Casamassimese
Pugliese (Casamassimese)
Jersey City (NJ)Community Profile: While many of the first Italian New Yorkers were speakers of Ligurian, Piedmontese, Lombard, and Tuscan varieties, the overwhelming majority have been southerners who spoke forms of Sicilian, Neapolitan, Calabrese, and Pugliese. Given that less than 10 percent of the population spoke the national language (Italian) at the time of unification in the 19th century, most Italian New Yorkers were speakers of these (often mutually unintelligible) "dialects" who only learned Italian later, if at all.

n 2016, a member of the Cristantiello family contacted the Endangered Language Alliance to report that members of her family spoke a language "frozen in time" from Casamassima near Bari in Puglia. As contact has grown with people in the city of Bari and "Italianization" has increased, Casamassimese has lost much of its distinctness in the village, but the Cristantiellos have preserved and even passed down to their children many features of the old way of speaking in their home in Jersey City.
Note that the language above may be used throughout the New York area — this is just one significant site.
