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.
Arab Jews
Jews living in Arab-majority countries speak Arabic, using one of the many Arabic dialects (see also Judeo-Arabic languages) as their primary community language, with Hebrew used for liturgical and cultural purposes (literature, philosophy, poetry, etc.). Many aspects of their culture (music, clothes, food, architecture of synagogues and houses, etc.) have commonality with local Arab population. They usually follow Sephardi Jewish liturgy, making them one of the largest groups among Mizrahi Jews. Most of the population was either forced out, fled or voluntarily left after the founding of Israel in 1948, for the new Jewish state or to Western Europe, and a few went to the United States and Latin America. The term was not commonly used until the modern era.
