Coptic Letters
There are 32 letters in the Coptic alphabet. The first 25 are derived from the Greek letters that have their origin in the Egyptian Hieroglyphic script, the last 7 letters are directly derived from the Egyptian Demotic Script.
It was the language that our Lord Jesus Christ - as a baby visiting Egypt with St. Mary and St. Joseph - heard and spoke. Remember Egypt was the only country our Lord Jesus Christ visited outside his home country.
