The Goa'uld language is spoken by the Goa'uld and Jaffa. The Goa'uld language started out as the Unas Language, but it was limited by the vocal abilities of the Unas. As the Goa'uld started to take more human hosts, their language developed and became a primary influence for Ancient Egyptian. It is now the lingua franca of the Milky Way galaxy and has retained that status in spite of the fall of the System Lords.
