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.
Tihamiyya Arabic
The Tihami Arabic or Tihamiyya dialect has many aspects which differentiate it from all other dialects in the Arab world. Phonologically Tihami is similar to the majority of Yemeni dialects, pronouncing the ' () as and the ' () as a velar plosive (the ' pronunciation is also shared with Egyptian Arabic) unlike San'ani and Hadhrami Arabic which pronounce the ' () as . Grammatically all Tihami dialects also share the unusual feature of replacing the definite article ("al-") with the prefix ("am-"). The future tense, much like the dialects surrounding Sanaa, is indicated with the prefix ("š-"), for all persons, e.g. "ša-būk am-sūq" "I will go to the Souq". Some Tihami dialects, such as that spoken in Al-Hodeida, are otherwise fairly similar to other Yemeni dialects in grammar and syntax, differing mainly in vocabulary, while others can be so far from any other Arabic dialect that they are practically incomprehensible even to other Yemenis.
