I suppose it keeps the archaisms as SpaNIa instead of Spaña (which came apparently from asturiano-cantabrian double N), or have still archaising graphy for rather next words from OTL spanish (as Regiumo for Reino, the "g" being mute.
Furthermore, it would have more arab influence, critically in vocabulary, but in which parts? Randomly or in particular topics? And what about grammary?
Finally, what would be is objective status? A separate language of Spanish, based on Ibero-Romance, or a constituant dialect of Spanish (as the dialects in occitan are inter-understable, without standard language)?
