Is the " Abruzzese " dialect differs from Italian language ?
Might want to check on users from Italy like @Hampsicora or @Berny Devlin for a stronger opinion on the matter. From what I understood of Wikipedia, Abruzzese is a dialect/variation of another dialect, Neapolitan. But it's, obviously, better to ask for a native to give an opinion.
It can be stated that every town in Italy has its own dialect. They can be bundled up according to the province or region i.e. as "Neapolitan" or "Campano" but there are still variations present.
The answer to the original question is yes there are differences. To get an idea, compare songs in a dialect against their Italian translation, like this: https://lyricstranslate.com/en/i-te-vurria-vasá-io-vorrei-baciarti.html-0
The Abruzzese is a language related to the Neapolitan group (middle southern) but has several differences from the Neapolitan in the strict sense.
I can understand Neapolitan fairly well (I also made a few translation from Neapolitan) but unfortunately I can hardly understand the Abruzzese, it’s one of the most difficult Italian dialects for me.
