Coca, spoken near lake Chapala in Mexico, is described as a distinct language in colonial records. Not much but a few morphemes can be ascribed to this language ( Torres Nila, Álvaro J. and Yáñez Rosales, Rosa H. 2018 , Dávila Garibi, J. Ignacio 1942 ) which shows it to be a Southern Uto-Aztecan language ( Torres Nila, Álvaro J. and Yáñez Rosales, Rosa H. 2018: 10-11 , Dávila Garibi, J. Ignacio 1942 ).
