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.
Arabic language in Israel
Modern Standard Arabic (also known as Standard Arabic or Literary Arabic), is currently an auxiliary language in Israel and its use on government documents is mandated by law. Spoken Arabic dialects are spoken primarily by Arab citizens of Israel and Israeli Druze, as well as by some Mizrahi Jews, particularly those of the older generation who immigrated from Arabic-speaking countries. In 1949, 156,000 Palestinian Arabs were left inside Israel's armistice line, most of whom did not speak Hebrew. Today the majority of Arab Israelis, who constitute over a fifth of the Israeli population, speak Hebrew fluently, as a second language.
