Istwa Nou

Omotic languages are spoken today across southern Ethiopia. They were once spoken much further north. The evidence is a set of Omotic loanwords sitting inside the Agaw languages of northern Ethiopia, which can only have entered by contact, and the contact has to predate 2000 BCE. That puts Omotic speakers across a large stretch of the Ethiopian Highlands four thousand years ago, well beyond the territory their descendants hold. What moved them was the expansion of Cushitic speaking peoples, which pushed the Omotic communities southward over the following millennia until the map came to look as it does now. The words stayed behind. Borrowed vocabulary is durable in a way that settlements are not, and a handful of Omotic terms embedded in Agaw speech is the surviving trace of a linguistic geography that has otherwise been erased. Ehret works this way throughout, on the principle that languages remember migrations which left nothing at all in the ground.
