Amongst the pre-Columbian languages that still exist common to places such as Izalco and Cacaopera is Nawat Pipil.
The evidence provided by an analysis of the Misumalpan language family, to which the Mayangna languages belong and which also includes Miskitu and the extinct Matagalpan and Cacaopera tongues once spoken in the Nicaraguan highlands and southern El Salvador, indicates the continuous presence of these groups in the region from around 2000BC.
