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".
Samaritan Hebrew
The phonology of Samaritan Hebrew is very similar to that of Samaritan Arabic, and is used by the Samaritans in prayer. Today, the spoken vernacular among Samaritans is evenly split between Modern Israeli Hebrew and Palestinian Arabic, depending on whether they reside in Holon (Israel) or in Shechem (i.e. Nablus, in Palestine’s Area A).
