Apart from Italian and the Friulian dialect, in Sauris they still speak a southern Bavarian dialect which is very similar to the dialects of Carinthia and the Tyrol.

While the language of Sauris (de zahrar sproche) has, over time, felt the influence of contact with neighbouring populations speaking Romance languages, it has retained many of its archaic traits derived from 13th century German (althochdeutsch) when the community was founded.

Linguistic research has identified with some degree of precision where the people of Sauris originally came from and when the first settlers arrived. For centuries the language spoken by the people of Sauris was only oral.

The written tradition, still in use today, accompanied by the production of a considerable amount of poetry, didn't take form until the middle of the 19th century. Over the last ten years or so the language of Sauris has been taught in local infant and primary schools.
