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.
Moab
Most of our knowledge about Moabite comes from the Mesha Stele, which is the only known extensive text in this language. In addition there are the three line El-Kerak Inscription and a few seals. The main features distinguishing Moabite from fellow Canaanite languages such as Hebrew are: a plural in "-în" rather than "-îm" (e.g. "mlkn" "kings" for Biblical Hebrew "məlākîm"), like Aramaic and Arabic; retention of the feminine ending "-at" or "-ah" which Biblical Hebrew reduces to "-āh" only (e.g. "qiryat" or "qiryah" "town", Biblical Hebrew "qiryāh") but retains in the construct state nominal form (e.g."qiryát yisrael" "town of Israel"); and retention of a verb form with infixed "-t-", also found in Arabic and Akkadian ("w-’ltḥm" "I began to fight", from the root "lḥm".)
