Inamis
Inamis (Enimas), South American aborigines, a branch of the Guaycuras, whose territory lies between the Paraguay and the Pilcomayo rivers east and west. They are the Lingoas of the Portuguese, and the Lenguas of the Spaniards, these words meaning "tongue," in reference to the tongue-shaped wooden ornament which they attach to the under lip. The Inamis had formerly the reputation of being the most warlike and predatory of all the Gran Chaco Indians; but in recent times they have entered into friendly relations with the Brazilians, to whom they supply horses in exchange for cattle.
