Semitic languages
The similarity of the Hebrew, Arabic and Aramaic languages was accepted by Jewish and Islamic scholars since medieval times. The languages were familiar to Western European scholars due to historical contact with neighbouring Near Eastern countries and through Biblical studies, and a comparative analysis of Hebrew, Arabic, and Aramaic was published in Latin in 1538 by Guillaume Postel. Almost two centuries later, Hiob Ludolf described the similarities between these three languages and the Ethiopian Semitic languages. However, neither scholar named this grouping as "Semitic".
Hebrew language
Mizrahi (Oriental) Hebrew is actually a collection of dialects spoken liturgically by Jews in various parts of the Arab and Islamic world. It was possibly influenced by the Aramaic and Arabic languages, and in some cases by Sephardi Hebrew, although some linguists maintain that it is the direct heir of Biblical Hebrew and thus represents the true dialect of Hebrew. The same claim is sometimes made for Yemenite Hebrew or "Temanit", which differs from other Mizrahi dialects by having a radically different vowel system, and distinguishing between different diacritically marked consonants that are pronounced identically in other dialects (for example gimel and "ghimel".)
