Unlike other Southwestern tribes, the Zuni language is unrelated to other Native American tongues and considered an âisolate.â It should be noted that the Zuni Indians later adopted words from Hopi and Pima tribes to describe certain religious observances and ceremonies.
Because of the importance of language to culture and spiritual traditions, the Zunis are working to retain and preserve that unique language. Europeans first encountered the Zuni in 1539, when Fray Marcos de Niza led an expedition to their pueblo villages in what is now New Mexico.
