The views of these theological scholars however are contradicted by the studies of Hebrew and Aramaic philologist E. Y. Kutscher, Professor of Hebrew Philology at the Hebrew University of Jerusalem, and member of the Hebrew Language Academy, who noted that the although the "ayin" became a silent letter it is never dropped from written forms nor is its effect on the preceding vowel lost (the change of the "u" to the diphthong "ua") as would have had to occur if "Yeshu" were derived from "Yeshua" in such a manner.
