Other comments: Duwet or Guwet has a counting system combines a counting system based on two with tallying on hands and feet. However, SIL linguists Sep and Ruth Gisileng (September 6, 2011) reported that they did asked the people in the village and the old people have died and the young people are using English counting system and they said their counting system is fading. They only count to twenty by counting their fingers and toes and that’s it. Nobody really knows how to count from twenty upwards.
