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".
Judeo-Arabic languages
Like other Jewish languages and dialects, Judeo-Arabic languages contain borrowings from Hebrew and Aramaic. This feature is less marked in translations of the Bible, as the authors clearly took the view that the business of a translator is to translate.Jews in Arabic, Muslim majority countries wrote—sometimes in their dialects, sometimes in a more classical style—in a mildly adapted Hebrew alphabet rather than using the Arabic script, often including consonant dots from the Arabic alphabet to accommodate phonemes that did not exist in the Hebrew alphabet.
