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.
Phoenician alphabet
The Paleo-Hebrew alphabet, used to write early Hebrew, was a regional offshoot of Phoenician; it is nearly identical to the Phoenician (in many early writings they are impossible to distinguish). The Samaritan alphabet is a direct descendant of the Paleo-Hebrew. The current Hebrew alphabet is a stylized form of the Aramaic alphabet, itself a descendant of the Phoenician script.
