Guttural R
Many Jewish immigrants to Israel spoke a variety of Arabic in their countries of origin and pronounced the Hebrew rhotic as an alveolar tap , similar to Arabic '. Gradually, many of them began pronouncing their Hebrew rhotic as a voiced uvular fricative , a sound similar or (depending on the Arabic dialect) identical to Arabic '. However, in modern Sephardic and Mizrahi poetry and folk music an alveolar rhotic continues to be used.
Ghil'ad Zuckermann
Zuckermann argues that Israeli Hebrew, which he calls "Israeli", is a hybrid language that is genetically both Indo-European (Germanic, Slavic and Romance) and Afro-Asiatic (Semitic). He suggests that "Israeli" is the continuation not only of literary Hebrew(s) but also of Yiddish, as well as Polish, Russian, German, English, Ladino, Arabic and other languages spoken by Hebrew revivalists.
