Now I want to pick up on that word "archaic". Isn't it tempting to think that the ancients were in some way SMARTER than we? There must be a certain "effiiciency" with a language. (English, as an example of a modern language, may simple be "encrusted" with a vast vocabulary) Is it more "efficient" to use a case instead of a preposition? I suspect so.
Well, don't let me distract you. I have to wonder if there are linguists out there in the world at large who could descend upon us and dazzle us with what they already know. In the meantime, I feel like you two are on a linguistic adventure. Keep it up.
