Ruund language

Ruund (Ruwund), also known as Northern Lunda or Uruund, is a Bantu language of the Democratic Republic of the Congo and Angola. It is highly unusual among Bantu languages for allowing consonantal codas and for its reduced vowel system, in which short /e/ and /o/ have become [i] and [a] respectively, leaving only 3 short vowels.

Another interesting feature of Ruund is that, as with the related Ciluba language, the tones of Proto-Bantu have reversed, so that High has become Low and vice versa. In this language therefore the accented syllables are Low and the default tone is High.
