Does the tag italian-american-english have a meaning, for this site?
Is there an English dialect that is called Italian American English?
You could probably argue for a dialect of English called "Italian American English", but it would not be English as spoken by native Italian speakers. I would not call the latter a dialect because it is not native English.
The Italian American English dialect could be used to describe the particular dialect used by, e.g., Robert De Niro, Al Pacino, etc.
