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
Finally, in some Semitic languages like Hebrew, words that include the letter lāmed have Arabic cognates that replace it with a Mīm as opposed to Lām, the equivalent letter. For example, skull in Hebrew is גֻּלְגֹּלֶת (gulgolet). Its Arabic cognate is جمجمة (jumjúmah). This gives plausibility to the case of Banu Hamīr and indicates that lām is frequently equated with Mīm.
