Jew . . . ?
Sorry to counter here, ER, but Jew isn’t exactly a place...
My Jewish mother-in-law is from Brooklyn, and it's quite easy to spot it.
My Jewish wife was born and raised in sunny Panama, but I detected no accent from her at all. Many American colloquialisms seemed to go right over her head, which I took to be a kind of listrening accent, one that managed to make her all the cuter. Some Jews in her congregation here in Ohio said she spoke Yiddish with an odd accent, though.
I suspect you likely meant the stereotypical TV-Jew from the Olde Country, one who speaks with that Olde Country flavor,. or possibly a first generation American, still under the influence of his community?
