Coptic, a descendent of the Egyptian language of the Pharaohs, is generally thought to have died out as an everyday language in the 17th century. Since then it’s been used only in the religous ceremonies of the Coptic Church in Egypt. However, according to the Daily Star Egypt, there are a couple of families who still speak Coptic as their language of daily conversation.
The Coptic speaker mentioned in the article says that she does not speak Coptic with her children because she felt that Coptic was a worthless language to have her children speak, therefore she did not do so when they were young. So, unless there are any undiscovered Coptic speakers out there, the language probably won’t survive for much longer.
