Illui (Hebrew: עילוי or עלוי also ilui; pronounced [ʔiˈluj] plural: illuim) is a young Torah and Talmudic prodigy or genius. The Hebrew term and title is applied to exceptional Talmudic scholars among Orthodox Jews. It is used among English speaking and Yiddish speaking Orthodox Jews to identify, as a type of mark of honor, those who have been blessed with greater mental and intellectual capabilities than the average intelligent Torah scholar.
