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.
Biblical Hebrew
The morphology of Proto-Central-Semitic shows significant changes compared with Proto-Semitic, especially in its verbs, and is much like in Classical Arabic. Nouns in the singular were usually declined in three cases: /-u/ (nominative), /-a/ (accusative) or /-i/ (genitive). In some circumstances (but never in the construct state), nouns also took a final nasal after the case ending: "nunation" (final /-n/) occurred in some languages, "mimation" (final /-m/) in others. The original meaning of this marker is uncertain. In Classical Arabic, final /-n/ on nouns indicates indefiniteness and disappears when the noun is preceded by a definite article or otherwise becomes definite in meaning. In other languages, final /-n/ may be present whenever a noun is not in the construct state. Old Canaanite had mimation, of uncertain meaning, in an occurrence of the word "urušalemim" (Jerusalem) as given in an Egyptian transcription.
