Jeffrey Shandler tells the multifaceted history of Yiddish in the form of a biographical profile, revealing surprising insights through a series of thematic chapters. He addresses key aspects of Yiddish as the language of a diasporic population, whose speakers have always used more than one language. As the vernacular of a marginalized minority, Yiddish has often been held in low regard compared to other languages, and its legitimacy as a language has been questioned. But some devoted Yiddish speakers have championed the language as embodying the essence of Jewish culture and a defining feature of a Jewish national identity. Despite predictions of the demise of Yiddish-dating back well before half of its speakers were murdered during the Holocaust-the language leads a vibrant, evolving life to this day.
