Sephardi Jews whose members have formally reverted to Judaism, leading to the emergence of Neo-Western Sephardim (see group below). The Jewish Agency for Israel estimates the Sephardic Bnei Anusim population to number in the millions. Their population size is several times larger than the three Jewish-integrated Sephardi descendant sub-groups combined, consisting of Eastern Sephardim, North African Sephardim, and the ex-converso Western Sephardim (both New World and Old World branches). Although numerically superior, Sephardic Bnei Anusim are, however, the least prominent or known sub-group of Sephardi descendants. Sephardic Bnei Anusim are also more than twice the size of the total world Jewish population
Sephardi Hebrew the Ashkenazi pronunciation was derived from that of Palestine in Geonic times (7th-11th centuries) and that the Sephardi pronunciation was derived from that of Babylonia. The theory was supported by the fact that in some respects, Ashkenazi Hebrew resembles the western dialect of Syriac, and Sephardi Hebrew resembles the eastern dialect: Eastern Syriac "Peshitta" as against Western Syriac "Peshito". Ashkenazi Hebrew, in its written form, also resembles Palestinian Hebrew in its tendency to "malē" spellings (see Mater lectionis). Others, including Abraham Zevi Idelsohn, believed that the distinction is more ancient and represents the distinction between the Judaean and Galilean dialects
