Introduction
This introduction provides a concise presentation of Yiddish as the foundational vernacular of Ashkenazi Jews and addresses the challenge of how to present the story of the language by explaining the book’s thematic approach to studying Yiddish through the format of a biographical profile. The introduction notes some key distinguishing characteristics of Yiddish, including its complex and dynamic interrelation with other languages and its symbolic stature within different multilingual configurations. In addition, the introduction provides an overview of the distinctive issues that Yiddish raises for the study of languages generally, including language diaspora, language fusion, multilingualism, language ideologies, and postvernacularity.
