He learned this in his Christian college.
This is shocking in light of the fact that the yod is used as a letter in all ancient languages in which it is seen, and it is pronounced.
The yod is used in the name of the Jewish and Christian God, YHWH, [יחוח]
The Hebrews and Phoenicians used the same letter [Yōd] in the same way, and it is the Yōd that gave rise to the Greek letter Iota [ι].
Jesus spoke of the Yōd when he said not one iota [yod, the smallest letter of the alephbet] ... of the Law would pass from the Law until all be fulfilled.
Yodh (also spelled yud, yod, jod, or jodh) is the tenth letter of the Semitic abjads, including Phoenician Yōd 
, Hebrew Yōd י, Aramaic Yodh 
, Syriac Yōḏ ܝ, Persian Ye ی, and Arabic Yāʾ ي.
The Yōd is not a fake letter.
