Yaaku (also known as Mukogodo, Mogogodo, Mukoquodo, Siegu, Yaakua, Ndorobo) is an endangered Afroasiatic language spoken in Kenya. It is Cushitic, but its position within that family in unclear. Speakers are all older adults.
The Yaaku people are former hunter-gatherers and bee-keepers. They adopted the pastoralist culture of the Maasai in the first half of the twentieth century, although some still keep bees. As a result, the Yaaku almost completely gave up their language for Maasai between 1925 and 1936. The variety of Maasai they speak is called Mukogodo-Maasai. Old Yaaku words are still found in bee-keeping vocabulary, for example:
A language-revival movement has started among the Yaaku in recent years, aiming to strengthen the Yaaku identity. In early 2005, Maarten Mous, Hans Stoks and Matthijs Blonk visited Doldol on the invitation of a special Yaaku committee, to determine whether there is enough knowledge of Yaaku left among the people to revive the language. This visit has shown there are few truly fluent Yaaku speakers left, all very old: two women called Roteti and Yaponay, respectively, and a man called Legunai. The latter two are both of the Teritoage set, which means that they must be around a hundred years old. Knowledge of vocabulary is much wider spread in the community. Full language revival is improbable because of the scarcity of fluent speakers, but one of the possibilities for a partial revival is to use Yaaku vocabulary in the framework of Maasai grammar, a strategy that is analoguous to the making of Mbugu, a mixed language of the Usambara mountains in Tanzania.
