In the Tupi language of eastern South America, the word Carioca (where today is Rio de Janeiro) means Carijo’s house or district, the suffix oca in Carioca the same as oikos in Greek meaning household, so apparently king Car was the leader of the Carians who sailed across the Atlantic from western Anatolia when the Ice Age ended to where today the Tupi language is spoken, the same family as Carib (named for king Car), and Tapioca or Tupioca apparently Tupi’s household.
