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.
Tunisian Arabic
Tunisian Arabic is one of the Arabic languages within the Semitic branch of the Afroasiatic language family. It is a variety of Maghrebi Arabic like Moroccan and Algerian Arabic, which are mostly unintelligible to Modern Standard or Mashriqi Arabic speakers. It has a considerable number of pre-hilalian dialects but is usually considered in its koiné form to be a mostly Hilalian variety of Maghrebi Arabic because it was affected by the immigration of Banu Hilal in the 11th century, as were the other Maghrebi varieties.
