Syrian Jews
The Syrian pronunciation of Hebrew is similar to that of other Mizrahi communities and is influenced both by Sephardi Hebrew and by the Syrian dialect of Levantine Arabic. The Syrian pronunciation of Hebrew is less archaic than the Iraqi Hebrew of Iraqi Jews and closer to standard Sephardic Hebrew. That affects especially the interdentals. Nevertheless, Syrian and Iraqi Hebrew are very closely related because of their location and geographic proximity, as is the case with most eastern Jewish communities in the Arabic world other than Yemenite Jews.

Medieval Hebrew
Medieval Hebrew was a literary and liturgical language that existed between the 4th and 18th century. It was not commonly used as a spoken language, but mainly in written form by rabbis, scholars and poets. Medieval Hebrew had many features that distinguished it from older forms of Hebrew. These affected grammar, syntax, sentence structure, and also included a wide variety of new lexical items, which were either based on older forms or borrowed from other languages, especially Aramaic, Greek and Latin.
In the Golden age of Jewish culture in the Iberian Peninsula, important work was done by grammarians in explaining the grammar and vocabulary of Biblical Hebrew; much of this was based on the work of the grammarians of Classical Arabic. Important Hebrew grammarians were Judah ben David Hayyuj and Jonah ibn Janah. A great deal of poetry was written, by poets such as Dunash ben Labrat, Solomon ibn Gabirol, Judah ha-Levi, David Hakohen and the two Ibn Ezras, in a "purified" Hebrew based on the work of these grammarians, and in Arabic quantitative metres (see piyyut). This literary Hebrew was later used by Italian Jewish poets.
