The first systematic study on the Sardinian language was written in 1782 by the philologist Matteo Madau, with the title of . The patriotic intention that motivated Madau was to trace the ideal path through which Sardinian could grow to be the island's proper national language; nevertheless, the Savoyard climate of repression on Sardinian culture would induce Matteo Madau to veil its radical proposals with some literary devices, and the author was eventually unable to ever translate them into reality. The first volume of comparative Sardinian dialectology was produced in 1786 by the Catalan Jesuit Andres Febres, known in Italy and Sardinia by the pseudonym of , who returned from Lima where he had first published a book of Mapuche grammar in 1764. After he moved to Cagliari, he became fascinated with the Sardinian language as well and conducted some research on three specific dialects; the aim of his work, entitled , was to «write down the rules of the Sardinian language» and spur the Sardinians to «cherish the language of their Homeland, as well as Italian». The government in Turin, which had been monitoring Febres' activity, decided that his work would not be allowed to be published: Victor Amadeus III had supposedly not appreciated the fact that the book had a bilingual dedication to him in Italian and Sardinian, a mistake that his successors, while still echoing back to a general concept of "Sardinian ancestral homeland", would from then on avoid, and making exclusive use of Italian to produce their works.
