Only 7 Kenyan elders from the Yaaku tribe of Kenya’s Rift Valley speak Yakunte, a language that the UN has classified as ‘extinct’. After the Yaaku began assimilating into the stronger and bigger Maasai community, they also adopted Maa language. Currently 4,000 people left Yaaku are considered a sub-clan of the Maasai by the Kenyan government. Unfortunately, there is no help, neither national (Kenya), nor international (UNESCO) to save this language from dying.
