Sassarese (Sassaresu or Turritanu) is an Italo-Dalmatian language and transitional variety between Sardinian and Corsican. It is regarded as a Corso–Sardinian language because of Sassari's historic ties with Tuscany and geographical proximity to Corsica. Despite the robust Sardinian influences (in terms of vocabulary and phonology, as well as syntax), it still keeps its Corsican (and therefore Tuscan) roots, which closely relate it to Gallurese; the latter is linguistically considered a Corsican dialect despite its geographical location, although this claim is a matter of controversy. It has several similarities to Italian and in particular the old Italian dialects from Tuscany.
