Other comments: Ópata is an extinct language spoken by the Opata people of northern central Sonora in Mexico and Southeast of Arizona in the United States. It was believed to be dead already in 1930, and Carl Sofus Lumholtz reported the Opata to have become "Mexicanized" and lost their language and customs already when traveling through Sonora in the 1890s.

Eudeva and Ópata two closely related Uto-Aztecan languages. Although the Opata Nation, an unrecognized tribe, considers the language inactive, they are in the process of its language revitalization. The Fundación OPATA-TEGUIMA launched the first-ever Opata Living Dictionary in 2021 in collaboration with Living Tongues Institute for Endangered Languages.

Ópata has only recorded traditional numerals from 1 to 10 many years ago, not sure if they were used a traditional decimal or vigesimal system before, New data for numbers after ten is required.
