Jewish Languages in Historical Perspective is devoted to the diverse array of spoken and written language varieties that have been employed by Jews in the Diaspora from antiquity until the twenty-first century. It focuses on the following five key themes: Jewish languages in dialogue with sacred Jewish texts, Jewish languages in contact with the co-territorial non-Jewish languages, Jewish vernacular traditions, the status of Jewish languages in the twenty-first century, and theoretical issues relating to Jewish language research. This volume includes case studies on a wide range of Jewish languages both historical and modern and devotes attention to lesser known varieties such as Jewish Berber, Judeo-Italian, and Karaim in addition to the more familiar Aramaic, Judeo-Arabic, Yiddish, and Ladino. "On top of Brill’s Journal of Jewish Languages and a number of recent publications providing systematic overviews of Jewish languages as well as related theoretical discussions, this volume is a valuable addition to the increasing interest in Jewish languages and linguistics." -Wout van Bekkum, Groningen, Bibliotheca Orientalis LXXVI 3-4 (2019)
