Kwangali, or RuKwangali, is a Bantu language spoken by 85,000 people along the Kavango River in Namibia, where it is a national language, and in Angola. It is one of several Bantu languages of the Kavango which have click consonants; these are the dental clicks c and gc, along with prenasalization and aspiration.
Maho (2009) includes Mbunza as a dialect, but excludes Sambyu, which he includes in Manyo.
