The Jê languages are a group of indigenous languages spoken primarily in Brazil. They belong to the larger Macro-Jê language family and are used by various indigenous tribes, including the Kayapó and Xavante. These languages are characterized by their unique phonetic and grammatical structures, which differ significantly from other language families in the region. There are several distinct languages within the Jê group, such as Tupinambá and Guarani. The Jê languages are vital for preserving the cultural identity and heritage of the indigenous peoples who speak them. Efforts are ongoing to document and revitalize these languages, as many are endangered due to external influences and declining speaker populations.
