The Jê language family is a group of indigenous languages spoken primarily in Brazil. It includes several languages, such as Kaingang, Xokleng, and Guarani, which are used by various indigenous communities. These languages are part of the larger Macro-Jê linguistic family, which is known for its unique phonetic and grammatical features. Jê languages are characterized by their use of prefixes and suffixes to modify word meanings. They are primarily spoken in the southeastern and southern regions of Brazil, where many indigenous groups maintain their cultural heritage and traditions. Efforts are ongoing to preserve and revitalize these languages in the face of modernization.
