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 definite article
Weingreen also states that the original form of the Hebrew "ha-" was in fact "hal". Hebrew, then, dropped the final "l" to achieve "ha"- while Arabic softened the "h"- to a hamza, resulting in "al"-. However, there is no evidence supporting the existence of "hal" from ancient Hebrew texts. In fact, as early as the 6th century BC both "han" (a probable predecessor of the Hebrew "ha") and "al" were being used simultaneously in different Arabic dialects, namely Northern and Central.
