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.
Modern Hebrew
Modern Hebrew is classified as an Afroasiatic language of the Semitic family and the Canaanite branch of the North-West semitic subgroup. While Modern Hebrew is largely based on Mishnaic and Biblical Hebrew as well as Sephardi and Ashkenazi liturgical and literary tradition from the Medieval and Haskalah eras and retains its Semitic character in its morphology and in much of its syntax, the consensus among scholars is that Modern Hebrew represents a fundamentally new linguistic system, not directly continuing any previous linguistic state, being a koiné language based on historical layers of Hebrew, as well as incorporating foreign elements, mainly those introduced during the most critical revival period between 1880 and 1920, as well as new elements created by speakers through natural linguistic evolution. A minority of scholars argue that the revived language had been so influenced by various substrate languages that it is genealogically a hybrid with Indo-European. These theories have not been met with general acceptance, and the consensus among a majority of scholars is that Modern Hebrew, despite non-Semitic influences, can correctly be classified as a Semitic language.
