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.
Lebanese Arabic
Lebanese Arabic shares many features with other modern varieties of Arabic. Lebanese Arabic, like many other spoken Levantine Arabic varieties, has a syllable structure very different from that of Modern Standard Arabic. While Standard Arabic can have only one consonant at the beginning of a syllable, after which a vowel must follow, Lebanese Arabic commonly has two consonants in the onset.Several commentators, including Nassim Taleb, have claimed that the Lebanese vernacular is not in fact a variety of Arabic at all, but rather a separate Central Semitic language, descended from Aramaic with the many Arabic and Turkish loanwords and use of the Arabic alphabet disguising the language's true nature. Taleb recommended that the language be called Northwestern Levantine or neo-Canaanite. This classification is not widely accepted by linguists.
