Other comments: Guajajára or Zeʼegete, Guazazzara, Tenetehára is spoken by about 14,000 speakers out of  28,900 ethnic population in Maranhão state: Pindaré, Grajaú, Mearim, and Zutiua rivers. Quite similar to the other Tupi languages, Guajajára has a very simple counting system only have ''1, 2, 3, 4 and many'' . In recent years they have adapted the number system of Brazilian Portuguese speakers around them. In the 70s I heard of an attempt to use fingers, hands, etc., but only one mane ever tried it and could never decide whether 20 was four hands or two hands and two feet.
