I agree. Cairenes do not usually pronounce the letters "th," "dh," or "v."
The foremost Coptic scholar, Dr. Emil Maher (Father Shenouda), on the website of the Coptic church in Rochester, New York writes that those sounds never existed in Hieroglyphic.
http://stshenouda.rochcopts.org/BohairicPronunciation.phpBut why have 2 letters, v and f that are pronounced like “f”?
Father Dr. Maher does not mention the origin of the pronunciation of p like “b”, t like “d”, or j like “g”. I will not stress the pronunciation of e like “a”, in the recording that I listened to, since in many languages the correct pronunciation of vowels is only in the eyes of the beholder.
I’m quite interested in learning the “old” Bohairic pronunciation. It is the best “guess” arrived at by modern scholarship, even though I’m not absolutely sure of its accuracy. But I’m really ignorant about the matter
. Can you suggest a recording of the Lord’s Prayer in “old” Bohairic?
A friend of mine mentioned that a couple of churches in el Minya hire only pastors and deacons from local families that kept the old Bohairic pronunciation in their tradition. This is what I meant by writing that a certain accent “survived in el Minya.” I would like you to confirm this for me, please. Thank you for all the help.
God bless you,
