“Why do most people pronounce the first two words of the Kaddish as יִתְגַּדַּל וְיִתְקַדַּשׁ when the גר”א demonstrated that those two specific words are not Judeo-Aramaic but לשון הקדש and should thus be pronounced יִתְגַּדֵּל וְיִתְקַדֵּשׁ? (See ס’ מעשה רב.)”
I’ve wondered about this since I heard it in a yeshivish Shul thanks for clarifying.
