Dad was from New Bedford. I’m still smiling imagining his Boston’ese :-))
NewBeffud isn’t Bostonese. (I lived nearby in RudEylan for a few years in the late ‘80s.) It’s a distinct accent unto itself.
Boston had several distinct accents when I lived there, from Beacon Hill to Southie to Bay Village to Revere. Leaving aside the melanistic ‘hoods in Roxbury and Dorchester. Forty years on, it probably has a few more.
The lead character in the movie “Good Will Hunting” absolutely nailed the old working-class WASP accent. As distinct from the lower-class Irish accent, which is what the Kennedys spoke. Italians in the North End could be told from those in Revere.
(Doing all the various Boston accents used to be my party trick, but after 40 years in the Midwest I’ve pretty much lost them all.)
“Wicked” is a Maineism, not used in Boston in my experience.
