コプト語
In defense of the text's authenticity, Ariel Shisha-Halevy, Professor of Linguistics at the Hebrew University of Jerusalem and a leading expert on the Coptic language, concluded that the language itself offered no evidence of forgery. King also found examples from a new discovery in Egypt that has the same kind of grammar, showing that at least one unusual case is not unique. While some experts continue to disagree about the other case, King notes that newly discovered texts often feature grammatical or spelling oddities which expand our understanding of the Coptic language.
