Leo Rosten, in 'The Joys of Yiddish' distinguishes between Amerikaner and Europisch Yiddish. I'm sure that zilber is probably Europisch. Also, Fay Kellerman uses a lot of Yiddish and Hebrew in her novels. She lives in south California and North Carolina, I think. Her Yiddish is WAY different from the New Jersey Yiddish I learned. Come to think of it, it's different from San Francisco Yiddish, more central European sounding.

A year ago I found an on-line Yiddish dictionary. I'll look again.
