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.
Judeo-Tripolitanian Arabic
Judeo-Tripolitanian Arabic (also known as Tripolitanian Judeo-Arabic, Jewish Tripolitanian-Libyan Arabic, Tripolita'it, Yudi) is a variety of Arabic spoken by Jews formerly living in Libya. Judeo-Tripolitanian Arabic differs from standard Libyan Arabic in that it closely resembles the original dialect of the sedentary population, whereas much of Libya's population now speaks Bedouin-influenced varieties of Arabic. A reference grammar is available.
