If you have ever wondered how the Ancient Egyptian language sounded, listen to the liturgical hymns of the Coptic Church, the only place it is still widely spoken.
First recorded in 3400 BCE, Egyptian is the earliest known language in history, rivaled only by Sumerian. Like all languages, it evolved over its long lifespan, becoming Demotic by 600 BCE and Coptic by 200 CE. It began to decline thereafter, going extinct by the 17th century and surviving only as a religious language, with very few fluent speakers outside of some clergy (my research suggests that only one family is known to speak it as a first language).
There have been sporadic but unsuccessful efforts to revive Coptic for mainstream use. Below is one of the few videos I have found of Coptic being spoken outside of a liturgical context. Superficially, it sounds a lot like Arabic, which isn’t too surprising since it falls under the same large language family of Afro-Asiatic and evolved during centuries of Arab rule (some things do sound familiar to me, such as the term for “and”).
