Toso also researched the phenomenon of language contact, with special attention to language islands in the Mediterranean basin, from the colonial Ligurian dialect [it] to Tabarchino.[3] In addition, he conducted etymological research on linguistic minorities in Italy and Europe. Thanks to his research on Tabarchino, he was awarded honorary citizenship of Calasetta[4] and Carloforte.[5]
