Paleo-Sardinian is thought to have left traces in the island's onomastics as well as toponyms, which appear to preserve grammatical suffixes, and a number of words in the modern Sardinian language.
[3] The author in his analysis of the Paleo-Sardinian language finds only a few traces of Indo-European influences (*ōsa, *debel- and perhaps *mara, *pal-, *nava, *sala), which were possibly introduced in the Late Chalcolithic through Liguria.
[5] According to Max Leopold Wagner: So e.g. sakkáyu, -a, sakkáġġu, -a is in Sardinian a lamb or a goat of a year or a year and a half; brings to mind the Aragonese segało, Catalan sagall, Béarnese sigàlo «goat of the same age», which my colleague Rohlfs combined with the Basque segaila «chèvre d'un an» which seems to be derived from the Basque sekail, segail «svelte», sakaildu «décharner, maigrir».
Certain coincidences between Sardinian and Albanian are also notable.Bertoldi and Terracini[citation needed] propose that the common suffix -ara, stressed on the antepenult, was a plural marker, and they indicated a connection to Iberian or to the Paleo-Sicilian languages.
[16] Other Paleo-Sardinian tribes of possible Indo-European stock were the Lucuidonenses from the north of the island, who might have been originally from Provence, where the toponym Lugdunum is attested, and the Siculensi, perhaps related to the Siculi from Sicily, from the Sarrabus region.
