"Jewish languages" refers to languages specific to Jewish communities, especially those in the diaspora. Foremost among Jewish languages is Hebrew, the original language of the Jewish people prior to the diaspora. Once the language of everyday life, Hebrew was eventually replaced by a dialect of Aramaic after the Babylonian exile. However, Hebrew remained in regular use as the language of prayer. Jewish diaspora languages are generally mixtures of Hebrew, Aramaic, and the languages local to the non-Jewish peoples of geographic regions in which Jews settled during the diaspora. Jewish languages are usually written using the Hebrew alphabet.
