This refers to nations that weren’t settled in our traditional ‘colonial period’, and so constitute old-world languages of Italian, French, Spanish, Romanian, Romansch and Portuguese (the extant ones anyway). Iotl, Romanian is the most isolated of the Romance languages, being on the other side of the continent with Slavs, Germans, Magyars and Albanians in the way. But could an independent Romance language have sustained itself further afield? As far as I know the only truly extinct Romance language is Dalmatian; so I presume this would need an early POD either before or during the Fall of Rome. So how and where could you get this? Egypt? The Ukraine? Uuuuh... Sri Lanka?
