Yiddish language

Yiddish is a West-Germanic language commonly spoken by people of Jewish heritage. Though usually written in the Hebrew alphabet, from a language typological standpoint it is a dialect of German, with lexical admixtures from Hebrew language and, at least in some dialects, phonological innovations adopted from Slavic, esp. Polish. The name "Jiddish" derives from the southwestern German dialectal pronunciation of Standard German Jüdisch, meaning "Jewish."
