1º_ Common name of several American trees, such as Prosopis pallida . 2º_ Rough person, ordinary, of little education and culture. It is said that the origin of this word is Quechua, and is associated with the tree of the previous meaning, for the rough appearance of its trunk; but in reality it is a derogatory Guarani used by the Creoles to name the indigenous people of present-day Paraguay, who spoke that language and lacked formal education.
