Searching for the family of Fr Pigol Bassili eg Nofer Bassili, Vert Bassili, Rano Bassili or the family of Maurice AbdelMessih, or Ounas Gerges. The thing is that all these family started talking Coptic in the early 20th century, as a reconstructed form of the language. There are many neologisms, and it sounds like a pidgin form of the language, as compared to Coptic text written in manuscripts. There is also a lot less Greek vocabulary in particular in favour of other words, this has not been observed in Coptic words of Arabic, Hebrew, Syriac, Latin, Akkadian or Persian etymology.
