The linguistic and historical demarcations between late Vulgar Latin and early Romance varieties in Italy are imprecise. The earliest surviving texts that can definitely be called vernacular (as distinct from its predecessor Vulgar Latin) are legal formulae known as the Placiti Cassinesi from the province of Benevento that date from 960 to 963, although the Veronese Riddle, probably from the 8th or early 9th century, contains a late form of Vulgar Latin that can be seen as a very early sample of a vernacular dialect of Italy.D'Antoni, Francesca Guerra.

The Commodilla catacomb inscription likewise probably dates to the early 9th century and appears to reflect a language somewhere between late Vulgar Latin and early vernacular.
