Influence on other languages

In addition to Modern Hebrew and New York English, especially as spoken by yeshivah students (sometimes known as Yeshivish), Yiddish has influenced Cockney in England and to some degree the city dialects of Vienna and Berlin. French argot has some words coming from Yiddish.

Paul Wexler proposed that Esperanto was not an arbitrary pastiche of major European languages but a Latinate relexification of Yiddish, a native language of its founder. This model is generally unsupported by mainstream linguists.

Yiddish had an influence on Jewish Swedish a dialect of Swedish used by Jews with loanwords from Hebrew and Yiddish. And Yiddish had an influence on Hungarian with extra influence on Jewish Hungarian, a dialect of Hungarian spoken by Hungarian Jews. Yiddish had influence on other European Jewish ethnolects like Jewish Russian and Jewish French. These ethnolects are shown in various pieces of media across various mediums both digital and physical.
