السومو

Sumo (Mayangna) is one of the two surviving Misumalpan languages, sister to Miskito (msu/miq). The Misumalpan family is a small isolated language family of Central America (Nicaragua, Honduras), comprising only Sumo and Miskito as living languages plus several extinct varieties. The Sumo (or Mayangna, the autonym) people are concentrated in the Bonanza-Rosita-Siuna mining triangle of the Caribbean Coast Autonomous Region of Nicaragua, with smaller populations in Honduras's Mosquitia. Linguistically, Sumo shares Misumalpan features with Miskito: SOV constituent order, postpositions, complex polypersonal verb morphology, and a tonal system. The Mayangna identity has been the focus of community-led revitalization since the 1990s, with the Mayangna Yamni Indigenous Federation supporting language preservation.
