), which essentially means "with all due respect to" when one is politely disagreeing with someone. Example: "Pace the New York Review of Books, I think that Susan Sontag is a bore."

One more thing. Anyone who tells you that it's pronounced "PAH-chay" is an ignoramus. Any true Latinist will tell you that "PAH-kay" is the way to go.
