Yao is a Bantu language in Africa with approximately 1 million speakers in Malawi, half a million in Tanzania, and around 450,000 in Mozambique. There are also some speakers in Zambia. In Malawi, the main dialect is Mangoche, mostly spoken around Lake Malawi. In Mozambique, the main dialects are Makale and Massaninga. The language has also gone by several other names in English, including chiYao or ciYao (the prefixed form), Achawa, Adsawa, Adsoa, Ajawa, Ayawa, Ayo, Ayao, Djao, Haiao, Hiao, Hyao, Jao, Veiao, and waJao. In Malawi, most Yao speakers live in the Southern Region near the southeast tip of Lake Malawi and bordering Mozambique to the east. In Mozambique most speakers live in Niassa Province from the eastern shore of Lake Malawi (Lago Niassa) to the Lugenda River up to where it meets the Rovuma River. In Tanzania most speakers live in the south central, Mtwara Region, Masasi district and in the Ruvuma Region, Tunduru district, east of Lake Malawi along the Mozambican border. In common with very many vernacular languages in Africa, it has historically enjoyed little official recognition, and literary work in the region where Yao is spoken has taken place in such languages as Arabic, English, German and Portuguese.
