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".
Palestinian Arabic
Palestinian Arabic is a Southern Levantine Arabic dialect, spoken by most Palestinians in Palestine and israel and in the Palestinian diaspora populations. Together with Jordanian Arabic, it has the ISO 639-3 language code "ajp", known as South Levantine Arabic. Further dialects can be distinguished within Palestine, such as spoken in the northern West Bank, that spoken by Palestinians in the Hebron area, which is similar to Jordan and south-western Syria.
