the Digo Language and Literacy Project of Bible Translation and Literacy (East Africa). The project has produced basic literacy materials and published a Digo-English-Swahili Dictionary using the new orthography (Mwalonya et al. 2004) as well as a linguistic description in A Grammar of Digo (Nicolle 2013). The Digo New Testament was finished in 2007. All of these materials are based on the Northern Digo dialect spoken in Kenya. One hundred Digo proverbs have been collected and published by Margaret Wambere Ireri, with translations into Swahili, English, and French. References Hinnebusch, T.J. (1973).
