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.
Phoenicianism
The Arabic language is considered to exist in multiple forms: formal Arabic, commonly known as Modern Standard Arabic (a modern incarnation of Koranic or Classical Arabic), which is used in written documents and formal contexts; and dialectal variants, numbering some thirty vernacular speech forms, used in day-to-day contexts, and varying widely from country to country. The one spoken in Lebanon is called "Lebanese Arabic" or simply "Lebanese", and it is a type of Levantine Arabic, which, together with Mesopotamian Arabic, is classed by matter of convenience as a type of Northern Arabic. The point of controversy between Phoenicianists and their opponents lies in whether the differences between the Arabic varieties are sufficient to consider them separate languages. The former cite Prof. Wheeler Thackston of Harvard: "the languages the 'Arabs' grow up speaking at home, are as different from each other and from Arabic itself, as Latin is different from English."
