Arthur Jeffery (1893-1959), an Anglo-Saxon orientalist, was trained as a Methodist priest and worked for Christian mission all his life. The Foreign Vocabulary of The Qur’an, was his PhD thesis submitted to the University of Edinburgh (1929) and later published in 1938 (Baroda). In his book, Jeffery listed 325 words of the Qur’an as foreign. The most influential foreign language on the Qur’anic vocabulary, for him , was Aramaic-Syriac, the language of Christian religious literature at the time of the Prophet and, he claims, of the Jews of Madina. He seemed to have approached the issue with some religious and linguistic presuppositions.
