yes! there's old kind of neapolitan and a modern way napolitan! not all of the words we use nowadays are old neapolitan because it became difficult to talk and put also in the modern era of languages etc! due to big grammar rules and lots of old and new neapolitan words neapolitan got confirmed as being an actual language!
