Deus ti salvet, Maria

I came across a religious song in Sardinian that prompted me to write for the first time about this language, not often brought up, otherwise. Material in a minority language such as Sardinian is scarce, unfortunately, so every bit available is always welcome and helpful.

Personally, I haven't delved very much into the minority Romance languages because my goal has always been to be able to master the major Neo-Latin tongues (see here), and I'm able to understand the rest without much trouble. And such is the case with the various "dialects" in Italy. "Dialects" in quotation marks because, even though that's the name given by Italians to these regional idioms, they are not dialects of the standard Italian language, but of Latin itself. Therefore, Sardinian is among many Latin dialects spoken within the boundaries of the Italian nation.
Yes, minority languages is the right term.

With each Romance language, I imagine a Roman speaking a form of Latin. I imagine this Roman in different times and spaces, each influenced by different factors, giving flavor to his own form of Latin — that is precisely the history of the Romance languages, as we know them. Each variety of Romance is a window to the evolution of Latin; and, Sardinian offers quite a unique view.
To understand Sardinian, a knowledge of Italian is almost enough. Knowledge of Italian, plus Spanish and Catalan, and you're able to understand most of it. Add Latin to your language collection, and you reach a high degree of intelligibility.
